Frequently Asked Questions

Yes, completely free with no limits on file size or number of conversions. No account registration required.

No. The entire conversion happens in your browser using JavaScript. Your INI data never leaves your device, making it safe for sensitive configuration files.

Yes, once the page loads, the conversion works offline. The JavaScript libraries are cached in your browser, so you can convert files without an internet connection.

Since the conversion runs in your browser, file size is limited only by your device's available memory. Files up to hundreds of megabytes work well on modern devices.

Standard INI format with sections in square brackets and key=value pairs. Also supports configuration files using semicolon (;) or hash (#) comments.

Yes. INI sections are converted to YAML nested objects, preserving the hierarchical structure. Section names become top-level keys in the YAML output.

Yes. The converter handles Windows-style INI files with CRLF line endings and various encoding formats. Both ASCII and UTF-8 encoded INI files are supported.

Comments are preserved where possible. INI comments (using ; or #) are converted to YAML comments using the # syntax in the appropriate locations.

INI values are strings by default. The converter attempts to detect and convert numeric values, booleans (true/false), and null values to proper YAML data types.

If an INI file contains duplicate keys within the same section, the last value wins, following standard INI parsing behavior. This is preserved in the YAML output.
