Understanding File Size Problems
Many students face problems when their signature file size is either too small or too large. Here is how to fix these issues:

|---|---|---|
| File size less than 10 KB | Image quality is too low, or the image is too small | Increase scanner resolution or take a larger signature |

| Blurry signature | Low scanner resolution or shaky camera | Rescan at 200 DPI or retake the photo in good lighting |

- Wrong format: Save as JPG or JPEG. Anything else won't work.
- Blurry Signature: A blurry signature cannot be verified. Always ensure clear scanning or photography.
Tools to Adjust File Size
Free Tools You Can Use:
