Compress an image to 30 KB
30 KB is the pragmatic target when a portal specifies a photo band of 20–50 KB — the range used by SSC applications, among others. It sits far enough from both edges that validation never becomes a coin flip, and at passport-photo dimensions the quality is comfortably good.
As with every preset on this site, compression happens in your browser. The photo of your face stays on your machine.

How it works
- Open this page — the compressor is already set for “Compress image to 30 KB”.
- Drop your image into the box, click to browse, or paste it with Ctrl+V.
- The tool re-encodes the image on your own device until it fits the target — nothing is uploaded.
- Check the preview and file size on the result card, then download.
Quality at 30 KB
Passport-style photos at 400–550 px: clean, form-ready results. The face stays sharp; you may notice slight smoothing in plain backgrounds, which portals don’t care about.
General photos: usable at up to ~700 px on the long side. Beyond that, prefer a larger KB target if your destination allows it.
Getting the dimensions right
For exam-form photos, pairing 30 KB with 3.5 × 4.5 cm dimensions (about 413 × 531 px at 300 DPI) gives a result that passes both the size check and the visual review.
Frequently asked questions
My form says “photo between 20 KB and 50 KB”. What should I do?
Use this 30 KB preset (or the SSC preset which also fixes the pixel dimensions). Mid-band targets survive the small measurement differences between your computer and the portal’s validator.
Will the date and name stamp on my photo survive compression?
Yes — printed text on a photo is high-contrast and compresses well. Make sure the stamp is legible in the original; compression won’t rescue text that’s already blurry.
Does the tool remove EXIF data like location?
Yes, as a side effect: the image is re-drawn onto a canvas and re-encoded, which produces a fresh file without the original camera metadata (GPS position, device model, timestamps).
