Learn how to open, edit, and save PDFs, and fix common problems.

Open a PDF from your computerTop

PDFs from your computer are read directly in the browser. They aren't uploaded to a PDF Editor server, and you don't need to sign in.

How to open a PDF

  • Use the start page. Select Open PDF From Computer and pick a file.
  • Use the File menu. Choose File > Open > Open from computer..., or press Ctrl/Cmd + O.
  • Drag and drop. Drag a PDF from your desktop or a folder window onto PDF Editor.
  • Paste a PDF. Copy a PDF file in another app, return to PDF Editor, and paste it.
  • Open a recent PDF. Recent files are listed on the start page and at the bottom of the File > Open submenu; select one to reopen it.

What you can open

PDF Editor opens PDFs up to 100 MB, including scans, forms, and password-protected files. It saves your work as a PDF.

Open a PDF from Google DriveTop

Select Open From Google Drive on the start page, or choose File > Open > Open from Google Drive... in the menu bar. Sign in with the account that can access the PDF, then choose it in the Google file picker.

Good to know

  • Access is limited. PDF Editor can work with files you select or create with the app, not everything in your Drive.
  • Shared files are supported. You can open a PDF from a shared drive or a file shared with your account. If you only have view access, use File > Make a copy to continue in a copy of your own in My Drive, which opens in a new tab.
  • Use the same Google account. If the picker shows the wrong files, close it and make sure you're signed in with the account that has access.

Create a new PDFTop

Select Create New PDF, choose File > New PDF, or visit pdfeditor.co/new. A blank Letter page opens as untitled.pdf. The file is created when you save.

From pictures

Choose File > New PDF from images... and select JPEG or PNG files. Each image becomes a page, using its own size or a Letter or A4 sheet. The PDF takes its name from the first image.

More pages

  • Insert > Blank page... in the Page actions menu adds a page after the current one, in Letter, A4, or the current page's size, portrait or landscape.
  • Insert > Image as page... adds one page per picked JPEG or PNG.
  • Insert > From PDF... adds another PDF's pages after the current page.

Work with pagesTop

Open Pages and select a thumbnail. Hold Shift or Ctrl/Cmd to select several. Page actions appears beside the Rotate buttons. Drag thumbnails to reorder pages, or use Alt + Up/Down. With no selection, Rotate applies to the current page.

The Page actions menu

Select thumbnails and open Page actions, or right-click a thumbnail. Right-click below the thumbnails to insert at the end or find whole-document commands. Edit also includes Rotate, Delete page, and Duplicate page for the current page.

  • Duplicate, Move up, Move down; Insert and Whole document submenus. Copy or rearrange the selected pages; insert after them; reverse, fold or flatten the whole document.
  • Insert: Blank page..., Image as page..., From PDF... Add pages after the selected ones, as described under Create a new PDF. From PDF... is how you combine PDFs.
  • Crop page... Drag a rectangle over the page to keep just that part. The rest of the page is hidden, not deleted, and Undo brings it back.
  • Resize pages... fits and centers pages on Letter or A4 sheets. Flatten form fields and remove annotations you added first. Pages with existing links or annotations cannot be resized. Use Undo to restore the original pages.
  • Remove other pages... keeps a page range, such as 1-3, 7, and removes the rest. Use Undo to restore them. Autosave writes this change to your file, so make a copy first if you want to keep the original.
  • Whole document includes Reverse page order, Two pages per sheet, and Flatten form fields. Two pages per sheet combines page pairs on landscape sheets, with the same limits as Resize pages. Flatten form fields makes field values part of the page so they can no longer be filled in.
  • Tools > Whiteout area... covers an area with white. It is not redaction: the covered text remains in the PDF and can still be searched or exported. Do not use whiteout to hide confidential information.

Undo, redo, and revert

Use Undo and Redo to step through page changes and annotations. Edit > Revert all changes returns to the PDF you opened. You can undo a revert, but cleared form values cannot be restored.

Zoom, find, full screen, and themes

Use the toolbar to zoom, jump to a page, or Find text. The View menu includes fit options, Two-page view, and controls to show or hide the sidebar, menus, and toolbar. Full screen hides the menus and toolbar; press Esc to return. The header theme button switches between System, Light, and Dark. PDF pages keep their original colors.

