Best Free Signing Tool Out There

Frequently Asked Questions

Get instant answers to common questions about our PDF Signature tool.

Is it safe to upload my documents to sign them?

Yes, it is 100% safe. Your privacy is our top priority. The entire signing process happens locally in your browser. Your files are never uploaded to our servers, ensuring your data remains completely private.

Are electronic signatures legally binding?

Electronic signatures are widely accepted and legally recognized in many countries, including the U.S. (ESIGN Act) and the E.U. (eIDAS Regulation). However, the legal validity can depend on the type of document and local jurisdiction. For critical legal matters, we recommend consulting a legal professional.

Can I add text, like the date, along with my signature?

Absolutely. Select the "Text/Stamp" element type. You can add any custom text, including names, dates, or notes. You can also use pre-built stamps. Position and style the text just like you would a signature.

What is the difference between Draw, Type, and Upload?

Draw: Use your mouse or a touchscreen to draw your signature freehand for a unique, personal touch.
Type: Enter your name, and our tool will render it in several stylish, signature-like fonts for you to choose from.
Upload: If you already have a picture of your signature (e.g., a transparent PNG), you can upload it directly.

What happens to my file after I'm done?

Since your file is never uploaded, it remains on your computer. The signed PDF is generated in your browser, and you download a new copy. We never see, access, or store your original or signed files.
