Is the ini to yaml converter free?

Yes, completely free. No sign-up, no daily limit, no watermark on the output.

Are INI sections preserved?

Yes. Each section becomes a top-level YAML mapping with the section name as the key.

Are data types preserved?

Yes. Numbers and booleans are auto-detected and written without quotes, so they stay as YAML numbers and booleans rather than strings.

How are nested sections handled?

Dotted section names like [server.dev] are converted into nested YAML structures, preserving the hierarchy.

Are INI comments preserved?

No. Comments are dropped during conversion. If you need comments in the YAML, add them with # after conversion.

What is INI to YAML Conversion?

INI to YAML conversion takes a classic INI config file and rewrites it as YAML, the indented format used by Kubernetes, Docker Compose, GitHub Actions, and most modern config tools. INI is flat by design (sections and key=value pairs); YAML uses indentation and supports nesting and types. A ini to yaml converter walks your INI, turns each section into a YAML mapping, and writes the values with their proper types. You'll usually run a ini to yaml conversion when you're modernizing legacy config or moving data into a tool that prefers YAML.

Why Convert INI to YAML?

YAML has quietly become the standard for configuration in modern tooling. Almost every DevOps tool (Kubernetes, Helm, GitLab CI, GitHub Actions, CircleCI, Ansible) reads YAML by default. INI is what legacy PHP, MySQL, Git, and many desktop apps produced over the years. Converting ini to yaml online is the fastest way across without retyping. Use a ini to yaml tool when you need to migrate php.ini or my.cnf settings into Kubernetes manifests or Helm values, modernize legacy config into a format DevOps teams can edit, generate YAML examples for docs from INI samples, or clean up older config files that are hard to maintain in INI.

How Our INI to YAML Converter Works

When you click Convert, the tool parses your INI, takes each [section] header, and turns it into a YAML mapping. Key=value pairs inside become indented entries under that mapping. Numbers and booleans are auto-detected so they don't get quoted as strings. Dotted section names like [server.dev] become nested YAML structures. The output uses two-space indentation (the YAML standard) so it loads cleanly in any YAML parser. Everything runs in your browser. Your INI data never leaves your device.

Features You Get

One-click conversion: hit Convert and the YAML appears in the output panel.
Section mapping: each [section] becomes a top-level YAML key with indented entries.
Type detection: numbers and booleans are auto-detected and written without quotes.
Nested sections: dotted names like [server.dev] become nested YAML mappings.
Upload support: load a .ini or .cfg file from your device or drag-and-drop it into the input.
One-click copy: grab the YAML output with the Copy button and paste it into your config file.

How to Use the Tool

Paste your INI content into the input editor, or use the Upload File button to load a .ini or .cfg file.
Click the Convert button to generate the YAML output on the right.
Skim the result. YAML being indented makes structure mistakes obvious fast.
Click the Copy button to copy the YAML to your clipboard.

Common Use Cases

Config modernization: moving php.ini or my.cnf settings into YAML configs the team can edit.
Kubernetes migration: turning INI settings into YAML manifests or Helm values.
DevOps pipelines: preparing legacy config for GitHub Actions or GitLab CI workflows.
Documentation: generating readable YAML examples from INI samples.

Example Conversion

Input (INI)

[server]
host=localhost
port=3000
debug=true

Output (YAML)

server:
  host: localhost
  port: 3000
  debug: true
