Frequently Asked Questions

Can I type or upload a signature instead of drawing it?

Yes. Choose Draw, Type, or Upload in the tool — typed signatures render in a natural handwriting-style font, and uploaded signatures accept any PNG or JPG image.

Where does the signature get placed on the page?

In the bottom-right corner of whichever pages you choose — all pages, just the first, or just the last.

Is this a legally binding signature?

FormatDog applies your drawn signature as an image onto the PDF. Whether that meets legal requirements for a specific document depends on your jurisdiction and use case — for contracts requiring certified e-signatures, check your local regulations first.

Is my file uploaded anywhere?

No. The entire signing process, including drawing your signature, happens locally in your browser.

Is this free?

Yes, completely free with no daily limits.
