Confused between JPEG, PNG, WebP, and AVIF? We've broken down the technical specifications, performance metrics, and use cases to help you choose the perfect format for your project.
Choosing the right image format can reduce file size by 50–80% while maintaining visual quality—directly improving page load speed, SEO rankings, and user experience. JPEG remains the universal fallback for photographs, but WebP and AVIF offer significantly better compression for modern browsers. PNG is essential for graphics requiring transparency, while SVG excels for logos and icons at any resolution.
Our image compressor supports all major formats and can convert between them. Use the comparison below to decide which format fits your use case, then apply that knowledge when optimizing images for web, social media, or print.

A quick simplified guide for common web scenarios.
Use WebP for modern web performance. Fall back to JPEG only if you need 100% compatibility with older email clients.
Always use SVG for logos when possible. For complex icons with shadows, use PNG to maintain transparency.
Use AVIF for the highest quality product images at the lowest byte size. It ensures your store loads fast even on mobile.
