FAQ
Is the stamp legally binding?
The stamp is just an image, not a legal digital signature or certificate. Use an e-contract service for important agreements.
Can I use my own seal image?
Yes. Load a scanned seal image (transparent PNG recommended) and place it.
Can I change position and size?
Click or drag on the preview to position it; set the size in mm.
Are my files uploaded to a server?
No. All processing happens inside your browser on your device; files are never sent anywhere. After the page loads it even works offline.
Is it free? Do I need an account?
It is free, with no sign-up, login or usage limit.
