Sign PDF Online Free

Signing PDF documents should not require downloading expensive software or creating accounts. Our online PDF signing tool runs entirely in your web browser — there is nothing to install, no plugins needed, and no signup required. Simply upload your PDF, create your signature using one of three methods (draw, type, or upload), position it on the page, and download your signed document. The entire process takes less than a minute. The tool uses HTML5 canvas technology for smooth signature drawing, producing natural-looking signatures even with a mouse. On touch devices like tablets and phones, you can draw with your finger for an even more natural signature. The signed PDF maintains all original content and formatting — your signature is added as a visual overlay without altering any existing elements. This makes it ideal for everyday signing tasks: rental agreements, permission slips, vendor forms, employment documents, and more.
