SVG Optimizer
Make your SVG smaller right in your browser — strip editor cruft, comments, and metadata without changing how it looks. Free and instant.

How to optimize an SVG
- Open your SVG — drag it onto the tool, choose a file, or paste from your clipboard.
- It's optimized instantly — the tool cleans and minifies the markup for you.
- See the savings — the before and after sizes show how much smaller it got.
- Download — save the optimized .svg, visually identical and lighter.
Why optimize an SVG?
SVGs exported from Illustrator, Figma, or Inkscape carry a lot of extra data — comments, metadata, unused definitions, and long decimal numbers. Optimizing removes all of that without changing how the image looks, often cutting 40 to 70 percent of the file size. Smaller SVGs load faster and are easier to paste inline.

About the formats
An SVG is XML text, and files exported from Illustrator, Figma, Sketch, or Inkscape carry a lot of weight that has nothing to do with the image: editor comments and metadata, generous decimal precision, empty groups, unused definitions, and redundant attributes. Optimizing strips that overhead so the file is smaller and cleaner without changing a single visible pixel.
What this conversion actually does
The optimizer runs SVGO (its in-browser build) with the standard preset in multipass mode: it removes comments, editor metadata, empty groups and defs, and redundant attributes, and rounds long coordinate numbers to a sensible precision. The viewBox is always preserved, so the SVG keeps scaling correctly. Aggressive mode goes further — it tidies element IDs and drops the fixed width and height attributes (leaning on the viewBox) for a fully responsive inline SVG.
When to use it
Run any SVG through the optimizer before you ship it: icons in a UI, an inline logo in your HTML, illustrations on a landing page, or assets in an icon font or sprite. Smaller SVGs load faster, paste more cleanly into code, and are far less noisy to read and diff.
Good to know: The default settings are lossless and safe. Aggressive mode rewrites element IDs and removes width/height — avoid it if external CSS or JavaScript targets those IDs, or if a tool relies on the SVG's fixed pixel size. If a file is already lean there may be little left to remove, and badly malformed markup is returned unchanged rather than broken.

Frequently asked questions
How do I optimize an SVG?
Drop your SVG above and it's cleaned and minified automatically. The before and after sizes show the savings, and you download a visually identical but lighter file. It all runs in your browser.
Is the SVG optimizer free?
Yes — free, no watermark, no sign-up, and no limit on the number of files. The optimized SVG is a normal file you can use anywhere.
Will optimizing change how my SVG looks?
No. The default settings preserve the look exactly — the viewBox is kept so it still scales, and only safe, lossless cleanups are applied. Aggressive mode additionally tidies IDs and drops fixed width/height, which is ideal for inline SVGs.
Where is my SVG processed?
The optimization happens in your browser, so the cleaned SVG is created on your own device. How any data associated with the tool is handled is described in our privacy policy.
