Frequently Asked Questions

Is my PDF or signature uploaded? +

No. Preview, signature creation, placement, and PDF export happen locally in your browser.

Is this a digital certificate signature? +

No. It adds a visual electronic signature image and does not create a certificate-backed cryptographic signature.

Can I sign several pages? +

Yes. Enter all or a custom range such as 1-3, 5.

Can I use a transparent signature image? +

Yes. A transparent PNG generally produces the cleanest result.

Does signing flatten the PDF? +

No. Original text and vectors stay intact; the signature is added as a separate image layer.
