The .env line is the one that matters. Everything else here costs disk space; that one costs a credential rotation.

Save it as .gitignore in your project. The file is built in your browser, so nothing about your project is sent anywhere. Browsers rename files that start with a dot — this will arrive as gitignore.txt or similar, so rename it after downloading. Copying the text is usually quicker.

Ignores the right things, starting with the .env that would cost you a credential rotation. A committed secret stays in the git history after the file is deleted, so the only real fix is rotating the credential — which is why the ignore file matters before the first commit rather than after.

What Does Create a .gitignore File Do?

Why Use Web Development Tools in the Browser?

Small web jobs like minifying CSS, checking HTML, escaping a string or writing a Dockerfile rarely deserve a new install. These tools do each one in a tab, and your code is never sent to a server.

“The fastest tool is the one already open in a tab.”

Code checked for errors
Messy code made readable
Number bases converted
Selectors and paths tested

Minified files for faster pages
Config files from templates
CI workflows drafted quickly
Source code stays private

Popular Uses for Developer Utilities

These are the small tasks that interrupt a day of web work.

Minifying assets Shrink CSS or JSON before deploying, then beautify it again to read.
Validating markup Catch unclosed tags and syntax errors in HTML, CSS or JavaScript before publishing.
Docker setups Draft a Dockerfile, Docker Compose file or .dockerignore for a new project.
CI pipelines Generate a GitHub Actions or GitLab CI workflow and adjust it to fit.
Number conversions Convert between binary, decimal, hex and octal while reading low-level data.
Selector testing Try a CSS selector or JSONPath expression against sample input and see matches.
Data URIs Turn a small image into a data URI to embed directly in CSS.
Project files Create .gitignore, EditorConfig and CODEOWNERS files without copying them from old repos.

Frequently Asked Questions

Answers to common questions about this tool.

Do I need to install anything to create a .gitignore file?

No. Create a .gitignore File runs entirely in your browser — there is nothing to download, no extension and no desktop program. It works the same on Windows, macOS, Linux, Android and iPhone.

Is it safe to create a .gitignore file online?

Safer than the usual alternative, yes. Most online tools upload your file to a server you know nothing about, where it sits until someone deletes it. Here the file never leaves your device — the processing happens in the page itself, so there is no server copy to leak, retain or sell.

Is my code sent to a server when I use Create a .gitignore File?

No. Your code is processed in the browser tab, so private repositories, keys in config files and client work stay on your machine. It also means the tool works on locked-down work laptops where installing software is not allowed.

Will minifying break my code?

Minifying removes spaces, comments and line breaks without changing what the code does. Keep an unminified copy for editing, and test the minified version before deploying it.

Are the generated config files ready to use?

They give you a sound starting point based on common settings. Every project is different, so read through the file and adjust paths, versions and secrets before committing it.

Is Create a .gitignore File free with no account?

Yes. There is no login, API key or usage cap. Open the page whenever you need it, even on a machine that is not your own.

Does Create a .gitignore File follow current web standards?

The validators and generators follow current web standards and common tool conventions. Standards keep moving, so for edge cases check MDN or the official specification listed in further reading.
