Where a 30 KB limit is used

A 30 KB limit is most often used for photographs on many online application forms. A 30 KB photo cap is widely used by many online application and admission portals. It is a comfortable middle ground — small enough to upload quickly, large enough to keep a face recognisable.

Tip for hitting 30 KB cleanly

A front-facing photo with even lighting and a plain background compresses cleanly to 30 KB. Avoid patterned backgrounds, which add detail and push the file size up.

⚠️ File-size rules vary between forms and change between exam cycles — always confirm the exact limit in the official notification before you upload.

Frequently asked questions

What dimensions suit a 30 KB photo?
Around 3.5×4.5 cm (roughly 200×230 px) works well. At that resolution a 30 KB JPG stays clear enough for form verification.
How do I compress an image to 30 KB?
Upload your photo above — the target is already set to 30 KB. Click Compress and the tool lowers the quality just enough to bring the file at or under 30 KB, then lets you download it. Nothing is uploaded to a server.
Will the image still be clear at 30 KB?
The tool keeps the highest quality possible while meeting the 30 KB limit. For photographs on many online application forms, 30 KB is enough to stay clear; very small targets naturally soften the image more.
Is it free and private?
Yes — completely free, no signup, no watermark, and the compression runs entirely in your browser so your file never leaves your device.
