About SVG Optimization
- • Upload up to 5 SVG files at once
- • Each file is optimized individually with progress tracking
- • Remove unnecessary code, comments, and metadata
- • Configurable settings let you control which elements to optimize
- • Perfect visual quality is maintained after optimization
- • Optimized SVGs load faster and use less bandwidth
- • Use individual download buttons or download all files as a ZIP
- • All processing happens in your browser - files never leave your device
About SVG Optimizer
The SVG optimizer reduces SVG file sizes by removing unnecessary code, comments, metadata, and whitespace using the powerful SVGO library. This tool optimizes SVG files for faster web loading, reduced bandwidth usage, and improved website performance while maintaining perfect visual quality.
Why use a SVG Optimizer?
Optimizing SVG files reduces loading times, improves website performance, and decreases bandwidth costs while maintaining crisp vector quality. Smaller SVG files enhance user experience, improve SEO rankings, and reduce storage requirements without any visual quality loss. Clean SVG code is also easier to maintain and manipulate.
Who is it for?
This tool is perfect for web developers optimizing site performance, graphic designers preparing SVG assets for web use, UI/UX designers cleaning up exported SVGs from design tools, and content creators needing smaller SVG files without compromising quality or editability.
How to use the tool
Upload your SVG files using the file picker or drag-and-drop (up to 5 files at once)
Use Add More Files to select additional SVGs, or Clear All to remove every file and start over
Toggle the seven optimization settings that appear once files are selected: Remove comments, Remove hidden elements, Remove empty attributes, Minify styles, Remove viewBox (may affect scaling), Convert colors to hex, and Remove scripts and event handlers
Click Optimize to run SVGO in your browser — each file's status updates from Ready to Optimizing to Completed
Check the original size, optimized size, and percentage saved shown for each completed file, plus the overall optimization summary
Download the optimized SVGs individually, or click Download All to get every completed file at once as a ZIP
Use Remove on a completed file to discard it from the list if you don't need its result
Frequently Asked Questions
How do I optimize an SVG online?
Upload up to 5 .svg files using the file picker or drag-and-drop. The tool runs SVGO (SVG Optimizer) — the industry-standard library — to remove unused metadata, redundant whitespace, default attribute values, and hidden elements, with optional toggles for stripping styles, the viewBox, and inline scripts/event handlers. Click Optimize to process the files, then download each one individually or as a ZIP. Optimisation runs entirely in your browser — your SVG never leaves the device. Typical reduction: 30-80% for SVGs exported from design tools.
Will optimization change how my SVG looks?
No — visual rendering is preserved exactly with the default settings. SVGO removes only metadata, hidden elements, and redundant code; the visible paths, fills, strokes, and effects render identically. The one setting that can affect appearance is 'Remove viewBox', which is off by default because it can break responsive scaling — leave it off unless you understand the tradeoff. Each file's before/after size is shown once optimization finishes, so you can confirm the result before downloading.
Is my SVG uploaded to a server?
No. Optimisation runs entirely in your browser via the SVGO library executing as plain JavaScript — no WASM, no network call. Your SVG never reaches a server, never gets logged. Verify in DevTools' Network tab: optimisation produces zero HTTP requests. Safe for proprietary brand SVGs, internal product graphics, or sensitive technical diagrams. The browser is the right place for SVG optimisation since the operation is pure text manipulation.
How much can I reduce SVG file size?
Typical reductions: 30-50% for SVGs exported from Illustrator or Figma (lots of metadata, default attributes, unnecessary precision). 50-80% for SVGs with embedded editor data or excessive precision. <20% for already-optimised SVGs (already minified or hand-coded). Biggest wins come from removing inkscape:/sodipodi:/adobe-specific namespace attributes, reducing decimal precision in path data, and stripping comments and empty attributes — all handled automatically by SVGO's default preset.
What does SVG optimization actually remove?
SVGO's default preset automatically strips editor-specific metadata (inkscape:, sodipodi:, adobe:), XML declarations and DOCTYPE, unused namespace declarations, redundant default attribute values, and excess path-data precision. On top of that, this tool exposes seven optimizations as checkboxes so you can turn each on or off: removeComments, removeHiddenElements, removeEmptyAttributes, minifyStyles, removeViewBox, convertColorsToHex, and removeScripts. Everything else in the default preset runs automatically and isn't individually configurable here.
Can I configure which optimizations to apply?
Yes — seven checkboxes let you control specific SVGO behaviour: removeComments, removeHiddenElements, removeEmptyAttributes, minifyStyles (minify `<style>` blocks and style attributes, and drop unused CSS rules), removeViewBox (off by default — removing it can break scaling), convertColorsToHex, and removeScripts (strips `<script>` elements and inline event handlers like `onclick`). Everything else SVGO's default preset does — path-data optimisation, collapsing groups, removing default attribute values, and so on — runs automatically.
How is SVG Optimizer different from SVG to Data URI?
Optimizer reduces SVG file size while keeping it as a separate .svg file. [SVG to Data URI](/tools/svg-to-data-uri/) converts an SVG to a base64 or URL-encoded data URI for embedding directly in CSS or HTML (eliminates one HTTP request, useful for tiny icons). The two tools are complementary: optimize first to reduce size, then convert to data URI if you want to embed inline. For larger SVGs used multiple times on a page, separate file + browser caching beats embedding.
When should I optimize SVGs?
Whenever an SVG goes from a design tool (Illustrator, Figma, Inkscape) to production. Design tools embed significant editor metadata and use generous precision that doesn't matter for rendering. Optimisation typically saves 30-80% of file size with no visual difference — a clear win for Core Web Vitals (LCP, FCP). For SVG icon libraries (hundreds of icons), batch optimization via SVGO's command-line tool is more efficient: `svgo -f input-dir -o output-dir`.
