CSS to LESS Converter

What Is a CSS to LESS Converter?

A CSS to LESS Converter is an online tool that converts standard CSS into LESS format. It helps developers upgrade existing stylesheets by enabling features like variables and nesting, making the code cleaner, more organized, and easier to maintain—without rewriting CSS from scratch.

Example: CSS vs. LESS

Here is a simple look at how the converter tidies up your code. Notice how the LESS version uses nesting to group related styles together, making it much easier to read.

Input (Standard CSS) In standard CSS, you often have to repeat the parent class name (.navbar) for every child element.

CSS

.navbar {
  background-color: #333;
  padding: 15px;
}

.navbar .logo {
  font-size: 20px;
  font-weight: bold;
}

.navbar .nav-link {
  color: white;
  text-decoration: none;
}

.navbar .nav-link:hover {
  color: #ffcc00;
}

Output (Converted to LESS) The converter groups everything inside .navbar. We can also replace the colors with variables (like @primary-bg) so you only have to change the color in one place if you redesign later.

Less

@primary-bg: #333;
@highlight-color: #ffcc00;

.navbar {
  background-color: @primary-bg;
  padding: 15px;

  .logo {
    font-size: 20px;
    font-weight: bold;
  }

  .nav-link {
    color: white;
    text-decoration: none;

    &:hover {
      color: @highlight-color;
    }
  }
}
