Frequently Asked Questions

What is WebP?

WebP is a modern image format developed by Google that provides superior compression for images on the web. It supports both lossy and lossless compression, plus transparency.

Is WebP supported by all browsers?

WebP is supported by all major modern browsers including Chrome, Firefox, Safari, and Edge. Only very old browser versions lack support.

Why compress WebP if it's already optimized?

WebP files can still be further optimized by reducing quality or dimensions, especially if the original was saved at maximum quality or has large dimensions.

How does WebP compression compare to JPG?

WebP typically produces files 25-35% smaller than equivalent quality JPG. Compressing an already-optimized WebP can still yield meaningful savings.

Does Compresso upload my WebP files?

No. Compresso processes everything in your browser using client-side JavaScript. Your images never leave your device — complete privacy guaranteed.

Can I batch compress WebP images?

Yes! Upload multiple WebP files at once, compress them all with consistent settings, and download individually or as a ZIP file.
