Frequently Asked Questions
- Is redaction permanent?
- Yes. The tool burns black filled rectangles into the PDF page content using pdf-lib. The underlying text is not recoverable from the output file.
- Is my PDF uploaded to a server?
- No. All processing happens entirely in your browser using PDF.js and pdf-lib. Your file is never sent anywhere.
- Can I undo a redaction?
- Yes — before applying. You can delete individual redaction boxes from the sidebar. Once you click Apply & Download, redactions are permanent in the downloaded file.
- Does it work on scanned PDFs?
- Yes. Since redactions are drawn visually over the rendered page, they work on scanned/image PDFs just as well as text PDFs.
- What file size can I redact?
- Large files may take longer to process since everything runs in your browser. Most PDFs up to 50MB work fine.
