Your SVG is Probably 3x Larger Than It Needs to Be

When you export an SVG from Figma, Adobe Illustrator, or Inkscape, the file comes packed with editor metadata, XML declarations, empty groups, comments, and formatting whitespace that has nothing to do with how the image looks. A simple icon that should be 2KB ends up as 8KB.

SVG Optimizer strips all of that out using SVGO — the same engine used by Webpack, Vite, and other build tools. What you get is a clean, minimal SVG that looks identical but loads significantly faster.

Two Ways to Optimize

  • Upload SVG Files

    Upload up to 20 SVG files at once. Click any file in the list to see its before/after comparison using the drag slider. Download optimized files individually or all together as a ZIP.

  • Paste SVG Code

    Paste your SVG code directly into the editor. Get the optimized code output instantly with file size stats. A before/after visual slider shows how the SVG looks before and after optimization.

What Gets Removed During Optimization

  • XML comments and editor notes that serve no visual purpose
  • Extra whitespace, indentation, and line breaks between elements
  • Empty group elements with no children
  • Metadata tags added by design tools — title, desc, editor version info
  • Redundant or default attribute values that browsers assume anyway
  • Unnecessary XML declarations and doctype headers
  • Unused style definitions and duplicate CSS rules

Before/After Slider — Verify Nothing Changed

The most important question after optimization is whether the SVG still looks the same. The before/after comparison slider answers this directly — drag it left and right to compare the original and optimized versions side by side. If they look identical, the optimization was safe.

Frequently Asked Questions

Design tools add a lot of metadata, comments, editor-specific attributes, and formatting to SVG files. This extra code is useful during editing but completely unnecessary for web use. SVG optimizer removes all of it, reducing file size by 30-70% without affecting how the SVG looks.

No. The optimizer only removes unnecessary code — comments, whitespace, metadata, empty elements, and redundant attributes. The visual output remains identical. You can verify this using the before/after slider preview.

File upload lets you optimize up to 20 SVG files at once with a visual preview for each. Paste code mode lets you paste SVG code directly and see the optimized code output alongside a before/after visual preview.

No. All optimization happens entirely in your browser using SVGO. Your files never leave your device.

Remove comments deletes <!-- --> blocks. Remove whitespace collapses extra spaces and line breaks. Remove empty elements deletes tags with no content. Optimize attributes cleans up redundant attribute values. Remove metadata deletes title, desc, and editor metadata. Minify path numbers reduces decimal precision in path coordinates. Merge styles inlines and minifies CSS within the SVG.

Typically 30-70% depending on how much extra code the original file contains. SVGs exported from Figma or Adobe Illustrator tend to have the most unnecessary code and benefit the most from optimization.

Yes. In File upload mode you can upload up to 20 SVG files at once. All files are optimized together and you can download them individually or as a single ZIP file.
