JPEG, PNG, WebP — converted instantly with WASM
Industry-leading lossy compression via MozJPEG WASM. Best for photos — dramatically smaller than browser-native JPEG encoding.
Lossless OxiPNG encoding preserves full transparency and every pixel. Ideal for graphics, logos, and UI assets.
Google's libwebp WASM encoder produces files 25–35% smaller than JPEG with full transparency support. The modern choice for web.
