Remove a phone number from a PDF without uploading it.
A phone number is a direct line to a person, which is exactly why you do not want it on every copy you send. KeptPDF finds the numbers and permanently destroys the text, all in your browser. The original never leaves your device. Review the result before you share it.
A box over a phone number still leaves it in the file.
Most PDF tools redact by drawing a rectangle on top. The number stays in the file underneath, recoverable by moving the box or copying the page text. A covered phone number that comes back is the contact you were trying not to share.
Real redaction destroys the digits in the PDF, so a covered phone number cannot be uncovered.
KeptPDF flattens each redacted page so nothing survives under the box, and it all happens in your browser, so the file with the number intact is never uploaded to a server. You can verify it yourself in the network tab.
A filled rectangle just sits on top of the text. Move it, switch viewers, or copy the page, and the hidden content is back.
The page is flattened to an image, so the text underneath is destroyed. There is nothing left to uncover.
Phone numbers in every format
Numbers are written a dozen ways, so auto-detect looks for all of them, plus the name and contact details that travel with them.
Every common number format
(555) 123-4567, 555-123-4567, 555.123.4567, +1 555 123 4567, and numbers tagged with a label. Auto-detect flags each for your review.
The name and email with it
A phone number is part of a contact block. The name and email next to it are surfaced too, so you can remove the whole set.
Numbers buried in the body
Auto-detect scans the whole document, so a number in a paragraph or a signature line is flagged the same as one in a header.
Numbers inside a scan
If your PDF is a scan or a photo, KeptPDF runs OCR first, so it can find and remove a phone number printed inside an image.
How to redact a phone number
Three steps, entirely on your device. Permanent, verifiable, no upload.
Open your PDF
Drop your file onto the page or pick it from your device. It loads into your browser, and nothing is sent anywhere.
Mark what to redact
Auto-detect finds names, dates, Social Security numbers, account numbers, and more. Draw boxes over anything else you want gone.
Download the clean copy
Save it. The marked content is permanently gone: the page is flattened to an image, not hidden behind a box. Give the result a quick review before you share it.
Permanent removal, nothing uploaded.
True text destruction
Each redacted page is flattened to an image, so the text layer is gone, not just covered with a shape. Content under a redaction box cannot be copied, selected, or recovered. Review the result before you share it.
Auto-detect the obvious stuff
One pass finds names, dates, phone numbers, Social Security numbers, addresses, and emails across the whole PDF, so you are not hunting for each one by hand.
Never uploaded
There is no upload step. The PDF is processed entirely in your browser, so the original is never part of a network request and never sits on anyone else's server.
Redaction certificate (Pro)
Pro adds a signed PDF and JSON audit record listing every redacted span, category, and page, which is handy for productions and compliance files. Anyone you send it to can re-check the fingerprint in their own browser, with nothing uploaded.
When the document goes out but the number should not
Resumes and applications posted publicly, screenshots shared online, contact sheets, and any record you forward to someone you do not fully know.
