optimizt is a command-line image optimization tool. It helps you prepare images during frontend development.
JPEG, PNG, WebP, and AVIF processing is performed using the sharp library. SVG processing is performed using the svgo utility.
This is free and open source software.
Features include:
- Compress PNG, JPEG, GIF and SVG lossy and lossless and create AVIF and WebP versions for raster images.
- By default the software performs lossy optimizations.
- Option to perform lossless optimizations:
- When creating AVIF and WebP versions, optimizations are applied that do not affect the visual quality of the images.
- PNG, JPEG, and GIF optimization uses settings that maximize the visual quality of the image at the expense of the final file size.
- When processing SVG files, the settings for Lossy and Lossless modes are identical.
- Force the creation of AVIF and WebP formats.
- Write output to a specified directory.
