Supports JPEG, PNG, WebP — up to 50MB
This tool compresses your images entirely in your browser using the HTML5 Canvas API. Your images are never uploaded to any server — they stay 100% private on your device. Simply drag and drop your images, adjust the quality slider, and download the compressed versions. Supports batch compression of multiple files at once.
If you’re not sure where to start, try these common setups:
Tip: if an image is huge (e.g. 4000px wide) and you only need 1200px, use the Image Resizer first — resizing usually saves more than compression alone. See: Image compression basics.
Do you upload my images?
No. This compressor runs locally in your browser and does not upload files to our servers.
Why did my PNG not shrink?
PNG is already optimized for lossless graphics and may not compress well. For photos, JPEG/WebP typically shrink much more.
Why does quality look worse?
Very low quality settings can introduce blockiness and banding. Increase the slider until artifacts are no longer visible.
