Questions
Is this a legally valid signature?
It adds an image of your handwritten signature, like signing a printed page and scanning it. That is accepted for many everyday forms, but some contracts require a certified digital signature — check with whoever asked you to sign.
Is my signature saved?
No. It exists only in this browser tab and is gone when you close the page.
Are my files uploaded anywhere?
No. The tool runs entirely in your browser, so your files never leave your device and nothing is kept after you close the page. You can check it yourself: once the page has loaded, turn on airplane mode — the tool keeps working.
Is it free? Is there a file limit?
Yes, it is free, with no sign-up and no watermark. There is no upload limit because nothing is uploaded; very large files are limited only by your device’s memory.
