Bihar Police Photo and Signature Size Maker
Bihar Police constable recruitment runs through the CSBC, which holds several separate constable drives, from general duty to the special branch, driver, and prohibition posts. The catch is that the photo and signature limits differ between these streams, so the numbers from one advertisement may not fit another.

What CSBC asks for
The Central Selection Board of Constable, the CSBC, recruits constables across general duty, special branch, operator, driver, and prohibition roles, often in very large cycles of tens of thousands of posts. Each advertisement sets its own upload rules.
A photo of about 3.5 by 4.5 cm and a signature of about 4 by 2 cm are commonly cited, both as JPG on a white background, the signature in black or blue ink. File sizes vary by stream, often around 20 to 50 KB for the photo, though some drives like the special branch use a tighter 15 to 25 KB.
Because the figures shift between advertisements, read the photograph and signature instructions in the exact CSBC notice you are applying under rather than reusing an old number.
Match your CSBC stream
Find your advertisement's limits, then resize the photo to a passport shape and compress to a KB size so it fits the window, and size the signature the same way. The compress tool outputs JPG, which CSBC expects.
Some streams, such as the special branch, have asked for the signature in both Hindi and English as separate files, so check whether yours needs one or two. Sign in running hand on white paper, not in capitals.
If a file lands under its floor, increase a too-small file to clear it. The tool resizes and compresses only and cannot change a background.
