Frequently asked questions

Can I both fill out and sign a PDF in one step?

Yes. Add text fields for your name, address, and other information, then add your signature — all in the same session. Download the completed, signed form when you're done.

What signature options are available?

Type your name with a handwriting font, draw your signature freehand, or upload an existing signature image. All three methods produce professional results.

Will the recipient know it was signed electronically?

The signature appears as a visual element on the PDF. For formal e-signing with an audit trail, use SignForge's full e-signature feature — it's free too.

Need to send documents for signature?

Upload a PDF, place signature fields, send to anyone for signing. Free, legally binding, with a full audit trail.
