Manually mark and permanently burn out signatures or handwriting from documents. Pixel-level redaction.
Free is enough for most one-off jobs. Pro raises the file and batch caps; Pro + Media unlocks GB-scale streaming and unlimited duration.
Larger files supported on Developer (5 GB CSV) and Enterprise (unlimited). All processing happens in your browser — files never reach a server.
Open a PDF page or image with the signature visible.
Drag a rectangle over the signature; the region is rasterized and overwritten.
Download the redacted file with the signature burned out at pixel level.
0 bytes uploaded. Signature Burner runs entirely in your browser. Files, passwords, and PGP private keys never leave your device. No analytics fire during processing — only after you opt-in to dashboard audit logging.
No. Pixels under the rectangle are overwritten — there's no underlying layer to restore.
Yes. Only the rectangle region is replaced; everything else is lossless.
