Draw your signature with your mouse or finger, then place it anywhere on any page of your PDF. Download the signed document instantly — no upload, no account, no printing.
Printing, signing, scanning and re-uploading a document just to add a signature is slow. This tool lets you draw your signature once with a mouse or finger, then places it directly onto the PDF page as an image layer — no printer required.
The signature pad captures your drawing as an image, and pdf-lib embeds that image onto the chosen page at the chosen position. Everything happens in your browser — your document is never uploaded, which matters for contracts and private paperwork.
Open the tool, choose your PDF, draw your signature in the signature pad (mouse on desktop, finger on mobile), choose the page and position, then click Add Signature. The signed PDF downloads immediately.
This creates a visual signature image placed on the document — suitable for informal agreements, forms, and internal paperwork. For legally binding e-signatures with audit trails and certificates, use a dedicated e-signature service.
Yes — draw your signature with your finger directly on the touchscreen; it works the same as a mouse on desktop.
Yes, before placing you can choose the page number and general position (like bottom right), and adjust the signature size with the size slider.
No. Your signature and PDF are combined entirely inside your browser. Nothing is uploaded to any server.
