What is 10KB Image? How to Compress Photo to 10KB or Less

When a portal asks for an image under 10KB, they are usually talking about your Signature or Left-Hand Thumb Impression. While 10KB sounds tiny, it's the standard for millions of Indian government applications.
The Quality Tradeoff
At 10KB, the "compression artifacts" become visible. This means you'll see small blocks or blurriness around sharp edges. To counter this for signatures:
- Scan at 200 DPI: Higher DPI with low quality is better than low DPI with high quality.
- Grayscale is Better: If the portal allows, grayscale images have smaller file sizes than color images of the same quality.

Frequently Asked Questions
Is 10KB too small for a clear signature?
It is small, but if you use a black pen on a white background and high contrast, a 10KB JPG is perfectly legible for portal verification.
Can I convert a photo to 10KB?
You can, but a full passport photo at 10KB will look very pixelated. It is best reserved for signatures and thumb impressions.
