Drop a PDF, then draw boxes over what must go.
Redact PDF
Draw boxes on page previews. Every page with a box becomes an image with the box burned in, so nothing remains beneath it. The output is re-opened and checked before you can download it. Redacted pages lose searchable text.
Good to know
- The download is blocked unless the check passes: redacted pages must hold no text, metadata must be clean, and sampled text from those pages must be gone.
- Pages with a box become images and lose searchable text. Other pages keep their text, but lose links, comments and form fields, because those can reach redacted content.
- Document metadata, outlines, attachments and form data are dropped from the output. You still choose what to box, so review every page.
Your files stay on your machine
This tool runs entirely inside your browser tab. Nothing is uploaded, stored, or sent to a server — close the tab and every trace is gone.
These are the free ones — see the full suiteHow big a file can it take?
There is no upload, so there is no upload limit — but the work happens in this tab, which means your browser’s memory is the budget. Nothing here will refuse a file for being large; a big enough one simply gets slow and, eventually, reloads the tab. The figures below are rules of thumb on a desktop browser, not enforced caps. On a phone or tablet, expect a good deal less.
- Previews are drawn for every page, so page count binds: comfortable to about 500 pages.
- Each redacted page is held as a large image, so hundreds of redacted pages make a large output file.
Password-protected PDFs are declined whatever their size — unlock the file first. If a run does die on a long document, splitting it into volumes and working through them one at a time is the reliable way round it.
