Frequently Asked Questions

Is my PDF uploaded to your servers?

No. Your PDF never leaves your device. Everything runs in your browser — nothing is sent to or stored on our servers.

Is the e-signature legally binding?

Electronic signatures created by drawing, typing, or uploading an image are widely accepted for everyday agreements. For documents requiring formal legal standing (e.g. contracts under the eSign Act in the US or eIDAS in the EU), you may also need a Certificate Authority-backed digital signature. Always consult a legal professional for high-stakes documents.

Is this free to use?

Yes, completely free. No account required, no watermarks, and no hidden charges.

Can I choose which page gets signed?

Yes. You can place the signature on the last page, the first page, all pages, or a specific page number of your choice.

What is the maximum PDF size?

You can sign PDFs up to 100 MB. Since all processing happens locally, there is no server upload time — even large files are handled quickly.

Which browsers are supported?

This tool works in all modern browsers — Chrome, Firefox, Edge, and Safari. No plugins or extra software needed.
