Exam portals often require a passport-style photo and sometimes a signature image. Requirements may include pixel dimensions, background color and file-size limits. Below are practical steps and common targets used by many Indian exam portals.
Common checks for exam portal uploads
- File format: JPEG / JPG is accepted almost everywhere. PNG rarely required for photos, but used for signatures with transparency.
- File size (typical): many portals accept ≤100 KB to 200 KB for photos. Some accept up to 500 KB. Always read the portal guidance.
- Pixel dimensions: many portals ask for 350 x 450 px, or 200 x 200 px for small thumbnails. When in doubt, 350 x 450 px is a safe starting point.
How to prepare your image
- Crop to the required ratio (usually portrait 3:4 or square if requested).
- Resize to the portal pixel size (e.g. 350 x 450 px) using an editor or Compressly (downscale option).
- Use JPEG output and a target KB (start with 100 KB). Compress, then preview and upload to the portal.
- If the portal rejects, slightly lower the target KB or crop tighter and try again.
Practical tip: Keep an unchanged original copy. Create one compressed copy for upload and
one slightly larger copy in case the portal requires a higher-quality image later.

FAQ
Q: I uploaded a 100 KB photo and it was rejected. Why?
A: Some portals check pixel dimensions, aspect ratio, or background color as well.
Confirm pixel dimensions and background (white or light) and try again.
Q: Should signature be PNG or JPG?
A: If the portal requires a transparent signature, use PNG. If transparency is not
required, JPG is usually smaller and safe.
