WebP is Google's modern image format that offers 25-35% smaller file sizes than JPEG at equivalent visual quality, with support for both lossy and lossless compression plus transparency.

Can I compress WebP further?

Yes. Even existing WebP files often have room for further optimization, especially if they were converted from other formats or generated with non-optimal settings.

Does it support animated WebP?

Animated WebP optimization is supported. Frame data is compressed while maintaining animation timing.

What quality setting is best?

Quality 75-85 provides the best balance for web use. WebP at quality 80 typically looks as good as JPEG at quality 90 but is significantly smaller.

Is WebP supported by all browsers?

All major modern browsers support WebP: Chrome, Firefox, Edge, Safari (iOS 14+, macOS 11+), and Opera. Global browser support is approximately 96%.

Should I use WebP over JPEG?

For web use, WebP is generally better: smaller files, same quality, and transparency support. Use JPEG only when maximum compatibility with very old browsers is required.

Can I compress multiple WebP files?

Yes. Drag and drop multiple files or click to select several at once.
