Common Errors When Photo Exceeds 20KB
File size exceeded
The exam portal shows this when your photo is larger than the maximum allowed size.
Invalid image format
Some portals only accept JPG/JPEG. PNG files are often larger and get rejected.
Dimensions incorrect
Even with correct file size, wrong pixel dimensions (width × height) cause rejection.
Photo too blurry after compression
Over-compressing a large photo makes it unreadable. Start with correct dimensions first.
Frequently Asked Questions
Why do government exams require photos under 20KB?
Exam portals have strict file size limits to handle millions of applications simultaneously. A 20KB photo loads faster during verification and reduces server load. Most SSC, IBPS, and Railway exams set 20KB as the minimum for signatures and sometimes for photos.
Will compressing to 20KB make my photo blurry?
If your original photo is a standard passport-size image (3.5cm × 4.5cm), compressing to 20KB maintains acceptable quality. The key is starting with the correct dimensions — a 4000×3000 pixel phone camera image compressed to 20KB will look bad, but a properly cropped 200×250 pixel passport photo at 20KB looks fine.
Does my photo get uploaded to any server?
No. ReadyToSubmit processes everything inside your browser using JavaScript. Your photo never leaves your device. This is especially important for Aadhaar-linked exam photos.
Can I use this on mobile?
Yes. The tool works on Chrome, Safari, and any modern browser on both Android and iPhone. No app download needed.
