Tips for a clean signature
- Sign slowly and use a larger canvas if you can. A phone held sideways gives you more room.
- Keep the signature on the line and away from the printed text.
- Check every page in the preview before you send the file.
- Save the signed file under a new name so you keep the original.
Is an online signature valid?
In the United States, electronic signatures are generally given legal effect for many ordinary documents under federal and state law. Some documents have special rules, such as certain wills, court papers and notices, and some businesses require a specific signing service. This is general information, not legal advice, so check the requirements for your document.
It helps to know the difference between two things:
- A signature image placed on a PDF, which is what a simple signing tool does.
- A certificate-based digital signature, which also proves the file was not changed after signing and is used in more formal workflows.
What you can sign
Contracts, rental agreements, forms, permission slips, invoices, delivery notes and quotes are common examples. If a document needs a witness, a notary or a certificate-based signature, a simple online signature may not be enough.
