Which Codec Should You Choose?

📷 For Photos

Use MozJPEG (JPG) for photographs and realistic images. It offers the best balance of quality and file size for complex images.

🎨 For Graphics

Use OxiPNG (PNG) for screenshots, logos, and graphics with sharp edges or text. It preserves every detail perfectly.

🌐 For Modern Web

Use WebP for websites. It supports both lossy and lossless compression and often produces smaller files than JPG and PNG.

Local Processing

All compression happens right in your browser. We never upload your images to any server.
