Sign PDF
betaDraw, type or upload your signature and place it on the page — kept in your browser, never uploaded
How it works
Open the PDF, press Sign and draw your signature (pressure is honoured on a pen), type your name in one of four faces, or upload a photo of your signature and let the white background drop out. Place it: it lands in the middle of the page as a stamp you drag into position and resize by its corners. Tick Remember and the signature is kept in this browser's storage for next time — up to four. Stamp adds APPROVED, RECEIVED or your own words with today's date beside it. Save writes the file; the signature is a standard stamp annotation that every reader shows and prints, and Flatten the comments (More menu) bakes it into the page content so it can no longer be moved.
Questions
Is this a legally valid electronic signature?
It is an image of your signature placed on the document, which is what most e-sign tools produce and what many agreements accept; it is not a certificate-based digital signature. Whether it binds depends on your jurisdiction and the counterparty.
Can others move or remove my signature?
As a stamp annotation, yes, in an editor. Flatten the comments into the pages before sending, and the signature becomes part of the page like any other ink.
Is my file uploaded?
No. Everything runs in your browser — pdf.js draws the document and pdf-lib rewrites it in a background thread — and Save writes to your disk or downloads a copy. Nothing leaves your device.
