Image Format Comparison

PNG provides lossless compression with transparency support, ideal for logos and graphics with sharp edges. JPEG uses lossy compression that excels at photographs and complex images with gradients, but has no transparency. WebP offers smaller file sizes than both PNG and JPEG while supporting transparency, and AVIF compresses even further at the cost of slower encoding and slightly narrower browser support.

When to Convert

Converting between formats helps optimize images for specific use cases. Convert PNG to JPEG to reduce file size when transparency is not needed, and pick a background color to fill transparent areas. Convert JPEG to PNG when you need lossless quality for editing. Use WebP or AVIF for web delivery to improve page load times. The quality slider lets you fine-tune the compression level for lossy formats.
