How to redact a PDF online for free
Drawing a black box over text in a PDF editor often leaves the words underneath. Redactify finds the private details and replaces the actual text.
- 01
Open text redaction
Go to the Text page and choose Upload Files.
- 02
Add the PDF
Redactify reads the text and finds emails, phone numbers, card numbers, IBANs, VAT and ID numbers, passwords and API keys.
- 03
Check the results
Every item found is listed. Click one to leave it visible if you need it.
- 04
Pick a style
Use standard placeholders, partial masking (j***@***.com), realistic fake data, or consistent tokens.
- 05
Remove hidden data too
Open the Documents page to remove the author name, comments and other hidden details from the original PDF.
Questions
- Is my PDF uploaded?
- No. Everything runs in your browser and the file never leaves your device.
- Does it work on scanned PDFs?
- Only PDFs with real text. Scanned pages are pictures and need text recognition first.
