Drop in JPG, PNG or WebP images and this tool shrinks them right in your browser, using your own device. Because nothing is uploaded, it is private, works with large files, and has no daily limit or watermark.
For photos, JPEG or WebP at 70–80% quality usually cuts file size dramatically with little visible change. Resizing very large images (for example 4000 px wide down to 1920 px) saves the most. PNG files stay lossless, so the biggest savings come from resizing or converting to WebP.
No. Compression runs entirely in your browser on your device, so your files never leave it.
75% is a good default for photos. Go lower for smaller files or higher if you can see artifacts. Text-heavy screenshots may look better as WebP or PNG.
Already-optimized images can grow when re-encoded. The tool flags this so you can keep the original.
