Understanding digital signatures
A digital signature isn’t just a scribble on a PDF. It’s cryptographic proof that a file hasn’t been changed.
The moment you sign, the system creates a unique fingerprint of the document. If anyone edits even one character after that, the signature breaks.
Free tools that actually work
People aren’t waiting anymore. If your signing process requires printing, scanning, or installing apps, you’ve already lost their attention.
Free online tools let anyone create a digital signature online in seconds — upload, sign, send. No trials. No watermarks. No wasted time.
When signing fails
Sending a contract with a typed name or a pasted image might feel fine. Until someone disputes it.
And you have no audit trail, no metadata, nothing to show it was actually signed.
That’s where proper digital signature generators come in — they record timestamps, IP addresses, and the exact version of the file signed. No room for doubt.
Frictionless experience
You know the best experience? The one no one notices. No logins, no popups, no instructions.
Just upload a document and sign a PDF online in a way that fits modern workflows — especially for freelancers, remote teams, and anyone who needs things done now.
