Automatic cleanup
Empty space is trimmed away, so the image drops into a document without extra cropping.
Stays on your device
Your signature is processed in this app and never uploaded. It is gone when you close it.
Free, with no strings
No account and no watermark. Ads pay for SignClean, and you never watch one to export.
