Frequently Asked Questions

What is WebP format?

WebP is a modern image format developed by Google that provides superior compression compared to JPEG and PNG. It supports both lossy and lossless compression, plus transparency like PNG.

Why should I compress WebP images?

Even though WebP is already efficient, further compression can reduce file sizes by 20-50%. This is especially useful for websites where every kilobyte affects page load speed and SEO ranking.

Is WebP supported by all browsers?

WebP is supported by all major modern browsers including Chrome, Firefox, Safari, Edge, and Opera. It has over 97% global browser support as of 2026.

Can I compress WebP files while maintaining transparency?

Yes. Our compressor handles WebP transparency (alpha channel) just like PNG. Your transparent WebP images will remain transparent after compression.

Are my WebP images uploaded to a server?

No. All WebP compression happens locally in your browser. Your images never leave your device, and they are cleared from memory when you close the tab.
