Bank statements, payslips, visa letters, tenancy agreements and NHS correspondence all carry more personal data than the recipient actually needs. DocClean detects and redacts that data — and converts or compresses the result — entirely inside your browser. Your document is never uploaded to a server.
Automatically detect names, National Insurance numbers, emails, phone numbers, postcodes, bank details and more using OCR, then draw manual blocks over anything the detector misses. Choose a compliance profile (Maximum Privacy, CCPA/CPRA-lite, Social sharing, or a fully custom rule set) and export a version that has the sensitive content permanently removed rather than merely hidden.
OpenTurn a redacted or original PDF into other formats you can actually use — page images, a Word-compatible document, or a bundled archive — without the file ever leaving your device.
OpenBundle multiple files into a single ZIP archive to make them easier to email or upload as one attachment. ZIP compression is lossless and works best on text-heavy files — already-compressed formats like most PDFs, JPEGs and videos may shrink little or not at all. Best run after redaction, on the final safe version of a document.
OpenDrag one in or choose a file. It's read directly in your browser's memory.
OCR flags likely personal data; add manual blocks for anything specific to your document.
Download the redacted file, then search and copy/paste-test it before you send it on.
Most online PDF tools work by uploading your file to a remote server, processing it there, and sending back a result. That means trusting a third party with whatever is inside the document — often exactly the kind of sensitive material you're trying to redact in the first place. DocClean runs PDF rendering, OCR and redaction locally, in your browser's memory, so the document itself never has to leave your computer to be processed.
That said, no tool replaces your own judgement. After exporting, always search the result for names, postcodes or reference numbers and try copy/pasting text from the redacted areas — the difference between real redaction and simple masking is exactly whether that test passes.
Different documents carry different risks. These guides cover what to redact — and what to leave in — for common UK document types.
A practical, one-page checklist to run through before sharing any sensitive document — whether or not you use DocClean to prepare it.
Optical character recognition is what lets a redaction tool find text in a scanned document. Here's how it works and what its limits are.
