JPEG Image Compression

Compress JPEG images with a visual quality slider for precise control over output size and appearance.

Big image files are usually the main thing slowing down a website, clogging up an email attachment, or eating your phone storage for no good reason. This compression tool lets you decide exactly how much quality you're willing to trade for a smaller file. Upload a JPEG, drag the quality slider from 1 (maximum squeeze — things might get ugly) to 100 (practically untouched), and watch the file size change in real time. You get a side-by-side comparison of original versus compressed so you can see exactly what you're sacrificing. The tool uses the browser's native Canvas API under the hood, but really — just slide until it looks good enough and the size is where you want it. Great for web devs trying to shave off kilobytes, photographers sending previews, or anyone who just needs a smaller file without installing yet another app. And as always, everything stays in your browser.
