Common Admission Test — resize your photo and documents to the exact size required. Nothing is ever uploaded.
CAT's exact photo/signature specs haven't been loaded into this tool yet. You can still resize your photo using the general tool below — just enter the dimensions and file-size range from the official notification.
Also need to: compress a PDF to a size limit or make a passport-style photo?
Common Admission Test applicants need their photo to match the portal's exact upload requirements — exact numbers for which haven't been loaded into this tool yet (see the notice above). National-level entrance tests process lakhs of applications through fully automated portals, so a photo or signature that's a few KB over the limit, or slightly the wrong pixel size, is rejected instantly rather than flagged for manual review.
This page still gives you the full resizer tool below — you'll just need to enter CAT's dimensions and file-size limits yourself from the official notification, since they haven't been confirmed here yet.
National-level entrance tests process lakhs of applications through fully automated portals, so a photo or signature that's a few KB over the limit, or slightly the wrong pixel size, is rejected instantly rather than flagged for manual review. Entering the target pixel size and KB range once, instead of fighting with an image editor's percentage-based "save for web" slider, is what actually gets a file to land inside a specific window on the first try.
The resizer binary-searches JPEG quality first (the gentlest way to shrink a file) and only reduces the actual pixel dimensions if quality alone can't fit under the maximum — so a photo doesn't get visibly softer than it needs to be just to hit a byte count.
Check the final pixel dimensions, not just the file size — a correctly-sized-in-KB image at the wrong width/height can still be rejected. Everything runs in your browser using Canvas and WebAssembly — your photo is never uploaded anywhere, including to this site.
Common reasons a CAT photo or signature gets rejected:
This tool doesn't have CAT's exact photo size loaded yet — check the official notification (linked above) and enter the dimensions into the general resizer below.
No. Cropping, background removal, and compression all run locally in your browser — your photo is never sent to a server, including ours.
The background isn't plain — a patterned wall, furniture, or another person visible behind you. This tool's crop-and-compress flow is built specifically to avoid that.
A phone photo works fine as long as the lighting is even and the background is plain — this tool's crop and background removal handle the rest.
Always check the official CAT notification directly at https://iimcat.ac.in before submitting — specs in this tool are a starting point, not a guarantee they match the current cycle.
