Frequently asked questions

When you need a file under 30 KB

Upload forms, email limits and page-speed budgets often come with a hard size cap. This page is preset to 30 KB: drop in a photo and the compressor searches for the highest quality that fits, shrinking dimensions only if quality alone is not enough. The result is the best-looking image that still passes the limit.

How big can a 30 KB image be?

File size depends on content as much as pixels. A plain background compresses far better than leaves or gravel. As a rough guide for a 4:3 photo at 30 KB:

These figures are estimates. The tool always reports the exact size of every file it produces.

Tips for hitting 30 KB cleanly

Crop to the subject first, so pixels are spent where they matter. Avoid re-compressing a file that has already been compressed, because artefacts stack. If a portal also lists a pixel range, set the maximum width to match it before compressing. Aim slightly below the limit, since some systems count 1 KB as 1000 bytes and others as 1024.
