Quick answer
Most NTA exams (NEET, JEE, CUET, UGC NET) want a JPG photo around 10–200 KB and a signature 4–30 KB. Bank exams (IBPS/SBI) want a smaller fixed-pixel photo ~20–50 KB at 200×230 px. Prepare each on your device with TryQuickImg — convert HEIC, resize to the pixels, compress under the KB cap — not uploaded to our servers for processing.

ID document photo sizes
Not exams, but the same prep pipeline — crop, resize to the pixels, compress under the KB cap, all on your device.
| Document | Authority | Photo | Notes |
|---|---|---|---|
| Aadhaar | UIDAI | No upload — captured in person | A photo change is a biometric update done at an enrolment centre |
| PAN card | Protean (NSDL) / UTIITSL | Set by the portal — check before you upload | Signature is uploaded separately |
UIDAI and the PAN portals set their own current limits (and differ between enrolment, update, and online correction flows) — always confirm on the official portal before uploading.
How to prepare any exam photo (no upload)
- Convert HEIC → JPG if it is an iPhone photo — many portals reject HEIC. HEIC to JPG.
- Resize to the requested pixels (e.g. 200×230 for bank exams). Resize image.
- Compress under the KB cap — pick the target and download. Compress image.
- Prepare the signature the same way — crop tight, compress to ~4–30 KB.
Common reasons a photo is rejected
- The file is HEIC (from an iPhone) and the portal only accepts JPG.
- The file is over the KB limit — compress it down.
- Wrong pixel dimensions — resize before you compress.
- Busy or dark background — use a plain, light background.
- Signature scanned in colour or too faint — black ink on white, cropped tight.

Frequently asked questions
What is the most common exam photo size?
For NEET and JEE Main the current Information Bulletins state a JPG photo of 10–200 KB and a signature of 10–100 KB. Bank exams (IBPS/SBI) are smaller and fixed-pixel: photo ~20–50 KB at 200×230 px, signature ~10–20 KB at 140×60 px. SSC no longer accepts an uploaded photo at all. Always confirm the official notice.
What size should a signature scan be for exam forms?
Signatures are usually the smallest file: roughly 4–30 KB as JPG, black ink on white paper. Bank exams often specify 140×60 px. Scan or photograph it, crop tightly, then compress to the required KB.
Why does my exam photo get rejected?
Most rejections are format or size: an iPhone HEIC file the portal cannot read, a file above the KB cap, wrong pixel dimensions, or a busy background. Convert HEIC to JPG, resize to the requested pixels, then compress under the KB limit.
Are these sizes official?
These are commonly-cited ranges to help you prepare — the exact numbers change by exam cycle and are set by the conducting authority. Always verify the current official information bulletin or portal before you upload.
