Optimize Your SVG
About SVG Optimizer
SVG files exported from design tools like Figma, Illustrator, Inkscape, and Sketch contain substantial unnecessary data: editor metadata, XML comments, empty groups, hidden elements, and redundant attributes. This bloat increases file size with zero visual benefit.
Our SVG optimizer runs entirely in your browser — no upload, no server, no signup. Your SVGs never leave your device. Use the customizable optimization options to control exactly what gets cleaned.
Why AI Cannot Reliably Optimize SVGs
AI language models struggle with SVG optimization for several reasons:
- Visual hallucination: AI may remove attributes it thinks are "unnecessary" but that are actually critical for rendering (viewBox, transforms, clip paths)
- Syntax corruption: AI often produces malformed SVG markup with unclosed tags or invalid path data
- Inconsistent results: The same SVG run through AI twice produces different output — unacceptable for production assets
- No size feedback: AI cannot show you real byte savings or compare before/after visually
Our tool uses deterministic DOM parsing and targeted regex — same input always produces the same output. Every optimization is safe and reversible.
How It Works
- Input: Paste SVG code or upload an SVG file
- Configure: Toggle optimization options (comments, metadata, editor data, empty groups, default attributes, whitespace, dimensions)
- Optimize: Click "Optimize SVG" — processing happens instantly in your browser
- Review: See before/after preview, file size comparison, and savings percentage
- Export: Copy the optimized code or download as .svg file
Optimization Options Explained
- Remove comments
- Strips all XML comments (<!-- ... -->) from the SVG. Safe for production use.
- Remove metadata
- Removes <metadata>, <title>, and <desc> elements. Safe unless your SVG relies on accessible titles.
- Remove editor data
- Strips Inkscape, Illustrator, and Sodipodi namespaces and attributes (sodipodi:, inkscape:, etc.). Safe for web use.
- Remove empty groups
- Deletes <g> elements that contain no children. Safe — no visual impact.
- Remove default attrs
- Removes attributes set to their default values (e.g., fill-opacity="1", stroke="none"). Safe.
- Minify whitespace
- Collapses unnecessary whitespace and indentation. Safe — comparable to HTML minification.
- Remove width/height
- Strips width and height attributes while keeping viewBox, making the SVG responsive. Use with caution — affects layout.
Typical Size Savings
| SVG Source | Before | After | Savings |
|---|---|---|---|
| Simple icon (hand-coded) | 1.2 KB | 0.8 KB | 33% |
| Figma export (complex) | 24.5 KB | 8.2 KB | 67% |
| Illustrator export (detailed) | 56.3 KB | 18.7 KB | 67% |
Frequently Asked Questions
Is my SVG data private?
Yes. All processing happens in your browser using JavaScript. Your SVG code never leaves your device. No upload to any server, no data storage, no tracking.
Will optimization break my SVG?
The "safe" options (comments, metadata, whitespace) never affect rendering. Options like "remove empty groups" and "remove default attrs" are also very safe. "Remove width/height" can change layout behavior — preview before downloading.
How much can I reduce file size?
Typical savings range from 20-70% depending on the SVG source. Design-tool exports (Figma, Illustrator) benefit most. Hand-coded SVGs see smaller gains.
Can I optimize multiple SVGs?
Currently one at a time. For bulk optimization, consider using SVGO CLI (Node.js) which can process entire directories.
Does this tool use SVGO?
No. Our optimizer uses pure browser-based DOM parsing and targeted string operations. This means no dependencies, no upload, and instant processing. For most optimization tasks the results are comparable to SVGO.
What file formats are supported?
Input: SVG files or raw SVG code. Output: Optimized SVG code or downloadable .svg file.
