Image Format Converter

Image Format Converter converts between all major image formats including JPEG, PNG, WebP, BMP, TIFF, GIF, and ICO using Pillow server-side processing. WebP delivers superior compression producing files up to 30 percent smaller than JPEG while maintaining comparable visual quality, making it ideal for modern web performance. PNG provides lossless compression with full transparency support. ICO conversion produces browser-ready 256x256 favicon files. Format-specific handling ensures JPEG output always strips transparency correctly by compositing on white background.
