## FAQ

### Do scanned forms work?

Pure scanned forms may need overlays (Add text / Sign PDF) instead of AcroForm fields. Fill & sign works best with fillable PDFs.

### Is the signature a legal certificate?

No. It is a visual signature stamp drawn in the browser — not a cryptographic digital signature.

### How do I lock filled values?

After filling, use Flatten forms so field values can no longer be edited.
