Statement

I've created and maintain several open-source projects. Some of them, like pngquant and MozJPEG, power many 3rd party tools and services that save huge amounts of bandwidth worldwide.

  • pngquant and libimagequant

    The best possible widely-compatible compression of images with an alpha channel.

  • ImageOptim app & ImageAlpha

    GUIs making image optimization easy and convenient

  • Sblam!

    A free web service for filtering out spam in web forms (blocking HTTP spambots) transparently to the users and accessible to screen readers.

  • lossy animgif + gifski encoder

    Halving bandwidth of the Internet cat traffic.

  • Sparkle

    Auto-updater for non-Appstore (and thus DRM-free) Mac apps.

I'm also maintaining several libraries and tools for the Rust programming language.
