Key Features
🔒 Your Files Never Leave Your Device
Unlike tools that upload your PDFs to remote servers, our tool processes everything locally in your browser using WebAssembly. No server ever sees your documents — not even us. This makes it one of the most private PDF tools available, completely free.
Frequently Asked Questions
Is this tool safe for attorney-client privileged documents?
Yes — all processing happens entirely in your browser using WebAssembly. Your PDFs are never uploaded to any server, making this appropriate for confidential legal documents.
Does this create true redactions or just visual overlays?
True permanent redactions. Our tool uses MuPDF to delete the underlying text and image data from the PDF file structure — the content is removed, not just hidden with a black box.
Can I redact scanned PDFs or image-based documents?
Yes. For scanned PDFs (image-only), use the draw redaction box feature to visually cover content. For text-layer PDFs, use Search & Redact for pattern-based removal across all pages.
Is this PDF redactor completely free?
Yes, 100% free. No account needed, no watermarks, no file size limits. All processing happens in your browser.
Are my files safe and private?
Absolutely. Your PDFs never leave your device. All redaction happens locally in your browser using WebAssembly — we never see your files.
What is the difference between redaction and drawing a black box?
True redaction permanently removes the underlying text data from the PDF file. Our tool uses MuPDF to ensure sensitive content is deleted from the file structure, not just hidden visually.
