RRB Photo Upload — 20 KB to 300 KB

Railway Recruitment Board — Indian Railways requires the photograph to be between 20 KB and 300 KB. A range is harder than a ceiling: compress too aggressively and the file falls under the floor and is rejected for being too small. Dimensions must fall between 550 × 550 px and 1000 × 1000 px. Accepted format: JPEG.

Worth knowing

24-bit colour depth required. Plain white background, three quarters of the photo showing the full face from the top of the hair to the bottom of the chin, taken within 10 days of the application, with the candidate's name and the date of the photo captioned at the bottom. RRB runs about 21 regional boards and each Centralised Employment Notice republishes its own upload notice, so figures can vary slightly by CEN — check yours.

How to get your file to fit

  1. Drop your photo into the tool above. The target is already set to 300 KB with a 20 KB floor.
  2. Press compress. The tool searches for the highest quality that still fits, rather than picking a quality and hoping — so you keep as much detail as the limit allows.
  3. Check the reported size and dimensions against the table above before you upload. If the tool had to reduce the dimensions to reach the target, it says so.
  4. Download and upload to RRB. Keep the original file — if the portal rejects the upload for a reason other than size, you will want to start again from the full-quality image.

RRB upload questions

How do I get my file under 300 KB without ruining it?

By searching for the right JPEG quality rather than guessing at one. The tool above encodes your image repeatedly at different quality settings and keeps the largest result that still fits — so you spend every available byte on image quality instead of overshooting and handing in something blurrier than it needed to be.

If no quality setting is small enough, it reduces the dimensions in steps and searches again, and it tells you when that happened.

My file is under 20 KB. Is that a problem?

Yes — RRB sets a floor as well as a ceiling, and an upload below 20 KB can be rejected. Set the minimum field in the tool and it will keep the file inside the window. If your image is small and flat, it may not contain enough detail to reach the floor at all; increasing the dimensions before compressing usually fixes that.

Is my file uploaded to a server?

No. Everything runs in your browser. This site is static files on a CDN with no upload endpoint at all, which is also why it is free — there is no bandwidth bill to pass on.

Can I upload a PNG or a HEIC instead?

RRB lists JPEG, so convert first. Drop a PNG or an iPhone HEIC into the tool above and choose JPEG as the output — it will be decoded and re-encoded in one step. PNG is also a poor fit for a KB target: its quality setting does nothing, so the only way to shrink a PNG is to make it smaller in pixels.

Why does the size shown differ slightly from what the portal reports?

Because "KB" is ambiguous. This tool uses 1 KB = 1024 bytes, which is what upload validators almost always use. Some file managers use 1 KB = 1000 bytes, which makes the same file look about 2.4% larger. If you are right on the edge of a limit, aim a few KB under it.
