# PicBrewery

> PicBrewery is a free online image optimizer and converter. All image encoding and decoding run in your browser with WebAssembly (MozJPEG, libwebp, libavif, oxipng). Source images are not uploaded to PicBrewery for processing.

The marketing site may load analytics or advertising scripts only after opt-in cookie consent (see Privacy Policy). The converter itself still runs entirely client-side.

- [JPEG](https://picbrewery.com/formats/#jpeg) — baseline photos, no transparency
- [PNG](https://picbrewery.com/formats/#png) — lossless, alpha, larger on photos
- [WebP](https://picbrewery.com/formats/#webp) — photos + UI, alpha, animation, broad support
- [AVIF](https://picbrewery.com/formats/#avif) — best compression, slower encode, newer Safari
