How exact-KB compression works
This adjusts JPG/WEBP quality and, if needed, slightly reduces pixel dimensions until the file lands just under your target — typically with a small safety margin so a strict portal doesn't reject it for being a byte over. The compression runs on a background thread when your browser supports it, so the page stays responsive even on a large photo. Your file is never sent to a server — everything happens on your device.
When you need a 30 KB photo
A small step up from 20 KB, occasionally used as a photo limit by stricter state-level forms.
If 20 KB looked too soft for your portal's preview, try this size before jumping straight to 50 KB.
Frequently asked
How do I compress a photo to exactly 30 KB?
Upload the photo above, leave the target at 30 KB, and click Compress. The tool adjusts quality and, if needed, resolution until the file is just under 30 KB, then lets you download it — nothing is uploaded to a server.
Is this tool free and safe to use?
Yes. It's free, requires no account, and runs entirely in your browser using your device's own processing — your image is never sent anywhere.
Which exams use a 30 KB photo limit?
No single major exam uses exactly 30 KB as its only limit, but it's a useful size when a form's stated range falls between the more common tiers — always check your own notification's exact number.
