Reducing a JPG/PNG to 20KB without losing visible quality is a common challenge—especially for government forms, online applications, competitive exams, and digital submissions that require strict file size limits.
The good news? You can compress your images to 20KB while keeping them clear and professional—if you use the right method.
In this guide, we’ll show you:
- How to convert JPG/PNG to 20KB easily
- Why some images lose quality
- The correct compression settings
- How to reduce image size on mobile and PC
- The fastest online tool for 20KB compression
Let’s start.
What Does “20KB Image Size” Actually Mean?
20KB is an extremely small file size.
Most photos taken on a phone range between 1MB–5MB (1000KB–5000KB).
To shrink that to 20KB, you need:
- Smart compression
- Reduced dimensions
- Efficient file format
BUT — if done correctly, the visible quality will remain almost the same.

Why Images Lose Quality During Compression (Explained Simply)
When reducing image size to 20KB:
1. Too much data is removed
Aggressive compression reduces clarity.
2. PNG images are heavier
PNG uses lossless compression → harder to shrink.
3. Large dimensions take more storage
A 4000×3000px image will NEVER reach 20KB without resizing.
