Redact PDF · Private

For sensitive resumes and contracts, Redact PDF runs 100% locally — no upload, data cleared when you close the tab.

How to Use

  1. Upload — Click or drag PDF/images to the dashed zone. Multi-file and large files (<100MB per batch recommended) are read locally only.
  2. Configure & process — Set pages, angle, password or quality, then hit “Calculate / Process”. Redact PDF runs via WebAssembly and pdf-lib in your browser — no server queue.
  3. Preview & download — Check pages, size and thumbnails on the right, then download. Batch jobs download one by one; tweak and re-run if needed.

Tips & Notes

  • Page syntax: Use 1,3,5-7 or 1-10,15; empty means all. Out-of-range pages are ignored.
  • Privacy & size: Everything runs locally — no server upload. For large files, process in batches of 50–100 pages.
  • Fidelity: Fonts and vectors are preserved where possible. For scanned PDFs, run OCR/searchable PDF first, then convert.

अक्सर पूछे जाने वाले प्रश्न

Will files be uploaded? Is Redact PDF safe?

No. Redact PDF runs 100% in your browser via File API; no network upload, memory cleared when you close the tab.

Processing failed or download blocked?

Check page ranges, passwords and file integrity. If the browser blocks multiple downloads, allow “automatic downloads” or click links one by one.

How to chain with other security tools?

Combine workflows: organize pages first, then compress/convert for submission, then protect/sign for delivery.
