Is the env to toml converter free?

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

Are values automatically typed?

Yes. Numbers and booleans are detected and converted to proper TOML types; strings get TOML's standard double quotes.

Are comments preserved?

No. Lines starting with # are ignored during conversion. If you want comments in the TOML, add them after conversion.

Does the converter handle quoted values?

Yes. Single and double-quoted .env values are correctly unwrapped, so the TOML contains the actual string with proper TOML quoting.

Is the output valid TOML?

Yes. The output follows the TOML 1.0 spec and loads cleanly in standard parsers like @iarna/toml or tomli.

Is it safe to convert .env files with secrets?

Yes. The conversion runs entirely in your browser, so your .env data (including any secrets) never leaves your device.

What is ENV to TOML Conversion?

ENV to TOML conversion takes a .env file and rewrites it in TOML, a modern config format with proper types and stricter syntax. .env is dead simple (KEY=VALUE per line); TOML adds explicit types (strings get quoted, numbers and booleans don't), supports arrays and dates, and is the format of choice for Rust's Cargo and Python's modern tooling. A env to toml converter walks your dotenv file and writes the keys with proper TOML syntax, including the right quoting for each value.

Why Convert ENV to TOML?

TOML is what people pick when they want config that's easy to read, hard to break, and supports proper types. It's used by Cargo, Poetry, Hatch, Hugo, Zola, and a long list of Go and Rust projects. .env files are great for local development but limited when you need structured, typed config. Converting env to toml online is the fastest way to move dotenv values into a modern toolchain. Use this tool when you need to migrate .env settings into a Rust or Python project config, modernize app configuration into a strongly-typed format, share environment values in a format that's friendlier to diff in git, or move toward a config that's harder to mistype.

How Our ENV to TOML Converter Works

When you click Convert, the tool parses your .env file line by line, splits each on the first equals sign, and writes the key-value pairs with proper TOML syntax. Strings get wrapped in double quotes, numbers stay unquoted, and booleans (true/false) are detected automatically. Quoted .env values (single or double quotes) are unwrapped first so the inner string lands in TOML correctly. Lines starting with # are ignored. Everything runs in your browser. Your .env data never leaves your device.

Features You Get

One-click conversion: hit Convert and the TOML appears in the output panel.
Type detection: numbers and booleans stay unquoted; strings get proper TOML double quotes.
Quote handling: single and double-quoted .env values are correctly unwrapped before output.
Comment skipping: lines starting with # are ignored, matching dotenv loader behavior.
Upload support: load a .env file from your device or drag-and-drop it into the input.
One-click copy: grab the TOML output with the Copy button and paste it into your config file.

How to Use the Tool

Paste your .env content into the input editor, or use the Upload File button to load a .env file.
Click the Convert button to generate the TOML output on the right.
Verify the quoting and types look right for your tool.
Click the Copy button to copy the TOML to your clipboard.

Common Use Cases

Rust and Python projects: moving local .env values into Cargo.toml or pyproject.toml configs.
Config modernization: turning dotenv variables into a strongly-typed TOML format.
Static site generators: migrating local .env to Hugo or Zola TOML config.
Stricter configs: moving from untyped .env to TOML for fewer config-related bugs.

Example Conversion

Input (ENV)

SERVER_HOST=localhost
SERVER_PORT=3000
DEBUG=true

Output (TOML)

SERVER_HOST = "localhost"
SERVER_PORT = 3000
DEBUG = true
