Remove a date of birth from a PDF without uploading it.
A date of birth is half of what someone needs to open an account in your name, and it sits on forms, records, and applications you share all the time. KeptPDF blacks it out 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 birth date still leaves it in the file.
Most PDF tools redact by drawing a rectangle on top. The date stays in the file underneath, recoverable by moving the box or copying the page text. For something as reusable as a birth date, that is exactly the leak you were trying to close.
Real redaction destroys the date in the PDF, so a covered birth date cannot be brought back.
KeptPDF flattens each redacted page so nothing survives under the box, and it all happens in your browser, so the file with the date 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.
The birth date, and what sits next to it
A date is only sensitive in context, so KeptPDF surfaces the dates tied to a person along with the details that pair with them to identify you.
Dates that look tied to a person
Auto-detect flags dates next to a name or a label like "DOB" or "Date of Birth" for your review. A standalone date you can box by hand in one click.
The name it belongs to
A birth date plus a full name is most of an identity. Names are surfaced too, so you can remove the pair, not just the number.
SSNs and ID numbers nearby
The same form usually carries a Social Security or account number. Auto-detect catches those so you can take them out in the same pass.
Dates printed in a scan
If your PDF is a scan or a photo, KeptPDF runs OCR first, so it can find and remove a birth date that exists only inside an image.
How to redact a date of birth
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.
Anywhere a form asks for more than it needs
Job and rental applications, medical and school forms, and any record you forward where the birth date is not the point.
