optimizt

Optimizt is a command‑line utility that processes raster and vector images for web deployment. It can compress PNG, JPEG, GIF, and SVG files using either lossy or lossless algorithms, and it can generate AVIF and WebP versions of raster images. The tool relies on the sharp library for most formats, svgo for SVG optimization, gifsicle for GIF handling, and Guetzli for lossless JPEG compression.

The program is aimed at frontend developers who need a single solution for reducing image payloads and creating modern‑browser formats. It offers a range of flags to control output, such as forcing re‑creation of AVIF/WebP files, selecting lossless mode, specifying output directories, and adding filename prefixes or suffixes. Configuration can be customized via a .optimiztrc.cjs file or a user‑provided config.

Optimizt is distributed as an npm package and also as a Docker image, allowing use in local development environments or containerised pipelines. It integrates with JetBrains IDEs and Visual Studio Code, and it can be invoked directly from the shell or incorporated into build scripts.
