YAML Minifier
Minify and compress YAML by removing whitespace

What is YAML Minifier?
Need to shrink your YAML file size? YAML Minifier removes all unnecessary whitespace and line breaks from your YAML (YAML Ain't Markup Language) files. Perfect for production environments where smaller file sizes mean faster transfers and lower bandwidth usage.
According to YAML specification, minified YAML is functionally identical to formatted YAML but takes up less space. Our minifier preserves all your data and structure while removing everything unnecessary. Great for config files, data files, or any YAML that needs to be compact.
Everything happens in your browser – your YAML never leaves your computer. Minify, download, and use your compact YAML right away.
What Makes This Tool Different
Whitespace Removal
Removes all unnecessary spaces, tabs, and line breaks. Your YAML becomes compact while staying perfectly valid.
Structure Preservation
All your YAML structure stays intact. Keys, values, nested objects, and arrays remain exactly the same – just without the formatting.
Size Reduction Stats
See exactly how much space you saved. We show you the original size, minified size, and percentage saved so you know the impact.
File Upload Support
Got a big file? Just upload it. Works great for minifying those massive YAML configs or data files without copy-pasting.
Download Minified YAML
One click to download your minified YAML file. Perfect for production deployments where smaller files mean better performance.
Syntax Validation
We validate your YAML before minifying. Invalid YAML gets caught early, so you know the minified version will work correctly.
How It Works
Paste or Upload YAML
Paste your YAML code into the left editor, or click "Upload" to load a file. You can also click "Sample" to see an example. The tool accepts any valid YAML structure.
Automatic Minification
As soon as you paste, the minifier processes your YAML and displays the compact version on the right. All whitespace is removed, making it much smaller while staying valid. You'll see the size reduction stats.
Download or Copy
Click "Download" to save the minified YAML file, or "Copy" to copy it to your clipboard. The minified YAML is ready to use in production or wherever you need compact YAML.
When You'd Actually Use This
Production Deployment
Minify YAML config files before deploying to production. Smaller files mean faster loading times and reduced bandwidth usage.
API Optimization
Minify YAML responses to reduce payload size. Faster API calls and lower bandwidth costs, especially important for mobile apps or high-traffic APIs.
Storage Efficiency
Save storage space by minifying YAML files. Great for archiving large amounts of YAML data or when storage costs matter.
Network Transfer
Reduce transfer times by sending minified YAML. Smaller files transfer faster, especially over slow connections or when dealing with large datasets.
Common Questions
Is my YAML data stored?
Nope. Everything happens right in your browser. Your YAML never leaves your computer – we don't even see it.
Does minification break my YAML?
No. Minified YAML is functionally identical to formatted YAML. All keys, values, and structure stay exactly the same – we just remove whitespace.
How much smaller does it get?
It depends on how much whitespace your YAML has. Typically, you'll see 20-50% size reduction, sometimes more for heavily formatted YAML with lots of indentation.
Can I format it back?
Yep. Use our YAML Formatter to make minified YAML readable again. Minification is reversible – formatting just adds whitespace back.
What about multi-line strings?
Multi-line strings are preserved exactly as they are. We only remove whitespace between keys and values, not content inside strings.
Does it work with large files?
Yep. Since everything happens in your browser, it depends on your device. Small files minify instantly. Very large files (10MB+) might take a few seconds, but they'll still work.
Other YAML Tools You Might Need
Minification is just one YAML task. Here are other tools that work well together:
