Redact PDF in your browser
Need to hide Social Security numbers, account details, medical information, or names before sharing a PDF? A black box in a normal editor still leaves the text underneath, ready to be copied. Redact PDF burns the black boxes into the page and rebuilds every page as an image, so the text is truly gone.
- Real redaction. Hidden text, fonts, and layers are removed, not just covered.
- Draw as many boxes as you need across up to 20 pages, then check every page.
- You confirm before anything is exported.
- The unredacted file never leaves your device.
How to use Redact PDF
- Choose a PDF (up to 20 pages) and drag boxes over everything sensitive.
- Check the preview of every page to make sure nothing is peeking out.
- Confirm, then click Apply redactions to download the cleaned PDF.
Technical notes & limits
- Up to 20 pages per PDF. Every page becomes an image, so selectable text, links, and bookmarks are removed.
- It won’t find sensitive information for you. You need to mark and check every area yourself.
Why real redaction rebuilds the page
Plenty of embarrassing leaks happened because someone drew a black box in a PDF editor and the text underneath was still there to copy and paste. To make sure nothing survives, InBrowserPDF turns each page into an image, paints solid black over the areas you marked, and builds a completely new PDF from those images.
Check every page before you share
Because each page becomes an image, you lose searchable text, links, bookmarks, and form fields. Look through every page of the result. If you also want to clear hidden document details like the author name, run Remove PDF Metadata afterward.
Frequently asked questions
Can someone copy or uncover the text behind a redaction box?
No. The page is turned into an image with the marked areas painted black, so there’s no text left underneath to copy.
Will the rest of my PDF still have selectable text after redaction?
No. To be safe, every page is rebuilt as an image so no hidden text or fragments slip through.
Why is Redact PDF limited to 20 pages?
Rebuilding pages in high resolution takes a lot of browser memory, and good redaction needs careful page-by-page checking anyway.
