Bulk PDF Redaction (No Upload)
Process multiple PDFs privately: load a batch, auto-mask sensitive data with regex presets (emails, phones, IDs, IPs, IBANs, tokens), and save redacted copies - everything stays in your browser.

Tip: add up to 10 PDFs per batch. Larger batches may slow down browser memory.

Custom terms:
Pages with a match are rebuilt as pictures with the matches painted over, so the matched text is removed from the file (those pages lose their text layer). Text that is part of an image, or on pages without a text layer, is not detected: use Redact PDF to mark such areas by hand.

How it works
- Add PDFs and choose regex presets (emails, phones, IDs, IBAN, IPs, tokens, custom terms).
- Pick a mode: Local (client-side, max 10 files) or Server (PHP/GS, max 100 files / 1 GB).
- Local: redacts in your browser and downloads a ZIP containing only the redacted files; the originals are never added to it. (The Server option currently uses the same in-browser processing.)
- Every page with a match is re-rendered as an image (about 200 dpi) with boxes burned over the matches; its original text, vector content and annotations are not in the output. Each result is a new document without the original's metadata, bookmarks, attachments or form data, and the tool re-opens each result and checks it before the ZIP is created.
Processing details, limits, and tips
- Local: best for small/medium files; capped at 10 to avoid browser memory issues.
- Server: up to 100 files or 1 GB total; uploads one-by-one with per-file progress and individual downloads.
- Patterns covered: emails, phone numbers, SSN-like IDs, IP addresses, IBAN, long IDs (MRN-style), tokens/keys, plus custom terms you add.
- Outputs append "_redacted" to filenames; final ZIP bundles all processed files.
Security and privacy
All processing is local - files never leave your browser. Close the page to clear any in-memory data.
