Guide • Updated: 2026-11-11 • Free, in your browser — your photos are never uploaded
Every exam form asks for a photo — and almost every form asks for a different file size. One notification says 20 KB, the next says 50 KB, another allows 100 KB. Upload the wrong size and the form rejects your photo, sometimes without telling you why.
This guide explains the three limits you will see most often, how to find out which one your form wants, and how to hit it exactly.
20 KB — the strict limit. Many SSC and bank recruitment forms cap the photo at 20 KB. These are the hardest to hit, because a sharp colour photo is naturally bigger than 20 KB. You need proper compression, not just a smaller image.
50 KB — the common limit. NEET, JEE and most NTA exams accept photos between 20 KB and 50 KB. This is the most forgiving of the three: a well-taken 35×45 mm photo at 300 DPI usually fits after one round of compression.
100 KB — the generous limit. Some university and state-level forms allow up to 100 KB. If your form says 100 KB, do not over-compress — a 60–90 KB photo will look much sharper than a 20 KB one, and it still passes.
Before you resize anything, open the official notification, information bulletin or admit-card instructions for your exam and find the photo section. It will state the dimensions, the KB range and the background colour. Write those numbers down — they are the only ones that matter for your form.
Take a fresh photo against a white or light background, in bright even light, with your face covering about 80% of the frame and both ears visible. A good original compresses cleanly; a dark or blurry original turns to mush the moment you shrink it.
Open ResizeHub’s Exam Photo Resizer, upload your photo, and set the dimensions to 35×45 mm (413×531 px). Then type in the KB limit from your notification — 20, 50 or 100 — and let the tool compress the file to fit. It adjusts the quality step by step until the file lands under your limit.
Check the downloaded file: its size should be inside your form’s range, the face should still be sharp when you zoom in, and the background should be white or light. If the file is under the limit but looks blurry, start again from the original photo instead of compressing the same file twice.
Remember the order: notification first, good photo second, exact KB target third. Do it that way and your exam photo will be accepted the first time. Everything is processed in your browser — your photo is never uploaded.
