YAML to XML Converter

Convert YAML files to XML free in your browser — no signup, no install, and the file is never uploaded to a server. XML opens almost anywhere, so the result works where YAML did not.

What changes in this conversion

  • XML opens almost everywhere, so the converted file will work on devices and programs that refused the original YAML.
  • The data structure (objects, arrays, values) is preserved exactly — only the notation changes. Comments in the original file are not carried over.

How to use

  1. Add your YAML file

    Drag the YAML file onto the drop area above, or click it to pick a file from your device. You can add several files at once.

  2. Confirm XML as the output

    XML is already selected as the output format on this page. This format converts straight through with no extra settings.

  3. Run the conversion

    Press the convert button. Processing happens on your own device, so the time depends on your computer rather than a server queue.

  4. Download the XML file

    When it finishes, download the XML file. Converting multiple files gives you the option to download them together as a ZIP.

Frequently asked questions

Is converting YAML to XML really free?

Yes. YAML to XML conversion is completely free with no signup, no watermark, and no daily limit on the free plan for ordinary use.

Are my YAML files uploaded to a server?

No. The conversion runs entirely inside your browser using WebAssembly, so the YAML file never leaves your device. That is also why it works without an internet connection once the page has loaded.

Does the XML file get bigger than the YAML?

It can go either way. Both formats are lossless, so nothing is thrown away — the size difference comes from how each one packs the same data.

Is there a file size limit for YAML to XML conversion?

The free plan handles files up to 200MB. Because processing happens on your own device, very large files depend on your computer's memory rather than a server quota.
