SVG files exported from Figma, Illustrator, or Inkscape carry a lot of baggage — editor metadata, unnecessary attributes, comments, and verbose formatting that bloat file size without adding any visual detail. A SVG optimizer strips all of that out, often reducing file size by 30–70%. This tool processes everything locally in your browser, so your graphics stay private.

Upload an SVG file or paste the code directly, choose which optimizations to apply, and get a leaner SVG in milliseconds. Need readable SVG code for editing? Switch to Prettify mode.

How to Optimize SVG — Step by Step

1. Upload or paste your SVG. Drag an SVG file into the upload zone, or paste SVG code directly into the text area. The tool accepts files up to 5MB.
2. Select optimizations. Toggle options like removing comments, metadata, editor data, empty attributes, and whitespace. All are checked by default for maximum compression.
3. Click "Optimize SVG." The tool cleans your SVG locally and shows before/after previews with exact file size stats.
4. Copy or download. Grab the optimized SVG code or save a clean .svg file. Both the original and optimized previews render side by side so you can verify nothing broke.

If you also need to convert your SVG to PNG or JPG, check out the Ultimate Image Converter.

Why Use This SVG Optimizer

• Massive size reduction — strip editor bloat for 30–70% smaller SVGs
• Visual preview — compare original and optimized SVGs side by side before committing
• Granular control — choose exactly what gets removed: comments, metadata, editor namespaces, empty attributes
• 100% private — your files stay in your browser, never sent to any server
• File upload + paste — works with SVG files or raw SVG code
• Prettify mode — format minified SVGs into readable code for editing
• No dependencies — no npm, no CLI, no Python, no account

Common Use Cases

Cleaning SVGs exported from Figma

Figma's SVG exports include comments and sometimes unnecessary grouping. Running the output through this optimizer strips that overhead and gives you a production-ready icon or illustration.

Optimizing icon sets for web

A set of 50 SVG icons might total 200KB straight from the design tool. After optimization, that drops to 60–80KB — significant savings when icons load on every page. Pair this with the Image Compressor for your raster images too.

Cleaning Illustrator and Inkscape exports

Adobe Illustrator adds proprietary data-name attributes and Inkscape adds sodipodi: and inkscape: namespaces. Both are useless for web rendering. This optimizer's "Remove editor data" option strips them all in one click.

Preparing SVGs for inline HTML

Inline SVGs render faster than external files because they eliminate an HTTP request. But inline code needs to be compact. Optimize your SVG first, then paste it into your HTML.

Reducing SVG animation file weight

Animated SVGs with SMIL or CSS animations can be especially bloated. Removing metadata and unnecessary attributes keeps the animations intact while cutting size.

How SVG Optimization Works

SVG is XML-based, which means it's both human-readable and verbose. Design tools add extra layers of information that browsers don't need for rendering.

This optimizer removes:

• XML comments — <!-- --> blocks that explain nothing to the browser
• Metadata elements — <metadata> tags with RDF data from design tools
• Editor namespaces — Inkscape (sodipodi:, inkscape:), Illustrator (i:, x:), and Sketch attributes
• Empty attributes — attributes with no value or blank strings
• <desc> and <title> — optional descriptive elements (keep them if you need SVG accessibility)
• Whitespace — extra spaces, indentation, and line breaks between elements
• XML declarations and DOCTYPE — unnecessary for SVGs embedded in HTML5 pages

For deeper optimization (path data simplification, shape-to-path conversion, precision reduction), tools like SVGO on GitHub provide advanced transforms. This browser tool focuses on safe, lossless cleanup that won't alter your graphic in any way.

Tips & Best Practices

Always preview after optimizing

The side-by-side preview is there for a reason. Check that gradients, filters, and clipping paths still render correctly. Complex SVGs with overlapping effects occasionally reference removed elements.

Keep <title> and <desc> for accessibility

If your SVG serves as a meaningful image (not just decoration), keep the <title> and <desc> elements. Screen readers use them. Uncheck that option for accessible SVGs.

Remove editor data for production, keep it for source files

Inkscape and Illustrator namespaces let you re-edit the SVG in those tools. Strip them for production files, but keep the original source with editor data in your project folder.

Use Prettify mode for manual fine-tuning

After optimization, switch to Prettify mode and beautify the output. This makes it easy to spot remaining redundant groups or attributes you want to remove manually.

Combine with CSS for icon systems

Optimized inline SVGs work great with CSS for color changes via fill: currentColor. Optimize your SVGs first, then use the CSS Formatter to keep your stylesheets clean.

Test in multiple browsers

Safari, Chrome, and Firefox have slightly different SVG rendering. A quick check across browsers after optimization catches edge cases, especially with filters and masks.

Frequently Asked Questions

Optimized SVGs mean faster-loading icons, lighter illustrations, and cleaner inline code. This SVG optimizer handles the cleanup in seconds without npm packages, Python scripts, or CLI configurations. Bookmark it for every design export, and use the Image Converter when you need to convert formats too.
