Reduce any JPG, PNG or WEBP photo to exactly 20KB — instantly, privately, with no server upload. For the strictest government portals and exam registration systems.
Supports JPG, PNG, WEBP · Up to 20 images at once
20KB is one of the strictest file size limits used by government portals and exam registration systems. Here are the most common situations:
| Use Case | Typical Size Limit | Recommended Target |
|---|---|---|
| State government exam portal (photo) | 10–20 KB | 20 KB |
| Signature image upload | 10–20 KB | 20 KB |
| Older UPSC/SSC registration systems | 20 KB max | 20 KB |
| Railway recruitment board (RRB) | 10–40 KB | 20 KB |
| State police recruitment portal | 10–20 KB | 20 KB |
| Municipal corporation forms | 20 KB max | 20 KB |
Government portals that require 20KB images were typically built on older infrastructure with limited server storage and bandwidth. These systems store millions of applicant photos, so keeping each file small reduces storage costs significantly. While modern systems have moved to 100KB or 200KB limits, many legacy portals still enforce the 20KB limit.
20KB is a very small file size for a photo. Here's how to maximize quality:
If your portal requires a photo of 200×230 pixels, resize your image to exactly those dimensions before uploading to this tool. A 200×230px image at 20KB will look much better than a 1000×1000px image compressed to 20KB, because the compressor doesn't need to throw away as much detail.
Plain backgrounds compress extremely efficiently in JPEG format. A photo with a white background at 200×230px can easily fit in 20KB while keeping the face sharp.
Well-lit photos with even illumination compress better than dark or unevenly lit photos. According to Google's image compression research, images with less noise and more uniform areas achieve significantly better compression ratios.
