At A Glance (Key Takeaways)
- Signatures for online exams must typically be 140 × 60 pixels and between 10KB and 20KB.
- Shooting a photo of your paper signature on a dark desk creates unwanted gray shadows that bloat file size.
- Cropping tightly around the signature ink is the single most effective trick to reduce file weight.

How to Take a Clean Signature Photo with Your Phone
1. Use a dark blue or black gel/ballpoint pen on clean, unlined pure white paper.
2. Place the paper directly under a desk lamp or outdoors in daylight to eliminate mobile phone shadows.
3. Snap a clear photo from directly above.
4. Open PixEnhance Image Resizer, crop closely around your autograph, and set the target size to 15KB.

Frequently Asked Questions
Why does the portal say signature is too small (under 10KB)?
Portals reject files under 10KB to ensure signatures are not illegible. On PixEnhance, you can dial the slider up to 14KB-18KB to sit comfortably inside the allowed 10KB-20KB range.