Fill forms, annotate, and signTop

Fill in text fields, checkboxes, and other form controls directly on the page. Your entries are saved in the PDF. XFA forms are read-only, and PDF scripts do not run.

Annotation tools

  • Draw. Draw freehand with the pen.
  • Add text. Click a page to place a text note. Text notes use Latin characters; other characters are dropped with a notice.
  • Highlight. Select text on a page to highlight it.
  • Image. Place a JPEG or PNG on the current page; drag its corners to resize it.
  • Color, text size, and thickness settings appear in the panel for the active tool or the selected note.
  • Sign, beside Annotate, lets you draw, type, or upload a signature. Move or resize it on the page. You can save it in this browser for next time. Signatures are drawings, not digital certificates.
  • Stamp in the Annotate panel, or Add stamp... under Annotate in the Tools menu, places an APPROVED, DRAFT, or CONFIDENTIAL stamp, a check mark, or an X on the page.
  • Tools includes Add watermark, Add page numbers, Add Bates numbers, and Add header and footer. Each opens the same dialog with the matching option selected.

Press the active Draw, Add text, or Highlight tool again, or press Esc, to stop using it. Added text, drawings, images, and signatures are saved as PDF annotations that other readers can move or delete. Existing annotations can be viewed but not edited here. Comments and replies are not supported.

Passwords and permissionsTop

Enter the password when you open a protected PDF. It stays in memory for this session only. Restoring a recovery draft requires the password again. Saving keeps the same password and permissions unless you change them.

Add or change protection

Choose Tools > Protect with password.... Set an open password, a permissions password, or both, then choose the allowed actions. Protection applies when you save, using AES-256 encryption. The permissions password grants full access. Lost passwords cannot be recovered.

Remove protection

Choose Tools > Remove password, then save to remove protection. This also cancels protection you added but haven't saved yet.

Document properties

File > Properties... shows file details. Tools > Edit metadata... changes the title, author, subject, and keywords, or removes all properties. Editing properties also removes XMP metadata, an extra copy of metadata some apps store in the PDF. Use Undo to restore the previous properties.

PrintTop

Choose Print... in the File menu or press Ctrl/Cmd + P. Pick all pages, the current page, or a page range such as 2-5, 8, then press Print to open the browser's print dialog. Pages print as they appear in the editor, including rotations, filled form fields, and annotations, as 150 dpi images.

To download page images instead, see Images, exports, and large files.

Images, exports, and large filesTop

Download pages or embedded images

File > Export > Pages as images... downloads one PNG or JPEG per page at the resolution you choose. Allow multiple downloads if your browser asks. If only one file downloads, check the browser's download permission for pdfeditor.co before trying again.

File > Export > Embedded JPEG images downloads only JPEG pictures stored in the PDF. It does not turn each page into an image. Use Pages as images... for scans or pictures that this command cannot extract.

File > Export > Text as .txt downloads the page text. A scanned page may contain only an image, with no text to export.

Add images to a PDF

Choose JPEG or PNG images up to 25 MiB each. The PDF and its added files must fit within a 200 MiB session limit. Convert other image formats in another app first. If an image cannot be added, try a smaller copy.

File size and memory limits

PDF Editor opens PDFs up to 100 MB. Scanned pages, high-resolution images, and saving can use much more memory than the file size. A smaller file can still exceed your browser or device memory. Added images have separate format and size limits.

Save your work before reloading or closing tabs. For image exports, try fewer pages or a lower resolution. To edit fewer pages, make a copy first, then use Page actions > Remove other pages....

Save and exportTop

Drive PDFs autosave when you have edit access. Local PDFs autosave after your first save grants access or chooses a destination. Check the status beside the filename to see whether your changes are saved.

Save to the current file

  • A local PDF. Press the Save button or Ctrl/Cmd + S. In Chrome, Edge, Opera, and other supported Chromium browsers, approve the write-permission prompt the first time it appears.
  • A Google Drive PDF. Save writes back to that Drive file when you have edit access.
  • A protected PDF. Save keeps the password and permissions the file was opened with.

