How ZXZX Compression Works

ZXZX uses advanced compression algorithms that analyze each image and selectively reduce data in areas where the human eye won't notice the difference. Unlike simple resize or quality reduction, our approach preserves important details while removing redundant information.

The compression happens entirely in your browser using the Canvas API and WebAssembly. Your images are never uploaded to any server, making ZXZX one of the most private image compression tools available.

Frequently Asked Questions

Is image compression really free?

Yes, ZXZX is completely free with no hidden costs. There are no file size limits, no watermarks, and no registration required. You can compress unlimited images.

Will compression reduce image quality?

At medium settings (80%), compression is virtually invisible to the human eye. Even at aggressive settings (40%), most images retain acceptable quality for web use. You can compare before and after using our preview tool.

What's the difference between JPG, PNG, and WebP compression?

JPG is best for photographs. PNG is best for graphics with transparency. WebP offers the best compression for both types. Converting to WebP typically saves 25-35% compared to JPG.

Are my images uploaded to your server?

No. All compression happens in your browser using JavaScript. Your files never leave your device. This is why ZXZX is one of the safest image tools available.

Can I compress images on my phone?

Yes. ZXZX works on all modern mobile browsers including Chrome and Safari on iOS and Android. The interface is fully responsive.
