How it works

Four steps.

  1. 01

    Paste your YAML code directly into the input area or upload a YAML file (.yaml, .yml) using the upload button.

  2. 02

    Choose between Minify or Format mode using the toggle buttons. Click Settings to customize options like indentation size, line width, and comment removal.

  3. 03

    View the processed YAML in real-time. Check the statistics panel (when minifying) to see file size reduction and compression percentage. Use side-by-side or tabbed view modes for comparison.

  4. 04

    Copy the processed YAML to your clipboard with one click, or download it as a new YAML file. The tool automatically generates optimized or formatted YAML.

FAQ

Questions.

What is YAML minification and formatting?

YAML minification removes unnecessary whitespace and formatting to reduce file size, while formatting adds proper indentation and structure for readability. Both are important because: Minification reduces file size for faster configuration loading Formatting improves code readability and maintainability Both help optimize YAML-based applications and CI/CD pipelines Reduces bandwidth usage and storage costs

Will minification break my YAML?

No, our YAML minifier preserves all YAML structure and functionality while removing only unnecessary whitespace. The minified YAML will behave exactly the same as your original YAML, just with a smaller file size. However, we recommend testing the minified YAML in your development environment before deploying to production.

What's the difference between minify and format modes?

The tool offers two modes: Minify: Removes whitespace, comments, and unnecessary formatting to reduce file size Format: Adds proper indentation, line breaks, and structure to improve readability You can switch between modes at any time to suit your needs.

Can I customize the formatting indentation?

Yes! In Format mode, you can adjust the indentation size (1-8 spaces) and line width (0-200 characters) in the Settings panel. This allows you to customize the formatting to match your project's coding style preferences.

Does the tool validate YAML?

The tool parses YAML and will show errors if the YAML syntax is invalid. This helps ensure your YAML is properly structured before processing.

What file size reduction can I expect?

File size reduction varies depending on your YAML. Typically, you can expect 30-60% reduction with standard minification. The actual reduction depends on factors like the amount of whitespace, comments, and formatting in your original YAML.

Can I process YAML with anchors and aliases?

Yes! The tool handles YAML with anchors (&), aliases (*), and complex nested structures. Both minification and formatting preserve all YAML features.

Is the processed YAML production-ready?

Yes, the processed YAML is production-ready and can be used directly in your applications. However, we always recommend keeping a backup of your original YAML file and testing the processed version thoroughly before deploying to ensure everything works as expected.
