Redact a contract without uploading it.
Sharing a signed contract as a template, an exhibit, or a reference means handing over names, pricing, and terms you may not want a third party to see. KeptPDF removes what you choose 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 price is not the same as removing it.
Most redaction is a colored overlay. The party names, the pricing schedule, and the signatures all stay in the file underneath, and a different viewer or a copy-paste brings them back.
Real redaction destroys the text in the contract, so a covered name or price cannot be recovered.
KeptPDF flattens each redacted page so nothing survives under the box, and it works in your browser, so the original contract 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.
What to strip before a contract leaves your hands
Auto-detect surfaces the names and identifiers. The commercial terms only you can judge are one click from permanent removal.
Party names and signatures
The named parties, signatories, and contact details are flagged so you can share the structure without naming who signed it.
Pricing and terms you choose
Fees, rates, and negotiated terms are a judgment call, not automatic PII. Box any clause or figure you want gone and it is permanently removed.
Account and reference numbers
Tax IDs, account numbers, and reference codes embedded in the agreement are surfaced for your review.
Scanned or signed copies
If the executed copy is a scan, KeptPDF OCRs the pages first so it can find and remove text inside the image.
How to redact a contract
Three steps, entirely on your device. Permanent, verifiable, no upload.
Open your contract
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 contract, so you are not hunting for each one by hand.
Never uploaded
There is no upload step. The contract 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.
