RRB's photograph is landscape, and almost nobody expects that
Every other board in this list asks for a portrait photograph. RRB asks for 320 × 240 pixels — wider than it is tall. People bring a normal passport photo, an ordinary resizer squashes it to fit, and the result is a visibly compressed face that gets flagged at document verification rather than at upload.
Here the photograph is cropped from the centre to 4:3 instead, so the proportions of the face are preserved and the top and bottom of the frame are what get trimmed. That means you want a photograph with a little room above the head to give away — a very tight portrait crop will lose the top of your hair when it becomes landscape.
The signature floor is unusually high
RRB asks for a signature of 140 × 60 pixels between 30 and 55 KB. Look at those numbers together: 140 × 60 is 8,400 pixels, and 30 KB is a great deal of data for an image that small. A normal ink-on-paper signature encoded at that size lands somewhere around 4 to 8 KB, comfortably under the floor.
This is why RRB signature uploads fail so often, and why the usual advice — "compress it" — makes it worse. The fix is to make the file bigger without changing the picture, which is exactly what happens here: the file is padded with a JPEG comment block, a segment the standard defines and every decoder ignores. The signature is pixel-for-pixel what it was; the file weighs 30 KB.
Plain white, not "light"
RRB specifies a plain white background rather than a light one. A photograph taken against a cream wall or a curtain will usually pass the automated check and can be questioned later. If your background is not white, the background colour tool will replace it cleanly before you resize.

Common questions
Why was my photo rejected when it was under the size limit?
Almost always because it was under the minimum instead. SSC asks for 20–50 KB, so a 12 KB photo fails. Portals rarely say which end you missed. This tool checks both.
Does padding the file to reach the minimum damage the photo?
No. The padding is a JPEG comment segment, which is part of the format and is skipped by every decoder. The pixels are bit-for-bit identical to the unpadded version — only the file size changes.
Which preset should I use for NEET?
NTA — passport photo, for the main upload. NEET also asks for a 4 × 6 inch postcard photograph, which has its own page: the postcard photo maker.
Can I use a PNG or a screenshot?
Drop in anything and you get JPG back, which is what UPSC and NTA require. They refuse PNG and PDF outright at the upload step, so converting first is not optional.
My photo is smaller than the required size — is that a problem?
You are told when it happens. The image is enlarged so the portal accepts it, but it will look soft, and it is the same photo that gets printed on your admit card and checked at the exam centre. A higher-resolution original is worth finding.
Does the exam board also require my name and the date on the photo?
NTA does, for NEET and JEE. Several state boards do too. Use the add name and date tool first, then bring the result back here to hit the size window.
