Questions
How do I take a good signature photo?
Sign in black or dark blue ink on plain white paper. Photograph it in daylight from directly above, without your shadow on the page. Fill most of the photo with the signature.
My signature looks too thin or broken. What do I do?
Move the ink sensitivity slider to the right. That keeps lighter strokes. If grey shadows appear instead, move it back to the left.
Why is my file under the minimum KB?
Signatures are simple images, so they compress very small. FormFit adds a blank comment block inside the JPG to reach the minimum. The picture doesn't change.
Is my signature uploaded anywhere?
No. It's processed in your browser and never leaves your device.
