Why photographs get rejected for RRB NTPC
- Background not white — RRB is stricter about this than most boards
- File smaller than 20 KB — portals reject under-sized files, not only over-sized ones
- Photo stretched to reach the pixel dimensions, distorting the face
- Cap, hat or tinted glasses obscuring the face
- Busy or dark background instead of a plain light one
- A photograph of a printed photograph rather than a digital original
Frequently asked questions
Why do other tools make my photo blurry at this size?
Most reach a small file by dropping JPEG quality until the image falls apart. This one reduces resolution in gradual steps, restores edge definition afterwards, and searches for the highest quality that still fits the limit — so it keeps far more detail at the same file size.
Does this tool upload my photo anywhere?
No. Cropping, resizing and compression all run inside your browser using the Canvas API. The image never leaves your device — you can disconnect from the internet after the page loads and the tool still works.
Need your signature too?
Most portals ask for a signature in the same session, with a different size limit from the photograph.
