Server-local true PDF redaction with PyMuPDF
Redact PDF
Apply real PDF redactions to matching text terms.
Know what happens before you upload.
A temporary per-request workspace is cleaned when processing ends.
Search relies on extractable text; words inside images or scans are not found without OCR. Matching depends on the PDF text layer, so the result must always be reviewed manually.
After redaction, search the result for every sensitive term and try copying text from each redacted area. For highly sensitive documents, review every page manually.
Upload your file to start
A copilot that understands this tool.
Ask what a setting means, whether this is the right tool, how to recover from an error, or what to do with the result next. Infinity receives safe context from this page — not the file contents automatically.
What this tool is good at — and where to be careful.
When this tool makes sense
Removing repeated sensitive words or numbers from a text-based PDF before sharing a sanitized copy.
What the engine actually does
The tool searches for the terms you provide, adds redaction annotations at the matched locations, applies the redactions, and writes a new PDF. This is different from merely drawing a black rectangle over hidden text.
What it does not promise
Search relies on extractable text; words inside images or scans are not found without OCR. Matching depends on the PDF text layer, so the result must always be reviewed manually.
A 20-second quality check
After redaction, search the result for every sensitive term and try copying text from each redacted area. For highly sensitive documents, review every page manually.
Frequently asked questions
Is this just a black box overlay?
No. The engine applies PDF redactions to matched text before saving the new copy.
Does it redact text inside images?
Not automatically. Image content requires OCR or another workflow before text matching.
