Appscodes Simple browser tools for code review and cleanup
Comment remover tool

Remove comments from code

Paste code, choose a language preset, and remove line comments or block comments while keeping quoted strings intact. The tool is designed for quick cleanup before sharing examples, preparing documentation, or reviewing source code.

Appscodes supports a C-like preset for C, C++, C#, Java, JavaScript, PHP, and Swift, plus presets for Python, HTML, CSS, SQL, MATLAB, and Ruby. The code cleanup runs in your browser, so the pasted code is not uploaded for comment removal processing.

Assumptions Correct syntax and strings are inside single or double quotes. At most one redundant escape symbol is expected.

When to use a comment remover

A comment remover is useful when you want to publish a compact code sample, compare source code without explanatory notes, or prepare snippets for documentation. It can also help when pasted examples contain many temporary notes, debugging comments, or old TODO lines that make the code harder to read.

The Appscodes comment remover lets you choose the symbols that represent line comments, escape characters, and block comments. This makes it flexible enough for many languages and custom formats. The built in presets are shortcuts for common languages, but you can still adjust the symbols manually for special cases.

Automated comment removal should always be reviewed before production use. Some programming languages have complex syntax rules, template strings, raw strings, nested blocks, or documentation formats that may need a manual check after cleanup.
