Is this a legally binding electronic signature?

This is a visual signature — the image of a signature drawn, typed, or uploaded. Like hand-signing a printed page, it is accepted for most everyday uses. For legal processes that require a cryptographic digital signature (eIDAS, DocuSign, Adobe Sign), use a dedicated service — this tool does not produce a cryptographic signature inside the PDF structure.

Where are my signatures stored?

In your browser's localStorage, not on any server. Up to 3 recent signatures are kept so you can reuse one quickly. Deleting a signature from the list removes it from localStorage immediately.

Does the output lock down the signature?

Yes. After you click Apply, the signature is flattened into the PDF — baked into the page image. It can't be dragged, removed, or replaced in the output file without editing the PDF in another tool.

Is my PDF uploaded anywhere?

No. The entire signing flow — load, placement, flatten, download — happens in your browser via pdfjs-dist and pdf-lib.
