Need to sign a PDF today? Printing, signing with a pen, and scanning is slow — and the scan often looks worse than the original. A free tool to sign PDF online keeps the file digital end to end.
With PDFCAN you can add a signature to a PDF three ways: draw with mouse or trackpad, type your name in a script style, or upload a PNG/JPG of your signature.
How to sign a PDF online: open the editor, choose Sign, create or upload the signature, place it on the signature line, resize if needed, then Export. The signed PDF downloads to your device.
Electronic signature vs wet ink: for many contracts and HR forms, a clear signature image on the PDF is accepted. Always follow your organization’s policy for legally binding e-sign (DocuSign-style workflows differ from a simple signature stamp).
Privacy tip: prefer an in-browser sign PDF free tool that does not require an account for basic signing. PDFCAN keeps processing local by default.
Fair use still applies (10 PDFs/day, 100 pages). Signing and exporting within that limit are free and watermark-free.
