FAQ

Frequently Asked Questions

Is it free?

Yes. No signup required.

Is my file safe?

Yes — your PDF is processed entirely in your browser and never uploaded.

What if my PDF doesn't have fillable fields?

This tool only fills fields that already exist in the PDF — it doesn't add new form fields to a plain document. If none are found, you can still add a signature.

What field types are supported?

Text fields, checkboxes, radio buttons, and dropdowns.

Is the signature a legally binding e-signature?

No. This adds a visual signature image to your PDF — it isn't a certified, legally binding e-signature under eIDAS or the U.S. ESIGN Act, and there's no audit trail or certificate. For contracts that require legal certification, use a dedicated e-signature service.

Can I skip the signature and just fill fields?

Yes. Adding a signature is optional — leave "Add a signature" unchecked and just fill in the fields.
