Stamp and signature cleaning history

This page contains all SigCleaner results for your account. Every time you upload a scan and remove the background from a stamp or clean a signature, the final PNG file with a transparent background is automatically saved to your history. This is convenient: you don't need to process the same stamp twice.

Files with removed stamp backgrounds are stored for 1 year for guests and indefinitely for registered users. You can download the extracted signature from a photo in PNG format at any time — ready to insert into Word, PDF, a contract, or an electronic document management system.

If you want to automatically save and retrieve stamp cleaning results programmatically, use REST API.

Need to remove the background from a new stamp or signature? Go to главную страницу, upload a photo or scan, and SigCleaner will remove the background in seconds. No software installation required.
