Open Image Compressor →Why Do Forms Ask for Images Under 20KB?
Government portals, exam boards, and job portals set a 20KB limit for a few practical reasons:
- Server load — small files are faster to upload and store in bulk
- Slow connections — many applicants use mobile data or 2G/3G networks
- Storage cost — portals store millions of applications, so small files add up
- Legacy systems — older government systems often have hard file size limits
The most common portals requiring images under 20KB include UPSC, SSC CGL/CHSL, IBPS, Railway RRB, and various state PSC applications.
Step-by-Step: Compress Image to 20KB
Open CompressPic Image Compressor
Go to compresspic.in/compress. No account or login needed.
Upload Your Image
Click the upload area or drag and drop your JPG, PNG or WebP photo. Your image is never sent to any server — it stays on your device.
Set Target Size to 20 KB
After upload, enter 20 in the target size field and make sure KB is selected.
Click Compress Image
CompressPic uses a binary search algorithm to find the highest quality that still fits under 20KB. It takes just a few seconds.
Check Before/After and Download
You will see the original size vs compressed size. If the target was met, click Download to save your compressed image.
What If the Image Still Won't Go Below 20KB?
This happens when the image has very high resolution or complex detail. Here is what to do:
- Resize first — use the Image Resizer to reduce dimensions to 275×354px or 413×531px (standard form sizes), then compress
- Crop tightly — remove unnecessary background before compressing
- Use JPG format — if your photo is PNG, convert it to JPG first, then compress. JPG compresses much smaller than PNG for photos
