Questions
Frequently asked
No. SnapTools applies permanent redactions to the PDF file itself. Once you download, the redacted areas are baked into the document and cannot be reversed. Always verify before saving your final version.
Runs in your browser. Files are never uploaded.
Browser-based processing handles most standard documents without issues. Very large files (100+ MB) may experience slower performance depending on your device's RAM, but there's no hard upload limit since files stay local.
SnapTools includes a layer inspection feature that shows you exactly what's hidden versus visible. Check the redacted areas in the preview before downloading to confirm no sensitive content bleeds through.
Completely. Your file never leaves your browser or device. We don't upload, store, or access your documents—you maintain full privacy and control from start to finish.
