Drop YAML (YML) files onto the box above, or click it to choose them. ToAny reads the file's contents to detect the type, so a wrong extension does not matter.
Press Convert. There is nothing else to set. The work happens in this tab.
Save the TOML, or download everything as one ZIP if you converted several files.
The YAML to TOML converter is part of this page and runs inside your browser. Your config files are never sent to ToAny or to anyone else.
Nothing has to travel to a server and back, so the conversion starts the moment you press Convert, even on a slow connection.
No sign-up, no email address and no watermark. Add several files and download them together as a ZIP.
YAML's indentation rules are easy to break, and many APIs only accept JSON. TOML is unambiguous and pleasant to edit by hand. YAML is at home in configuration files written by people; TOML is the usual choice for simple configuration files.
Keys, nesting and values carry over. Comments in the YAML file are not carried over, because only the data is read. A YAML file with several documents (separated by ---) is read as a list of documents. TOML needs named keys at the top level and cannot store empty (null) values, so a file with a top-level list or a null is refused, with the offending key named.
YAML expresses the same structures as JSON using indentation instead of brackets, and allows comments. It is the usual choice for configuration in tools like Docker Compose, Kubernetes and GitHub Actions.

No. The YAML to TOML conversion runs inside your browser, on your own phone or computer. The file is not sent to ToAny or to anyone else.
The values are kept. Anything TOML has no way to express, such as formatting, formulas or nesting, is simplified or left out.
Yes. Add as many as you like, convert them together and download each result or all of them as one ZIP.
The steps are the same everywhere because ToAny runs in the web browser: open this page in a current version of Chrome, Edge, Safari or Firefox, add the YAML file, press Convert and save the TOML. There is nothing to install.
Yes. Data files up to 300 MB are accepted; a larger file is refused with a message. Beyond that the limit is your device's memory, since nothing is uploaded; a computer copes with large files better than a phone.
