Frequently asked questions
Is my file uploaded anywhere?
No — this tool runs entirely in your browser using JavaScript/WebAssembly. Your file is never sent to a server.
Is there a file size limit?
Free accounts can process files up to the limit shown on this page; signing up for Pro raises that limit substantially.
Is this a legally binding e-signature?
No. This draws an image of your signature onto the page — it's a visual mark, not a certificate-based digital signature, and it doesn't verify identity or create the kind of audit trail a legally binding e-signature service provides.
