KeptPDF
Redact for real. Do everything. Upload nothing.
KeptPDF is a full PDF suite that runs entirely in your browser: redact, sign, OCR, compare, Bates, fill, extract tables, and more. Your file is never uploaded, because there's no server to upload it to. The flagship is redaction that actually works: auto-detect SSNs, names, DOBs and account numbers, then destroy the text underneath, no black box to copy-paste around, plus a SHA-256 certificate. The new Privacy X-ray finds live text hiding under failed redactions. Verify it in Airplane Mode.
Hi Product Hunt, I'm John, the founder of KeptPDF.
KeptPDF started in a hospital room. A family member was in the ICU, and I was trying to understand it from my phone at the bedside, surrounded by medications and doctors' notes I couldn't make sense of. I wanted to ask an AI for help, but it was full of private medical details I didn't want to hand to anyone. Most tools that could have helped wanted me to upload the file to their server first. From a hospital room, on a phone, I wasn't willing to do that.
So I built what I needed. A full PDF suite that runs entirely in your browser, on any device. Your file is never uploaded, because there's no server to send it to.
The redaction does more than auto-detect. It walks you through each uncertain match so you can approve or skip it in a tap. Anything you want to add, you just tap a word to redact it or drag across a line, no drawing boxes by hand (unless you want to). It's fast even on a phone. Nothing is removed until you say so, and what does go is deleted from the text underneath, not just covered, with a SHA-256 certificate of exactly what came out.
A few other things it does:
An X-ray tool that finds text still hiding under black boxes someone else left behind, even one that a tool you trust produced. A software update can quietly lift a redaction that was done right, so check the file you're about to send, not just the app you made it in.
Anonymize a file before you paste it into ChatGPT, Claude, or Grok: it swaps the real names for placeholders the AI still understands, so it gets the full picture without seeing who it's about.
Plus 24 more tools (sign, OCR, compare, Bates, fill, extract tables). No install, no account.
You don't have to trust me on the privacy. Load it, turn on Airplane Mode, and it still works, because your file never leaves your device.
It's free to use, no account. Pro is $29/mo (the first 100 founding members lock it at $19/mo for life), and Practice is $99/seat for teams. 30-day money-back guarantee.
I'd love your feedback, especially on the redaction. Roast it, break it, tell me what's missing. Ask me anything.
