Why Exam Forms Reject Photos and Signatures
Application portals for SSC, IBPS, UPSC, and Railways enforce hard file-size and dimension checks before allowing submission. A file even 1 KB over the maximum, or a few pixels off the required dimensions, gets rejected outright — often with no explanation beyond a generic error message. This is one of the most common reasons candidates lose precious time on submission day, sometimes right before the deadline closes.
The trap is that a generic photo editor or WhatsApp compression usually gets the KB size roughly right while completely ignoring the exact pixel dimensions the form expects — and most portals check both independently.
Pixel Dimensions
Exact width × height the form expects, checked separately
File Size Range
Minimum and maximum KB — both ends can fail you
Format
Almost always JPG — PNG and HEIC get rejected outright

Reducing File Size Without Losing Quality
The correct order matters more than most people realize: resize to the exact target pixel dimensions first, then compress using JPEG quality reduction — not the other way around. Shrinking a photo that's already been heavily compressed at full resolution produces a blurrier result than compressing a properly sized image from the start, since the two operations interact differently depending on their order.

Frequently Asked Questions
Common reasons include exceeding the maximum KB, dimensions not matching the form's expectation, or falling below the minimum KB required. Match both pixel dimensions and KB range exactly.
The photograph must be 275×354 pixels between 20-50 KB in JPG format. The signature must be 236×79 pixels between 10-20 KB in JPG format.
A photograph of 200×230 pixels between 20-50 KB, and a signature of 140×60 pixels between 10-20 KB, both in JPEG format.
No strict pixel dimension — only file size (20-200 KB) and JPG format are mandatory. The signature must be 350-500 pixels and 20-100 KB, showing three signatures scanned together.
Resize to the exact required pixel dimensions first, then compress using JPEG quality reduction — this keeps the image sharper than shrinking an already-compressed large file.
3.5 cm × 4.5 cm, roughly 413×531 pixels at 300 DPI. Always confirm the exact requirement in the specific form's notification.
