A CLI tool that compresses PNG, JPEG, GIF, and SVG images and creates AVIF/WebP versions for web optimization.
Optimizt is a command-line image optimization tool that helps frontend developers prepare images for the web. It compresses PNG, JPEG, GIF, and SVG files either losslessly or lossily, and can create AVIF and WebP versions from raster images. The tool solves the problem of needing multiple applications for different image optimization tasks by providing a unified solution.
Frontend developers and web developers who need to optimize images for web performance, reduce file sizes, and generate modern image formats like AVIF and WebP.
Developers choose Optimizt because it consolidates multiple image optimization workflows into a single CLI tool, supports both lossy and lossless compression, integrates with popular IDEs, and offers Docker support for easy deployment. Its flexibility and comprehensive format support make it a versatile choice for web image preparation.

Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Supports compression and conversion for PNG, JPEG, GIF, SVG, AVIF, and WebP, covering all major web image formats as highlighted in the README's multi-format features.
Offers both lossy and lossless modes, allowing developers to balance file size and quality, with default lossy for best balance and lossless for maximum quality.
Seamlessly integrates with JetBrains IDEs, VS Code, and Sublime Text, and provides Docker support for easy deployment in CI/CD pipelines, as documented in the integrations section.
Can optimize single images or entire directories recursively, saving time on bulk operations with command-line flags for output customization.
Relies on tools like Guetzli for lossless JPEG optimization, which can cause installation errors such as 'spawn guetzli ENOENT' if npm scripts are disabled, as noted in the troubleshooting section.
Focuses only on compression and format conversion; lacks built-in features for resizing, cropping, or advanced edits, which might require additional tools in some workflows.
Requires custom configuration files (.optimiztrc.cjs) for advanced settings, and the recursive search for configs can be cumbersome for simple or one-off use cases.
