WebP is a modern image format developed by Google, significantly reducing file size compared to traditional formats, with better compression than JPEG and PNG. This tool uses the browser's native WebP encoder to complete the conversion directly on your device, both fast and secure. Supports lossy and lossless storage modes, transparency, and animation.
• Lossy compression (recommended): Suitable for photos, significantly reduces file size
• Lossless storage mode: Suitable for graphics requiring precise colors
• Quality slider: 0-100, recommended 80-85
• Auto mode: Lets the browser choose the optimal solution
Tip: Local processing allows you to try different settings repeatedly without worrying about data consumption.
Conversion feature support:
• Chrome 23+: Full support
• Firefox 65+: Full support
• Edge 18+: Full support
• Safari 16+: macOS 11+ support
Note: Even if a browser supports viewing WebP, it may not support encoding. This tool will automatically detect and notify.
Advantages of converting animated GIF to animated WebP:
• Significant reduction in file size
• Support for more colors (16.7 million vs 256 colors)
• Better compression algorithm
• Support for semi-transparency effects
Limitation: Some browsers may only convert the first frame; it is recommended to use Chrome/Edge for best support.
1. Privacy protection: Photos do not leave your device
2. Fast speed: No need to wait for upload/download
3. No limits: Not restricted by server quotas
4. Instant preview: See conversion effects in real time
5. Batch processing: Convert multiple files simultaneously
The only limitation is your device's processing power and memory.
Q: How to use converted WebP in web pages?
A: Use the '<picture>' tag to provide a fallback solution, ensuring compatibility.
Q: Why are some PNGs larger after converting to WebP?
A: Simple graphics may be better with PNG; WebP is suitable for complex images.
Q: Batch conversion quantity limit?
A: Depends on device memory; it is recommended to process 5-10 images per batch on mobile devices.
Q: How to verify local processing?
A: The tool still works normally when offline, proving pure local processing.
