Compress image to 30 KB

Thirty kilobytes sits between the two most common form limits. Several state public service commissions and scholarship portals use it. At this size a head-and-shoulders photo around 400 px tall still looks clean, and a signature keeps every stroke.

At 30 KB you can expect around 400 to 550 px for a photo. The exact number depends on how much fine detail the image has: skies and plain walls compress well, foliage and fabric don't.

1. Drop or paste the image. Nothing is uploaded; the work happens in your browser, even offline.
2. The tool encodes the image as JPEG at several quality levels and keeps the one that lands just under 30 KB.
3. If even the lowest acceptable quality is too big, it reduces the pixels a little and tries again, so the result is the largest image that fits.
4. Download the file, or share it straight into WhatsApp or the form on a phone.

Every result shows the final size and pixel dimensions before you download. Need a fixed pixel size too? Set Resize to Exact size (crop) and type the width and height.

This limit is common for state PSC portals with a 30 KB cap, scholarship forms and ID cards. If the portal also lists a minimum size (for example "20 KB to 50 KB"), open More options and fill in Min (KB): the tool pads the JPEG so it is never rejected for being too small, without touching the pixels.
