Printing a document just to sign it and scan it back is a small daily waste of time. Electronic signatures remove that step entirely — and, done properly, they're just as legally valid as ink. Here's how e-signing works and how to do it in a couple of minutes.
Are e-signatures actually legal?
For the vast majority of everyday agreements, yes. In the United States, the ESIGN Act and UETA give electronic signatures the same legal weight as handwritten ones. The EU's eIDAS regulation does the same across Europe. Three things make an e-signature hold up: the signer intended to sign, they consented to do it electronically, and there's a record tying the signature to the document. A few high-stakes documents (some wills, certain property transfers) still require wet ink — check local rules for those.
How to sign a PDF
- Open the Sign PDF tool and upload your document.
- Create your signature — draw it with a mouse or finger, type it, or upload an image.
- Drag it onto the signature line and resize to fit. Add the date or initials if needed.
- Download the signed PDF. A tamper-evident audit trail is recorded automatically.
Why the audit trail matters
Anyone can paste a picture of a signature into a document. What makes an electronic signature defensible is the audit trail: a record of who signed, when, and proof the file wasn't changed afterward. If a signature is ever questioned, that trail is your evidence. A plain image has none of it — which is why a purpose-built e-sign tool is worth using over a photo-and-paste shortcut.
Requesting signatures from others
Signing your own document is step one. When you need a counterparty to sign, send them the file to e-sign the same way, then merge the signed pages back into your master record. Start signing now with Pdfblizz e-sign — it's ESIGN and UETA compliant and free to try.
