About PDF Editor

Last updated: 2026-09-29

PDF Editor is a free web app for editing PDF files. It runs in your browser, with nothing to install and no sign-up required for files on your computer. Pages are rendered by pdf.js, the open source PDF engine behind Firefox, and edits are written by pdf-lib; both run inside your browser.

Your PDF is processed in the browser instead of being uploaded to a PDF Editor server. Google sign-in is requested only when you choose a Google Drive action, and the limited drive.file permission lets the app work with files you select or create - not everything in your Drive.

What you can do

  • Open PDF files from your computer or Google Drive, including password-protected ones, and start a new blank PDF or one made from JPEG and PNG pictures.
  • Rotate, delete, reorder, duplicate, and insert pages, merge in pages from another PDF, and extract a page range.
  • Fill forms, add text, drawings, highlights, pictures, stamps, and a signature, and white out an area.
  • Add a watermark, page numbers, or a header and footer, and view, edit, or strip the document properties.
  • Protect a PDF with an open password and permissions, or remove a password you know.
  • Update the file on your computer or in Google Drive, download a separate copy, export pages as images, or extract the text and pictures.
  • Recover unsaved edits after an interruption when browser storage is available.

How PDF Editor works

Opening, rendering, editing, and writing happen on your device in the browser. A Google Drive PDF you can edit autosaves as you work; a PDF from your computer is written only after your first manual save, and it autosaves from then on. A recovery draft may also update in local browser storage, but a draft never overwrites the image on your computer or in Drive.

When you use Google Drive, the PDF travels directly between your browser and Google through Google's APIs.