Choose a different destination

  • Save as..., in the File menu, creates a new local file and sends future saves to it.
  • Edit in Drive, on the app bar and as Edit in Google Drive in the File menu, creates a Drive file and sends future saves to it.
  • Update in Drive appears when another app sends a PDF that came from Drive. Sign in to the account that owns the file, then select the original when Google asks for access. Future saves go to that file. If it is unavailable, save a new Drive file instead.
  • File > Make a copy saves your edits beside the original in Drive and opens the copy in a new tab. If that folder is unavailable, the copy goes to My Drive. It is named "Copy of" followed by the original name. Your current tab and Undo history stay unchanged.
  • Download, on the app bar (also Download a copy in the File menu), downloads the current PDF while keeping you in the file you were already editing.

Attachments

Attachments... in the Tools menu lists the files embedded in the PDF. Download one, remove one, or add files of your own; the changes are written when you save.

If a local save or download fails

Check that the device has free space, approve any browser permission prompt, and confirm that downloads are allowed for pdfeditor.co. If saving the current file keeps failing, use Save as... in the File menu or Download on the app bar to create a separate file.

Save back to ZIP ExtractorTop

When you open a PDF from ZIP Extractor, Save sends your edits back to its open tab. Keep both tabs open until PDF Editor confirms the save.

If the save is not confirmed, switch to the ZIP Extractor tab, then try Save again in PDF Editor. If the tab was closed or the connection cannot be restored, choose Download a copy to keep your edits.

A message saying a copy was downloaded means you have a local file; it does not confirm a save to ZIP Extractor. Check your browser's downloads before closing the editor.

Share, move, and find a Drive PDFTop

These commands are available for PDFs in Google Drive. Use Edit in Drive to save a local PDF there first.

  • Share. Choose Share or File > Share... to open Google's sharing dialog. Your available options depend on your access. If it can't open, choose Open in Drive to share there.
  • Move. Choose File > Google Drive > Move... and pick a folder. You can also click the save status and choose Choose folder.... Edit access is required.
  • Open. File > Google Drive > Open opens the file's Drive page in a new tab.
  • Locate. File > Google Drive > Locate opens the file's folder in Drive in a new tab, with the file selected.
  • Make a copy. Choose File > Make a copy to save your edits to a new Drive file. It opens in a new tab. If your browser blocks the tab, choose Open copy in the message.

If the original changed somewhere elseTop

If another person or app changes an open file, PDF Editor pauses saving to avoid overwriting their changes.

Your choices

  • Keep your version. Confirm that you want your edited PDF to replace the other version.
  • Use the newer version. Load the file that changed elsewhere instead of overwriting it.
  • Keep both. Use Save as..., Make a copy, or Download before deciding.
  • Decide later. Dismiss the warning and keep editing. Autosave stays paused for that file, and nothing is overwritten until you decide.

Autosave and recovery draftsTop

Autosave updates your PDF file. Recovery drafts keep a separate backup in this browser on this device.

When the file autosaves

  • A Google Drive PDF you can edit autosaves as you work; no first manual save is needed.
  • A PDF from your computer autosaves after your first manual save, which grants file access or picks the destination.
  • Autosave pauses if the file changed somewhere else. The status beside the filename shows what has been saved.

How recovery drafts work

  • A separate backup. After a short pause, PDF Editor stores your PDF and edits in this browser, if storage is available. Drafts never overwrite your saved file.
  • Recovery after an interruption. After a reload, crash, or closed tab, PDF Editor can restore the latest unsaved draft. You must reenter the password for a protected PDF; passwords are never stored.
  • A fresh Undo history. Recovery restores your PDF and edits, but not the steps to undo them.
  • Turn drafts off. Uncheck File > Save recovery drafts to stop saving new drafts on this device. Existing drafts can still restore.

Important

Draft saved means the browser backup is current. Your PDF file may still need saving. If storage is blocked or full, keep the tab open and save your PDF before leaving.

