SVG Optimizer

Paste SVG markup and optimize it with SVGO to strip comments, editor metadata, and redundant data. See the byte savings before and after, the percentage reduction, the minified SVG code, and a live preview, all in your browser.

SVG Optimizer is a free tool that cleans and minifies SVG markup right in your browser using SVGO, the industry-standard SVG optimizer. Paste your SVG and it strips out comments, editor metadata, unused definitions, and other bloat that design tools leave behind, then collapses the result to the smallest safe size. You instantly see the byte count before and after, the percentage you saved, the optimized code ready to copy, and a live preview so you can confirm the artwork still looks right. Nothing is uploaded, so your SVG never leaves your machine.

What is an SVG optimizer?

An SVG optimizer rewrites an SVG file to be as small as possible without changing how it looks. Editors like Illustrator, Figma, Inkscape, and Sketch export SVGs with lots of extra data: XML comments, editor-specific namespaces and metadata, hidden or empty groups, overly precise numbers, and redundant attributes. This tool runs your markup through SVGO, which removes that overhead and rounds and collapses the path and attribute data, so the file downloads faster and inlines more cheaply into HTML or CSS while rendering identically.

How to optimize an SVG

Cleaning up your SVG takes only a few steps:

  1. Paste your raw SVG markup into the input box.
  2. Leave multipass on for the best reduction, or turn on prettify if you want readable output.
  3. Click Optimize SVG to run SVGO in your browser.
  4. Check the before and after byte sizes and the percentage saved.
  5. Confirm the live preview still looks correct, then copy the optimized SVG.

What does the optimizer remove?

SVGO applies a set of safe transformations: it deletes XML comments, the XML declaration and doctype, editor metadata and the metadata element, editor namespaces such as the ones Inkscape and Sketch add, empty groups and unused definitions, and default or redundant attributes. It also collapses whitespace, shortens numbers, and merges paths where it can. The result is markup that is much smaller but draws exactly the same image, which is why the live preview matches your original.

Is optimizing SVG safe and private?

Yes. The optimization runs entirely in your browser with JavaScript, so the SVG markup you paste is never uploaded to a server. The live preview is rendered by pointing an image element at a data URI of the optimized SVG, which displays the artwork without executing any script inside it, and the optimized code is shown as plain text. Nothing you paste is stored or transmitted.

Why use this SVG optimizer?

  • 100% free with no ads, sign-up, or limits.
  • Powered by SVGO, the same optimizer used across the web.
  • Shows the exact byte savings before and after plus the percentage reduction.
  • Strips comments, editor metadata, and redundant data while keeping the image identical.
  • Live preview renders the optimized SVG so you can confirm it still looks right.
  • Runs entirely in your browser, so your markup never leaves your device.

Frequently asked questions

Is the SVG optimizer free?

Yes. Every tool on ToolsSoup is completely free, with no account, sign-up, or hidden limits.

Will optimizing change how my SVG looks?

No. SVGO only applies safe transformations that shrink the file without altering the rendered image, which is why the live preview matches your original. You can compare them side by side before copying.

How much smaller will my SVG get?

It depends on how much extra data your editor added. Files exported from design tools often shrink by a large margin because of the comments and metadata they include. The tool reports the exact byte savings and percentage for your specific SVG.

Is my SVG uploaded anywhere?

No. The optimization and preview run entirely in your browser, so the SVG markup you paste is never sent to or stored on any server.
