CSS/JS Remove

Tool Guide

Introduction

The online CSS/JS redundant space and blank line cleaner is a lightweight code purifier built specifically for front-end developers and web loading performance optimization. It supports one-click removal of messy consecutive spaces, blank line breaks, trailing whitespace, and specific trailing characters in CSS stylesheets or JavaScript files, and can optionally strip code block comments.

Core Features

1. Precise line normalization: A refined code regex parsing engine cleans up redundant trailing whitespace without breaking the code's original logic, bracket indentation, or string content.
2. High compression ratio: With one click, it merges consecutive blank line breaks, minimizes layout gaps, greatly reduces the network size of source files, and speeds up page loading.
3. Local sandbox execution: All normalization and cleaning algorithms run in a closed loop entirely within the browser memory. Zero uploads and no network connection—absolutely protecting the security of your core JS/CSS algorithms and business logic source code.

How to Use

1. Paste the original JS or CSS code you want to slim down into the large text box above.
2. Based on your optimization goals, toggle specific cleanup switches in the configuration panel (e.g., keep/remove multi-line comments, whether to merge blank lines, etc.).
3. Click the Clean button, and the system will instantly output the normalized, streamlined code on the right or below. Simply click to copy or download the file.
