SVG Optimizer
Clean and minify SVG code to shrink file size and speed up your website — right in the browser.
Fewer decimals means smaller files with barely any visible difference.
Everything runs in your browser. Your files are never uploaded.
SVG files exported from design tools are almost always two to five times larger than they need to be, because the exporter packs in editor metadata, redundant precision, comments, and invisible cruft that the browser does not need to render the image. An SVG is just XML — text describing shapes — so all of that overhead ships to every visitor and slows the page down for no visual benefit. This optimizer strips the waste while preserving the exact rendered result: it removes the metadata, trims excessive decimal places, and cleans the markup, typically cutting file size substantially, all in your browser.
How the optimizer works
Paste your SVG code or upload the file, and the optimizer parses it and removes what does not affect rendering: editor comments and metadata, empty groups, redundant attributes, and needlessly long decimal coordinates. The visible image stays pixel-identical while the file shrinks. You can see the before-and-after size and the cleaned code side by side. Everything runs locally — your SVG is never uploaded, which matters for proprietary logos and icons.
What gets removed
Editor metadata <metadata>, editor: namespaces
Comments <!-- Generator: ... -->
Excess precision d="M12.00000001" → "M12"
Empty elements <g></g>, unused defs
Redundant attrs default values, dead styles
Whitespace indentation, line breaks
Rendered pixels: unchanged. File size: much smaller.The single biggest win is usually coordinate precision. Design tools export path data with absurd decimal precision — a point at 12.000000001 pixels — but a screen renders in whole pixels, so nothing past two or three decimal places is ever visible. Rounding that precision alone can cut a complex icon's file size by a third with zero visual change. The metadata removal is the other easy win: an Illustrator or Figma export can be half comment and namespace declarations that no browser reads.
What to know about SVG optimization
- 1SVGs are text, so they compress and cache like text. This is their superpower over raster formats: an optimized SVG gzips further on the server, scales to any size without quality loss, and stays crisp on every screen density. For logos, icons, and simple illustrations, a well-optimized SVG usually beats even a WebP.
- 2Inline critical SVGs directly into your HTML to save a request. A small icon pasted as inline SVG loads with the page and can be styled and animated with CSS, with no separate file fetch. For icons used once, inlining the optimized code is often faster than linking an external file, and this tool gives you the clean code to inline.
- 3Optimization is safe because it never touches the rendered output. Unlike lossy image compression, SVG optimization only removes data the browser ignores — metadata, precision no screen can show, dead markup. The image is mathematically identical after optimization, so there is no quality tradeoff to weigh; it is pure waste removal.
- 4Watch out for over-optimization breaking animations or scripts. Aggressive tools can remove IDs and attributes that your CSS or JavaScript relies on to target elements. If an SVG is animated or interactive, optimize conservatively and test, because the ID an optimizer strips as 'unused' might be the hook your animation depends on.
- 5Simplify the artwork before optimizing the code. The biggest SVG savings often come from the design, not the export: fewer nodes, merged paths, and removed hidden layers shrink the file at the source. An optimizer cleans the export, but a path with a thousand unnecessary points is best fixed in the design tool before it ever reaches the code.
Frequently asked questions
Will optimizing an SVG change how it looks?
No. SVG optimization only removes data that does not affect rendering — editor metadata, comments, dead markup, and decimal precision finer than any screen can display. The visible image is mathematically identical before and after, which is what makes SVG optimization fundamentally different from lossy image compression: there is no quality tradeoff. The one caveat is animated or scripted SVGs, where aggressive optimization can remove IDs your code needs, so those should be optimized carefully and tested.
Why is my exported SVG so large?
Because design tools include a lot the browser never needs: editor metadata and namespace declarations, generator comments, empty groups from your layer structure, and path coordinates with far more decimal precision than any screen can render. A logo exported from Illustrator or Figma can easily be half overhead. Optimization strips all of it, commonly cutting the file size substantially with no change to the visible result.
Is SVG better than PNG for logos and icons?
Usually, yes. An SVG is resolution-independent, so it stays perfectly crisp at any size and on any screen density without needing multiple versions, and an optimized SVG is often smaller than an equivalent PNG for simple graphics. It can also be styled and animated with CSS. PNG wins only for complex, photographic-style imagery that SVG cannot describe efficiently; for flat logos, icons, and illustrations, optimized SVG is typically the better choice.
Is my SVG code uploaded anywhere?
No. The optimization runs entirely in your browser, so your SVG is processed locally and never transmitted, logged, or stored. You can confirm this by disconnecting from the internet; the tool keeps working. This matters for proprietary logos, brand assets, and any icon you would not want leaving your machine before it is published.
Can I still edit an SVG after optimizing it?
Yes, but it may be less convenient. Optimization removes editor-specific metadata and layer structure, so reopening an optimized SVG in a design tool works but you lose the named layers and groups that made editing organized. The best practice is to keep your original, editable master file and optimize only the copy you deploy — that way you get clean output for the web and a workable source for future edits.
