CAT 2026 Photo Size — IIM Admission Upload
The Common Admission Test (CAT) application portal requires uploaded photos to be 20–100KB in JPEG format at passport-size. IIM applications through CAT require passport-style photos within strict size limits for identity verification. Use PhotoSizeTool to compress your photo to the exact specification — all processing runs in your browser, so your personal photo stays private.
What You Need to Know
CAT is the entrance exam for IIMs and other top management institutes. The application process runs through iimcat.ac.in, which requires recent passport-size photographs. Since your CAT photo is used for verification at multiple IIM interview rounds, investing in a clear, well-compressed photo pays off throughout the admission process.

Pro Tip

Frequently Asked Questions
What are the exact photo requirements for CAT?
The Common Admission Test (CAT) portal typically requires photos in JPEG format, under 20–100KB, at passport-size. Requirements may vary slightly by exam cycle — always verify against the official notification.
Why does the CAT portal reject my photo upload?
Common reasons: file exceeds 20–100KB, wrong format (must be JPEG), incorrect dimensions, or blurry image. Compress to the exact size with our tool and verify with the portal's preview.
Should I use JPG or PNG for CAT forms?
CAT forms typically require JPEG. JPEG is preferred for photos — it produces smaller files. PNG may be accepted but results in larger file sizes.
Can I use this tool for both photo and signature?
Yes. Use this tool for photo compression, and the dedicated Signature Resizer for signature images — they have different size and dimension requirements.
Is my photo stored on your servers?
No. All compression happens in your browser. Your photo is never uploaded to our servers — especially important for exam application photos containing personal identity information.
