Sign Documents Without Printing, Scanning, or Uploading

The old way to sign a PDF is to print it, sign with a pen, scan it back in, and email a blurry photo. This tool skips all of that: draw your signature with a mouse or finger, or type your name in a handwriting-style font, then drag it directly onto the page. Everything โ€” reading the PDF, rendering it, and writing your signature back into it โ€” happens locally using the open-source pdf.js and pdf-lib libraries. Your document never touches a server.

Visual Signature, Not a Certified Digital Signature

To be upfront: this places an image of your signature onto the page, the same way signing with a pen and scanning would look. It does not create a cryptographically certified digital signature the way DocuSign or Adobe Sign do for legally-binding contracts. For everyday paperwork โ€” forms, internal approvals, letters โ€” that's exactly what's needed. For contracts requiring certified e-signatures, use a dedicated certified service instead.

Frequently Asked Questions

Does this e-signature tool upload my PDF anywhere?
No. The PDF is opened and rendered entirely in your browser, your signature is drawn or typed locally, and the signed PDF is generated locally too using the open-source pdf.js and pdf-lib libraries. Nothing is ever sent to a server.
Is a signature added this way legally binding?
This tool places a visual image of your signature onto the PDF page โ€” it does not create a cryptographic digital signature or certificate-based e-signature (like Adobe Sign or DocuSign do). For everyday documents (forms, letters, internal approvals) a visual signature is usually sufficient, but for contracts requiring legal certified e-signatures, use a dedicated certified e-signature service.
Can I sign multiple pages, or add my signature more than once?
Yes. Navigate between pages with the Prev/Next buttons and click "Place signature" on each page you need to sign. You can add as many signature instances as you like before downloading.
Can I resize or move my signature after placing it?
Yes โ€” drag the signature box to reposition it, or drag the small handle in its bottom-right corner to resize it, before you click Download.
What if I want to type my signature instead of drawing it?
Use the "Type" tab, enter your name, and pick from a few handwriting-style fonts. It's rendered as an image just like a drawn signature.
