What this tool solves
MBA applicants juggling internships compress CAT uploads incorrectly and miss deadlines. Pairing resize + KB targeting addresses both rejection reasons common on IIM portals.
How to verify the latest official CAT rules
- Go to the official CAT website for the current season and download the information bulletin / notification PDF (IIMs publish technical upload rules there).
- Find the photograph and signature sections — copy pixel dimensions, aspect constraints, background colour, and JPEG KB caps exactly as printed.
- Skim the portal’s FAQs / help after registration opens; photograph tolerances are sometimes clarified there.
Disclaimer
ImageTool is not affiliated with IIMs or the CAT convening process. This page does not replicate live CAT validation logic — it only helps you resize and compress files locally. Final compliance is yours against the official bulletin and the registration portal for your year.
Cut rejections before you upload
- Resize to the bulletin’s exact pixel box before compressing — fixing KB first often forces awkward crops later.
- Keep critical facial detail inside the “safe” frame if the portal shows a crop preview on mobile and desktop.
- If the form rejects size, step the compressor down by small increments and re-upload — avoid aggressive single-step crushing that adds JPEG artefacts.
Recommended specification
| Field | Guidance |
|---|---|
| Official source | iimcat.ac.in information bulletin |
| Dimensions | Portrait pixel ranges vary — match PDF exactly |
| KB limit | Adjust compressor target to sit clearly below max |
| Appearance | Formal attire / neutral background per bulletin |
How to use
- Note CAT’s exact pixel height × width and JPEG cap.
- Resize using presets as starting points — tweak custom width/height if bulletin differs.
- Compress iteratively until portal validator passes.
Best practices
- Shoot slightly larger then downscale — sharper than scaling tiny photos up.
- Maintain neutral expressions if bulletin forbids smiling.
Common mistakes
- Ignoring signature specs — CAT often requires separate uploads.
- Using filtered selfies — may fail automated checks.
Privacy and quality
Browser-only workflows reduce exposure of biometric-style photographs.
Frequently Asked Questions
What are CAT photograph dimensions and file size limits?
IIM CAT publishes detailed technical requirements each season — pixel ranges and JPEG KB caps change. Use this page’s tools after reading the official PDF on iimcat.ac.in.
Can I reuse my SSC or bank exam photo?
Only if dimensions, background, and file size satisfy CAT’s current rules and the photograph is recent per instructions.
Is my image uploaded?
No — conversion happens entirely in your browser.
Is CAT registration photo resize free here?
Yes — ImageTool runs locally without signup.
HEIC photos from iPhone?
Convert with HEIC to JPG before resizing if needed.
Can I tweak dimensions manually?
Yes — ResizeTool allows editing width/height fields when the bulletin differs from presets.
