How do I reduce a photo from MB to KB?

Drop it in above and set the target in KB. A 4MB phone photo typically becomes 30–50KB at passport size with no visible loss.

Can I set exact pixel dimensions?

Yes — enter width and height. The tool keeps those exactly and only adjusts quality to hit the KB limit.

Common image limits on Indian exam forms

SSC and IBPS ask for a photo of 20–50KB and a signature of 10–20KB. IBPS also asks for a left thumb impression (20–50KB) and a handwritten declaration (50–100KB). NTA exams accept photos of 10–200KB.

Always confirm in the current notification — and remember that going under the minimum is a rejection too.
