Questions

Frequently asked questions

Is a signature created with this tool legally binding?

Electronic signatures have legal standing in many countries, but requirements vary by jurisdiction and document type. For specific legal cases, you should consult local regulations to ensure compliance.

Is my document sent to your server?

No, never. The entire process, from opening the PDF to adding the signature and generating the new file, happens within your web browser on your own computer. Your document's confidentiality is maintained because it never leaves your control.

Can I remove a signature after I add it?

No. Once you download the PDF, the signature is part of the page content and cannot be edited. To make a change, you must start over with the original, unsigned document.

Can I fill out other form fields in the PDF?

This tool is designed specifically for the task of adding a signature. It does not currently support filling out interactive form fields such as text boxes, checkboxes, or radio buttons. Its focus is on providing a secure way to sign a completed document.

What is the best way to create a signature?

It depends on your needs. Drawing is personal and unique. Typing is fast for informal documents. Uploading a high-resolution PNG image of your signature is best for professional use.

Background

The Convenience of Electronic Signatures

This tool lets you place a signature directly onto a PDF file. You can create your signature by drawing it, typing your name, or inserting an image.

  • Sign documents digitally to avoid printing, signing with a pen, and scanning. This saves time, paper, and ink, streamlining contract and approval workflows.
  • The signing process happens entirely in your browser, so your sensitive documents remain secure. Your private information stays on your own device.
