Why signature size matters
A signature image should fit naturally inside the signature area without looking stretched or blurry. Balanced dimensions make forms feel cleaner and more professional.
Good signature image practices
- Use a clean background or transparency when needed
- Keep the aspect ratio consistent
- Avoid oversharpened or low-resolution scans
- Export at a practical size instead of full-screen size
PNG or JPG?
PNG is usually better when you need transparency. JPG is more suitable when you want a smaller file size and the background does not matter.
