About JavaFormatter
Free online Java code formatter. Paste messy Java code, get clean, properly indented output instantly.
What We Do
JavaFormatter takes unformatted or inconsistently styled Java source code and reformats it with proper indentation, consistent brace placement, and clean whitespace. Whether you inherited a codebase with mixed tabs and spaces, pasted code from a forum, or just want to standardize your team's code style, this tool handles it in seconds.
Why JavaFormatter
IDE formatters are great, but they require you to open a full project. Sometimes you just have a snippet from Stack Overflow, a code review comment, or a quick script that needs cleanup. JavaFormatter is the fastest way to format Java code without launching an IDE, configuring a project, or installing anything.
How It Works
- Paste your Java code into the editor and click Format. The formatted result appears instantly.
- All formatting happens server-side using a proper Java parser — not regex hacks. This means correct handling of nested blocks, string literals, and comments.
- No sign-up, no login, no limits. Format as much code as you want.
- Your code is processed transiently and not stored. We do not keep copies of formatted code.
What Gets Formatted
Indentation (4-space default), brace placement, line wrapping for long statements, whitespace around operators, blank lines between methods, and import ordering. The formatter follows standard Java conventions similar to Eclipse and IntelliJ IDEA default profiles.
