SVG Optimizer cleans and compresses SVG files by removing editor metadata, redundant attributes, unused definitions, comments, and unnecessary whitespace — reducing file size by 20–60% without any visible change to the graphic. Smaller SVGs load faster, are easier to read, and perform better when used inline in HTML. The optimisation runs entirely in your browser using SVGO logic.
How it Works
1Upload your SVG file or paste the SVG markup directly into the editor.
2The optimiser runs a series of passes: removing editor metadata, merging path segments, collapsing redundant groups, and minifying attribute values.
3The optimised SVG is shown alongside the original with size reduction percentage.
4Download the optimised SVG or copy the markup to embed inline.
Frequently Asked Questions
Will optimisation change how my SVG looks?
No visible change should occur. The optimiser removes only attributes and elements that have no effect on rendering — editor IDs, Inkscape/Illustrator metadata, empty groups, redundant transforms, and default attribute values. The visual output is pixel-identical.
Why are SVGs from design tools so large?
Design tools like Figma, Adobe Illustrator, and Sketch embed metadata about layers, editor state, grid settings, and application version into the SVG. They also use verbose representations for paths and transforms. None of this metadata is needed for display, but it can triple the file size.
What is the typical size reduction?
SVGs exported from Figma or Illustrator commonly shrink by 30–60% after optimisation. Simple icons and logos often achieve the highest reduction ratios. Complex SVGs with many unique paths see smaller but still meaningful savings.
Should I optimise SVGs used as inline HTML or as <img> src?
Both. Inline SVGs benefit from smaller DOM size and faster parsing. SVGs referenced as <img> src benefit from reduced download size. For inline SVGs, you can also remove the xml declaration and doctype, which this optimiser does automatically.
