Mazanoke: The Privacy-First Image Optimizer

Image optimization has become essential to our digital workflows. Yet most popular platforms—TinyPNG, Compressor.io, iLoveIMG—trade your privacy for convenience, send your photos to unknown servers, and charge recurring fees for features that should be standard. Mazanoke is here to change that. This open-source, browser-based image optimizer puts you back in control, offering a beautifully simple, lightning-fast, and privacy-first way to optimize your images—on your terms.
