Frequently Asked Questions
How do I sign a PDF for free?
Open your PDF, create a signature by drawing, typing or uploading an image, drag it onto the page where it belongs, then click Sign & download. The whole process is free and runs in your browser โ no account needed.
Is my PDF uploaded to a server?
No. The PDF is read locally and the signature is embedded entirely in your browser using JavaScript. Nothing is sent to any server, so your file and signature stay completely private.
Can I draw my signature with a mouse or touchscreen?
Yes. The Draw tab gives you a signature pad that captures pointer input, so you can sign with a mouse, trackpad, stylus or finger on a touchscreen, and pick a pen color.
Can I type my signature instead of drawing it?
Yes. The Type tab turns your name into a signature using a cursive or serif font of your choice, then renders it onto the page just like a drawn signature.
Can I upload an image of my real signature?
Yes. Upload a PNG or JPG of your signature on the Upload tab. A transparent PNG works best because the background stays clear when placed on the page.
Which page does the signature go on?
Use the Page number field to pick any page in the document. The preview updates so you can position the signature exactly where you want it before downloading.
Does the signature stay in place when I open the PDF elsewhere?
Yes. The signature is embedded directly into the PDF as an image at the chosen position, so it appears in the same spot in every PDF viewer, not just in this tool.
