    Why convert YAML to JSON?

    To convert YAML files to JSON, drop them on the counter above.

    Most files convert in seconds: no queue, no email address, and the JSON result saves straight to your computer or phone.

    How to convert YAML to JSON

    1. Add your YAML files

      Drag your YAML files onto the counter or pick them with Choose files. You can add several at once.

    2. Check the settings

      The defaults suit most cases. Change quality, size or other options if you like; after a change, one click converts again.

    3. Conversion starts by itself

      Each file is converted to JSON and its row is stamped CONVERTED.

    4. Download your JSON file

      Get the file with Download. With several files you can download them all as one ZIP.

    Frequently asked questions

    Is converting YAML to JSON free?

    Yes, completely free. No account, no daily limit, no watermark and no queue.

    Does it work on a phone?

    Yes. It works on iPhone, iPad and Android, with no app to install.

    Is there a file size limit?

    There is no size limit set by us. Files of hundreds of MB convert too; very large files take longer and are handled more comfortably on a computer than on a phone.
