Common Bihar Police upload errors, and the fix
Photo over 25 KB
Bihar Police refuses a photo above 25 KB (the allowed range is 15–25 KB). Phone photos are usually 2–5 MB, so compress it to around 20 KB rather than right at the limit.
Wrong photo size or shape
The Bihar Police photo should be 3.5 × 4.5 cm (276 × 354 px at 200 DPI). A photo in a different shape gets squashed or refused, so crop it to that shape before shrinking; the tool above does both.
Signature over 25 KB
Bihar Police refuses a signature above 25 KB (the allowed range is 15–25 KB). Phone photos are usually 2–5 MB, so compress it to around 20 KB rather than right at the limit.
Signature under 15 KB
A clean signature on white paper is often only a few KB, below the 15 KB minimum for Bihar Police. FitMyKB raises the quality first and then adds invisible padding, so the file reaches 15 KB without changing how it looks.
Wrong signature size or shape
The Bihar Police signature should be 4 × 2 cm (315 × 157 px at 200 DPI). A signature in a different shape gets squashed or refused, so crop it to that shape before shrinking; the tool above does both.
Background isn't plain white
Bihar Police wants a plain white or light background. A coloured wall, curtain or room behind you can get the photo rejected at verification, weeks later. Turn on White background and it's replaced for you.
Not a real JPG
The Bihar Police portal takes JPG files. iPhone photos are HEIC and screenshots are PNG, and renaming a file to .jpg doesn't convert it. Drop the original into the tool: it always saves a genuine JPG.

Tips for Bihar Police
CSBC asks for two signatures, one in Hindi and one in English, uploaded separately, and a photo not older than two months. Both files must land in a narrow 15–25 KB band.
