SVG Minifier

Clean up comments and unnecessary whitespace in an SVG string.

Category: Image Tools

When to use?

Use it to reduce human-made whitespace and comments before putting inline SVG into code.

How to use

  • Paste SVG code.
  • Check the minified result and size change.
  • Copy the result if needed.

Input Explanation

Enter the original SVG code to optimize in the text area.

Calculation Basis

It safely removes unnecessary line breaks, multiple spaces, and HTML comments (<!-- -->) via regex and string processing to optimize file size.

Usage Examples

  • Tidy inline SVG - Reduce unnecessary whitespace to make code-ready SVG.
  • Prepare images for upload - Preview the result, then tidy images for blogs, shops, or social media.
  • Compare results - Check original and result side by side for quality and size.

Examples

  • A 5KB SVG with many comments and indentation → compressed to 3KB
  • Remove comments/whitespace from editor-exported SVG to cut code size

Cautions

  • It processes via browser canvas, so original metadata (EXIF) may be lost or transparent areas may change color.
  • Extremely high-resolution large files may fail to convert due to browser image-decoding limits.

FAQ

Does it do advanced optimization?

It focuses on basic string cleanup. Advanced optimization like path merging needs a specialized tool.

Is the SVG code sent to a server?

No. Whitespace/comment cleanup runs in the browser and is not sent out.

How much smaller does it get?

The more comments and indentation, the bigger the savings — often tens of percent.

Does minifying change the look?

It removes only comments and unnecessary whitespace, so the drawn shape stays the same.
