Why there's no upload step
Signing a document shouldn't require uploading it to a stranger's server. This tool lets you draw a signature and stamps it directly onto the page you choose using pdf-lib, entirely in your browser.
Is my PDF uploaded anywhere?+
No. Signing happens entirely in your browser.
Is this a legally binding e-signature?+
This adds a visual signature image to the page. It doesn't provide cryptographic signing, audit trails, or identity verification the way dedicated e-signature services do.
Can I sign multiple pages?+
Currently one page at a time — run the tool again on the result to add another signature elsewhere.
