Code Comment Remover

What Does This Tool Do?

It removes comments matching common patterns for a chosen language style - // and /* */ for JavaScript/PHP/CSS-style languages, # for Python/shell-style languages, and -- for SQL.

Why Use This Tool?

Useful for quickly stripping comments from a code snippet before sharing or minifying it, when a full language-specific tool isn't necessary.

How to Use It

1. Paste your code.
2. Choose the comment style matching your language.
3. Copy the comment-stripped result.

Important Notes

This uses pattern matching, not a full language parser - a comment-marker character appearing inside a string literal (e.g. a URL containing //) can be incorrectly treated as a comment start. Always review the output before using it.

Example

// calculate the order total
function total(items) {
    /* prices are in paise */
    return items.reduce((s, i) => s + i.price, 0); // sum
}

becomes:

function total(items) {

    return items.reduce((s, i) => s + i.price, 0);
}

Lines that held only a comment are left empty, so the code keeps its line structure; remove the blank lines afterwards if you want it compact.

Good Reasons to Strip Comments

• Sharing a snippet publicly without internal notes, ticket numbers or names.
• Pasting code into a question or an AI prompt where comments add noise.
• Comparing two versions of a file when only the code matters.
• Reducing the size of a script for an embed when no build tool is available.

Check These After Removing

• URLs in strings such as "https://example.com" - the // can be mistaken for a comment.
• Licence headers that must legally stay in distributed code.
• Special comments that tools rely on: /*! preserve */, // @ts-ignore, # type: ignore, #!/usr/bin/env python shebang lines.
• CSS hacks or conditional comments in older HTML emails.

To shrink code further, use the Code Minifier; to count what remains, use the Code Line Counter.
