Smaller image files, without the upload
Most images carry far more data than a web page or email actually needs. Compression trades detail you can't easily see for a much smaller file — a photo that started at several megabytes often drops below a few hundred kilobytes with no obvious loss. This tool does that work entirely in your browser: the picture is read, re-encoded at the quality you choose, and handed back as a download. Because it never leaves your device, it's safe to use on screenshots, documents, or personal photos.
How to use it
- Drop in a JPG, PNG, or WebP image.
- Adjust the quality slider and watch the estimated file size change in real time.
- Compare the preview against the original until the size and sharpness feel right.
- Download the compressed version.
Getting a good result
- Photographs tolerate heavier compression than text or line art, where edges can smear.
- If a PNG stays large, the image may suit JPG or WebP better — those formats handle photos more efficiently.
- Resize oversized images first: a 4000px-wide photo displayed at 800px wastes most of its data.
Questions people ask
Will quality visibly drop? At moderate settings, rarely. Push the slider too far and you'll see blocky areas or soft edges — the live preview is there so you can stop before that point.
Are my images uploaded? No. Everything happens locally in your browser, so private images stay private.
Can I compress several at once? Process them one at a time; each stays on your device and downloads immediately.
