PDF Redactor & Sanitizer
Upload a PDF, review detection candidates, burn in irreversible masks, optionally strip metadata, verify the output, and export a count-only audit report—all on your device.
- Pattern detection with regional profiles
- Manual rectangle redaction on page preview
- Raster burn-in for irreversible masking
- Optional metadata sanitization & verification
Your PDF never leaves this device. Detection matches and file bytes stay in memory only and are not sent to analytics or servers.
- Automatic detection lists candidate matches only. You must review every highlight before redacting.
- Detection cannot guarantee finding every secret, hidden layer, or embedded object in a PDF.
- If nothing is detected, that does not mean the document is safe to share without manual review.
- Verification checks structural signals after processing; passing verification is not a guarantee of absolute safety.
- Redacted pages are rasterized, which removes selectable/searchable text on those pages.

About PDF Redactor & Sanitizer
This Solasu tool supports an eight-step workflow—Inspect, Detect, Review, Redact, Sanitize, Verify, Report, and Download—for PDFs that must be shared with reduced sensitive content.
Redaction uses raster burn-in so masked text cannot be recovered from the text layer on affected pages. Optional sanitization reuses the same metadata removal approach as our PDF Metadata tool. Scanned pages can use local OCR (Document OCR engine) before detection.
Detection is candidate-only
Regional profiles match emails, phones, URLs, card-like numbers, and more from extractable text. Zero matches does not mean the file is safe—manual review and rectangles are essential.
Auto highlights (amber) and manual regions (blue) are visually distinct; use category toggles and undo/redo before applying redaction.
Irreversible masking and sanitize modes
Selected areas are rasterized with black, white, or custom fill. Searchable text is lost on those pages by design.
Choose redaction-only, redaction plus metadata cleanup, or full sanitize (metadata, annotations, links where supported).
Privacy-first, local processing
PDF bytes and matched strings never leave your browser. Analytics events exclude filenames and content.
Export JSON, CSV, or PDF audit reports with counts and verification status for internal records.
FAQ
Does auto-detection remove all personal data?
No. It surfaces candidates only. You must review highlights and add manual regions where needed.
Does verification passed mean the file is 100% safe?
No. Verification reports structural checks after processing; it is not a legal or absolute anonymity guarantee.
Can I redact scanned PDFs?
Run OCR on scanned pages to estimate word boxes locally, then detect and redact like text PDFs.
Are files uploaded to a server?
No. Everything runs client-side in your browser.
Is the original PDF modified?
No. A new redacted PDF is generated for download; the source file stays unchanged in memory.
