Why this tool exists

A focused workflow, without the design-app overhead

SVG exports often contain comments, editor metadata, and formatting that add weight without changing the picture. The optimizer removes safe-to-drop markup and shows the byte savings before you replace the original.

Useful for

  • Reducing icon and logo transfer size
  • Cleaning SVG markup before code review
  • Preparing assets for inline HTML or email templates

How to use it

From input to finished asset

  1. 01

    Paste or upload

    Load one SVG and inspect it in the preview before making any changes.

  2. 02

    Choose cleanup options

    Remove comments, collapse whitespace, and trim redundant XML declarations independently.

  3. 03

    Compare and save

    Review the original and optimized byte counts, then copy or download the smaller SVG.

Conservative cleanup

This optimizer focuses on markup cleanup and avoids rewriting paths or coordinates, so visual changes are less likely.

Savings you can verify

The workspace reports both byte counts and the percentage saved instead of making a vague compression claim.

Preview before replacing

Keep the visual preview beside the output and compare it with the original before using the result in production.

Local processing

Optimization happens in the current tab. Your source artwork does not leave the browser.

Common questions

What does the SVG optimizer do?+

It strips comments, whitespace, and redundant XML attributes while keeping your SVG visually identical — producing a smaller file for web use.

Do I need to upload my file to use SVG Optimizer?+

No. This tool runs in your browser, so your SVG stays in the current tab and is not uploaded to GenSVG.

Can I use the exported SVG in a commercial project?+

The tool does not add a watermark or a new license. Your right to use the result depends on the license and ownership of the source artwork you provide.
