Frequently Asked Questions

How does client-side PDF signing work?

When you draw your signature on the interactive canvas pad, your browser captures the vector strokes as a transparent PNG in memory and embeds it directly into your PDF document using client-side JavaScript. The file never leaves your device.

Are my signature and confidential documents safe?

Yes, 100%. Because all drawing and PDF modifications happen locally in your browser memory, your signature and sensitive documents are never transmitted to our servers or stored in any database.

Where will my signature appear on the PDF?

By default, your drawn signature is embedded at the bottom of the final page of your document, which is the standard placement for contracts, agreements, and approvals.

Can I draw my signature using a phone or tablet touchscreen?

Yes. The signature pad is fully optimized for touch gestures, allowing you to draw smooth signatures with your finger or stylus on mobile devices, iPads, and touch-enabled laptops.

Do you charge fees or require an account to sign PDFs?

No. Our e-signature tool is completely free to use without subscriptions, watermarks, page limits, or account registration.

Does signing a PDF affect text clarity or formatting?

No. The signature is embedded as a high-resolution transparent overlay without modifying original document fonts, vector layouts, or image quality.
