KeptPDF

什么是 KeptPDF？

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.
