SVG Optimizer
Strip editor metadata, comments, and unused markup from SVG code to shrink the file.
TL;DR: SVG Optimizer is a free, browser-based tool that lets you strip editor metadata, comments, and unused markup from SVG code to shrink the file.
About this tool
Strip the editor metadata, comments, and unused markup that design tools like Adobe Illustrator and Inkscape routinely embed in exported SVG files, without changing how the SVG renders. These exports often include an entire hidden layer of cruft — XML comments naming the exact software version, empty title and description tags, editor-specific namespaced elements and attributes used only by that editor's own interface — none of which affects the visible graphic at all.
Key Features
- Removes XML comments
- Removes empty metadata, title, and description elements
- Removes Inkscape and Adobe editor-specific namespaced elements and attributes
- Collapses unnecessary whitespace between tags
- Validates the input is genuine SVG before processing
- Runs entirely in your browser — your SVG is never uploaded
How to Use
- Paste your SVG code, or upload an .svg file.
- Click Optimize.
- Copy or download the cleaned SVG code.
When to use it
- Shrinking icon files exported from Illustrator or Inkscape before shipping them in a website or app
- Cleaning up SVG code copied from a design tool before pasting it into HTML or a component
- Removing identifying metadata (software name and version) from an SVG before distributing it
- Understanding exactly what extra markup a specific design tool adds to its exports
- Quick sanity-checking that a piece of SVG code is actually valid before using it
Tips & limitations
- This changes the file's markup, not its visible appearance — comments, metadata, and editor-only attributes don't affect rendering, so the cleaned SVG should look identical to the original
- Editor-specific attributes like inkscape:connector-curvature or sodipodi:role only mean something inside that specific editor's UI — browsers and other tools ignore them entirely, which is exactly why removing them is safe
- This doesn't touch path data precision or geometry — a more aggressive minifier that also rounds coordinate precision can shrink complex paths further, at a small risk of visibly altering fine detail
- If your SVG fails to process, the error message will say so directly — it validates the input is well-formed XML with a real
What actually gets removed
| What | Why it’s safe to remove |
|---|---|
| XML comments | Purely informational (e.g. “Generator: Adobe Illustrator 24.0.0”) — invisible to any renderer |
<metadata> blocks | Editor bookkeeping data, not part of the visible graphic |
Empty <title>/<desc> | An empty accessibility tag adds bytes without adding any actual accessibility value |
| Editor namespaces (inkscape:*, sodipodi:*) | Only meaningful inside that specific editor’s own UI — ignored by every browser and by other tools |
Frequently Asked Questions
- No — everything removed (comments, metadata, editor-specific attributes, extra whitespace) has no effect on rendering. The visible graphic is identical before and after.
- No — this tool doesn't touch coordinate values or path geometry at all, only structural bloat like comments and editor metadata. A more aggressive minifier that also rounds path precision can shrink complex icons further, at a small risk of visible change to fine detail.
- It doesn't usually — but if a file has passed through multiple design tools over its life, it can accumulate leftover namespaced attributes from each one, none of which the current tool actually uses or needs.
- Yes — hand-written or programmatically generated SVGs are processed the same way; if there's no editor cruft to remove, the output will be very close to the input, just with any comments and extra whitespace stripped.