Keyboard shortcutsTop

On a Mac, use Cmd where this list shows Ctrl. For the full list, open Help > Keyboard shortcuts in the app, or press Ctrl + /.

  • Open from your computer: Ctrl + O
  • Open from Google Drive: Ctrl + Shift + O
  • Save: Ctrl + S
  • Save as: Ctrl + Shift + S
  • Print: Ctrl + P
  • Find: Ctrl + F
  • Undo: Ctrl + Z
  • Redo: Ctrl + Shift + Z (on Windows and Linux, Ctrl + Y also works)
  • Rename: F2
  • Full screen: Ctrl + Shift + F
  • Close a menu, a dialog, a tool, or an untouched new PDF: Esc

With the page area or toolbar focused (click a page first), single keys work too:

  • Zoom in / out: + / -
  • Fit to page: 0; Actual size: 1
  • Rotate right / left: R / Shift + R
  • Delete the selected pages: Delete

In the Pages sidebar, the arrow keys move between pages, Shift extends the selection, Space toggles a page, Enter shows it, and Alt + Up / Down moves the selected pages.

Privacy and your filesTop

Opening, rendering, editing, and writing the saved PDF happen in your browser.

When data leaves your device

  • Google Drive. A Drive file travels directly between your browser and Google when you choose a Drive action.
  • Recovery drafts and saved signatures. Both stay in this browser on this device.

See the Privacy Policy for complete details.

TroubleshootingTop

The editor does not load

Reload the page. If the editor still won't load, try a private window to check whether an extension is blocking pdfeditor.co. Then update your browser or try another current browser.

The PDF does not open

Check that the file is a PDF under 100 MB. Damaged PDFs may not open or may have missing pages. If a password prompt keeps returning, check the password for this file. When contacting Support, include the error message, file size, and page count.

Text shows as boxes or is missing

Some PDFs refer to fonts they don't contain. PDF Editor substitutes a standard font where it can; the saved file is unchanged by this, and it will look as before in a reader that has the font.

The editor is slow or runs out of memory

Save your work, close other tabs and apps, then try again. See file size and memory limits for ways to reduce memory use.

If a Google Drive request failsTop

Check your connection, Google account, file access, and Drive storage. A request may also fail if your sign-in expired or Google has a temporary problem.

What you can do

  • Check your connection and try the action again.
  • Make sure PDF Editor is using the Google account that has access to the file.
  • Save a local copy before reloading, then sign in again.
  • If Drive saving is unavailable, use Download to keep a local copy.

Google Drive download quota exceededTop

Google temporarily limits downloads when a file has been downloaded too many times in a short period. PDF Editor can't override that limit.

What you can do

Wait and try again later, ask the owner to make another copy, or open a different copy of the PDF if one is available. The limit belongs to the Drive file, so changing browsers usually won't help.

Download disabled by the file ownerTop

The owner of a shared Drive file can prevent viewers and commenters from downloading or copying it. PDF Editor respects that setting.

What you can do

Ask the owner for edit access, a downloadable copy, or permission to download. Signing in with another account helps only if that account already has the required access.

File flagged by Google DriveTop

Google may block a PDF it has flagged as malware, spam, or abusive content. PDF Editor doesn't bypass Google's warning or download policy.

What you can do

Open Google Drive directly and review Google's message. If you own the file and believe the flag is wrong, follow Google's available review or download steps. Don't open a file you don't trust.

Local file changed, moved, or became unavailableTop

A recent file may be unavailable if it was moved, renamed, deleted, or changed by another app, or if the browser lost access.

What you can do

  • Select Open PDF From Computer and choose the file again.
  • Approve the browser's permission prompt if one appears.
  • If another app changed the file, reopen it to load the latest version or save your current edit under a new name first.
  • Remove a broken recent entry; this doesn't delete the file itself.

View-only PDFsTop

With view-only access, you can edit the PDF here but cannot save over the shared Drive file. Save a copy to keep your changes.

Keep your own version

Use Make a copy in the File menu to continue in a copy of your own in My Drive, which opens in a new tab, or Save as... in the File menu or Download on the app bar. If the owner disabled downloads and copies, ask them for permission.
