Tips for Signing PDFs

Sign on a white background — if uploading a signature image, make sure the background is clean for a professional result.
Add initials too — for multi-page contracts, add initials to each page to confirm you've read them all.
Fill in form fields first — if the PDF has text fields or checkboxes, complete those before signing.
Protect after signing — consider adding a password to the signed PDF to prevent future edits.
Password-protected PDF? — unlock the PDF before signing if the document is locked for editing.

Common Questions

Is an electronic signature legally binding? For most personal and business documents — contracts, consent forms, agreements — electronic signatures are legally valid under laws like the US ESIGN Act and EU eIDAS regulation. For notarized or government documents, check specific local requirements.

Can I sign on my phone? Yes. PDF Genie works in mobile browsers. The draw method works particularly well on smartphones and tablets with touch screens.

Can I add a date or initials as well? Yes. After placing your signature, you can add additional text elements such as your printed name, date, or initials at any location on the document.
