Shrink a JPG, PNG, WebP or HEIC image to 30 KB or less without uploading it. Quality is lowered only as much as needed, and the dimensions are reduced only if quality alone can’t reach the target.
Step by step
- Add images: Drop one image or a whole batch.
- Check the target: The target is pre-set to 30 KB; adjust it if needed.
- Compress: Download each result, or all of them as a ZIP — the final size is shown for each.
Good to know
Exam portals often also set a minimum size — use the minimum-KB option if yours does.
Questions
Are my files uploaded?
No. Everything runs in your browser on your own device — nothing is sent to a server. Once a page has loaded it keeps working offline, except that text recognition downloads its language data the first time you use it.
