Frequently Asked Questions
Does WebP support transparency like PNG?
Yes. WebP fully supports alpha transparency, making it a great replacement for PNG on the web with significantly smaller file sizes.
Is WebP supported by all browsers?
WebP is supported by all modern browsers including Chrome, Firefox, Safari, and Edge. Only very old browser versions lack support.
How much smaller are WebP files compared to PNG?
WebP lossless files are typically 26% smaller than PNG. With lossy compression, savings can reach 60-80% while maintaining good visual quality.
Can I choose between lossless and lossy WebP?
Use the quality slider to control compression. Setting quality to 100% gives near-lossless results, while lower values apply lossy compression for smaller files.
Will my transparent backgrounds be preserved?
Yes. Transparency is fully preserved when converting PNG to WebP.
How It Works
This converter uses your browser's built-in Canvas API to process files locally. Your PNG files are decoded and re-encoded as WebP entirely on your device. Nothing is uploaded to any server.
