Frequently Asked Questions
Can I reuse the same signature on future documents?
Each session lets you draw or upload a signature fresh, so you have full control over exactly what's placed on each document.
Is my file uploaded to a server?
No. This tool runs entirely in your browser — your file is never uploaded anywhere, so nothing ever leaves your device.
