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 appropriate for sensitive medical documents?
Yes — your PDFs are processed entirely within your browser and never uploaded to any server. Your patients' information stays on your device at all times.
Can I redact specific fields like dates of birth or patient IDs?
Yes — use the Search & Redact feature to find and remove specific text patterns across all pages instantly, or draw manual redaction boxes over any area.
Does it work with scanned patient records?
Yes. For scanned documents, use the draw redaction box tool to cover sensitive areas visually. The redacted output permanently removes those areas from the file.
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.
