pdfsignpad.com is built and run by ZIX DEV Inc. The easiest way to reach us is email: contact@zixdev.com. We read every message.

1. What to contact us about

• Support — a tool isn't working, a signature won't place, or a PDF won't open. We can't see your document or signature, since neither ever leaves your device — tell us which browser you used and what happened; a screenshot helps.
• Feedback and ideas — suggestions for new tools or improvements are always welcome.
• Questions about whether a simple e-signature suits your document — this isn't legal advice; see our Disclaimer for what a simple electronic signature is and isn't.
• Privacy and data requests — the process for access, deletion, and other data-subject requests is set out in our Privacy Policy, including how quickly we respond.
• Legal notices — send formal notices by email or to the mailing address below.

2. By mail

Email is much faster — postal mail is best kept for formal legal correspondence.

3. When you'll hear back

We're a small team, so we can't promise a fixed response time — but we aim to reply within a few business days. Privacy requests follow the statutory timelines described in the Privacy Policy.

4. Before you write

Common questions — whether your document is uploaded, how saved signatures work, size limits, signing on your phone — are already answered on our FAQ page. It's worth a quick look first.
