Frequently asked questions
Will transparency be preserved?
Yes! WebP fully supports transparency (alpha channel) just like PNG. Your transparent backgrounds, logos, and graphics will look exactly the same but with a much smaller file size.
How much smaller will files be?
WebP files are typically 50-70% smaller than PNG files while maintaining the same quality and transparency. This makes them ideal for web use.
Is WebP supported in all browsers?
Yes, WebP is now supported in all major browsers including Chrome, Firefox, Safari, and Edge. Browser support is now over 95% globally.
Are my files uploaded anywhere?
No! All conversion happens directly in your browser using JavaScript and WebAssembly. Your images never leave your device - they're never uploaded to any server.
