Frequently asked questions
How do I compress an image to exactly 30 KB?
Drop it in β the 30 KB target is already set β and the tool binary-searches the highest quality that still fits, then hands you the file. No slider guesswork.
Is my image uploaded to a server?
No. Compression runs entirely in your browser; the image never leaves your device.
Which formats can I use?
JPG, PNG and WebP input. Output is JPG (works everywhere) or WebP (smaller).
Where the 30 KB limit shows up
The 30 KB target usually comes from small photo and signature fields on registration forms and low-limit avatar uploads. Set it above and download a file that lands just under the cap.
What to expect at 30 KB
30 KB is enough for a tightly-cropped headshot to stay recognisable, though fine detail softens. Signatures and simple graphics look crisp.
A quick tip
Start from the original photo, not a screenshot, and crop before compressing to spend every kilobyte on pixels you keep. For other targets, use the image compressor hub.
