RedactSnap vs PDF24
A PDF24 redaction alternative with automatic detection
PDF24 is free, needs no account and flattens redacted pages, which makes it a solid choice. Its online tools process files on PDF24's servers in Germany, though, and redaction is manual. RedactSnap redacts in your browser on any operating system and finds common personal information for you.

When PDF24 is the better choice
If you are on Windows, redact by hand and want unlimited free use, PDF24 Creator runs offline on your PC and is hard to beat on price. Its online tools also cover far more than redaction.
When RedactSnap is the better choice
On a Mac, a Chromebook or a locked-down work machine where you can't install software, RedactSnap gives you local processing in a browser tab. Smart Scan flags names, contact details and ID numbers, which saves time on long documents.
Frequently asked questions
Is PDF24 redaction permanent?
PDF24 says redacted pages are converted to raster images when you save, so the redaction can't be undone. RedactSnap works the same way, flattening every page on export.
Is my file uploaded anywhere?
No. RedactSnap reads the PDF with your browser's File API and processes it in memory on your device. There is no upload endpoint and no server-side copy of your document. You can confirm this by opening your browser's network tab while you redact.
