One drag, then use it forever

Edit any PDF you find, in one click

Drag the button below to your bookmarks bar once. After that, whenever you land on a PDF anywhere — an email attachment, a government form, a client’s file — click it to open that exact PDF straight into the editor.

Short answer

Drag "Edit in Ofcpdf" to your bookmarks bar. Next time you are looking at a PDF in your browser, click it — the file opens directly in the editor in a new tab. The PDF's bytes travel from that tab to this one, browser to browser, and are never sent to any server, including ours.

Drag — do not click. Clicking it here, on this page, does nothing useful; it only works once it is a real bookmark and you use it on an actual PDF.

How to add it

  • Bookmarks bar showing? If not, show it first — Ctrl/Cmd + Shift + B in Chrome, Firefox, and Edge.
  • Drag the button above straight onto that bar. It will show up as a small bookmark labelled "Edit in Ofcpdf".
  • On mobile, most browsers let you add a bookmark and edit its URL afterward — add any bookmark, then edit it and paste the link location from this page in its place.

What actually happens when you click it

The bookmark only does anything on a page your browser is already treating as a PDF — a direct PDF link, or an attachment opened in its own tab. Click it there, and it: reads that exact file from the tab you are already on (never a new request to anywhere else), opens Ofcpdf in a new tab, and hands the file over directly between those two tabs. Nothing is uploaded at any point — the same promise every other tool on this site keeps, extended to a file that started on someone else's page entirely.

Why it only works on a PDF you are already viewing

A bookmarklet runs with the permissions of the page it is clicked on. Fetching a PDF from a different website than the one currently open is exactly the kind of cross-origin request browsers correctly block by default — and a version of this that routed around that by sending the file through a server somewhere would quietly break the one promise that matters most here. What is left is the honest version: it works on the file you can already see, using only the access you already have to it, moved directly from your browser to your browser.
