03 — Tips
Get a clean result
- Sign with a dark pen on plain white paper and photograph it flat, in daylight.
- Crop so the signature fills most of the frame; empty paper wastes the size limit.
- Replace the pixel size with your form's if it gives one, for example in cm at 300 dpi.
04 — Questions
Resize a signature to 20 KB: questions
How do I resize a signature to 20 KB?
Photograph or scan it, add it above, crop it, and press Fix & check. Maru saves a JPG of 20 KB or less.
What size should a signature image be?
It depends on the form. Many give dimensions in cm or pixels. Enter them in the rules panel; the 600 × 200 pixel start is just a common wide shape.
Can I use a photo of my signature from my phone?
Yes. Good light and a white background give the cleanest result.
