WebP is a modern image format developed by Google, reducing file size by 25-35% compared to JPEG and 26% compared to PNG. This tool uses the browser's native WebP encoder, completing the conversion directly on your device, both fast and secure. Supports lossy and lossless compression, transparency, and animation.
• Lossy compression (recommended): Ideal for photos, significantly reduces file size
• Lossless compression: Ideal for graphics requiring precise colors
• Quality slider: 0-100, recommend 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 usage.
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:
• File size reduced by 50-70%
• Supports more colors (16.7 million vs 256)
• Better compression algorithm
• Supports semi-transparency
Limitation: Some browsers may only convert the first frame, recommend using 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 fallback options for compatibility.
Q: Why are some PNGs larger after converting to WebP?
A: Simple graphics may be better in PNG, WebP is ideal for complex images.
Q: Batch conversion quantity limit?
A: Depends on device memory, recommend 5-10 per batch on mobile devices.
Q: How to verify local processing?
A: The tool still works offline, proving it's purely local processing.
