About This Tool
Paste or upload SVG code to remove comments, metadata, empty attributes, editor-specific data (Inkscape, Adobe Illustrator, Figma), and unnecessary whitespace. See a before-and-after file size comparison, preview the optimized SVG to confirm visual fidelity, and download the cleaned result in one click.
SVGs exported from design tools often contain large amounts of invisible data that serve no purpose in production. Editor metadata, namespace declarations for tools that authored the file, embedded thumbnails, unused definition blocks, default attribute values, redundant group nesting, and formatting whitespace can bloat an SVG to many times its necessary size. A simple icon exported from Figma might be 4 KB when it could be just 1 KB — a 75% overhead that serves no visual or functional purpose.
This overhead matters because SVG files are typically embedded inline in HTML or served as external resources that block rendering. Every unnecessary kilobyte in an SVG file adds to page weight, increases parse time, and delays the browser's first meaningful paint. For websites with dozens of SVG icons, the cumulative waste can be significant — easily adding tens or hundreds of kilobytes of dead weight to every page load.
The SVG Optimizer applies a comprehensive set of cleanup operations using the browser's built-in DOMParser API. It removes XML processing instructions and comments, strips metadata elements (title, desc, metadata tags), deletes editor-specific namespaces and attributes (Inkscape, Illustrator, Sketch, Figma, Sodipodi), eliminates empty container elements and groups that have no visible children, removes unused definitions from the defs block, collapses redundant whitespace in attribute values and between elements, and strips default attribute values that the browser would apply anyway.
Typical size reductions range from 10% to 60% depending on the SVG's complexity and how much editor metadata it contains. Simple icons exported from design tools often see 40-60% reduction because they carry the most metadata overhead relative to their actual path data. Complex illustrations with many paths and gradients see 10-30% reduction because the majority of the file size is legitimate path data rather than metadata.
The tool shows a real-time preview of the optimized SVG alongside the original, so you can visually confirm that nothing has changed in the rendering. A file size comparison displays the original size, optimized size, and percentage reduction. The optimized output is presented as both a downloadable file and copyable SVG source code, ready to paste into your project.
All processing happens entirely in your browser using the browser's DOMParser — your SVGs are never uploaded to any server, never stored, and never shared. This makes the tool safe for optimizing proprietary icons, confidential diagrams, or any SVG assets you do not want to expose to a third-party service.

Frequently Asked Questions
- What does the optimizer remove?
- XML comments, metadata elements, editor data (Inkscape, Illustrator, Figma, Sketch), empty groups, unused definitions, unnecessary attributes, default attribute values, and excess whitespace.
- Will it change the visual appearance?
- No. The optimizer only removes non-visual data. The SVG will render identically before and after optimization. If you notice any visual difference, it is likely due to a browser rendering quirk, not the optimization.
- How much size reduction can I expect?
- Typically 10-60% depending on the SVG complexity and how much editor metadata it contains. Simple icons from design tools often see 40-60% reduction, while complex illustrations see 10-30%.
- Why should I optimize SVG files before using them on a website?
- SVGs exported from Figma, Illustrator, or Inkscape contain editor metadata, unused definitions, and formatting whitespace that add file size without affecting the visual output. Optimizing removes this invisible data, reducing page weight and improving load times. A 4 KB icon can often be reduced to under 1 KB.
- Is this tool equivalent to SVGO?
- This tool applies a subset of SVGO-style optimizations using the browser's DOMParser: removing comments, metadata elements, editor namespaces, empty groups, and unnecessary whitespace. For the full SVGO plugin suite (path merging, transform collapsing, etc.), use the SVGO CLI or svgomg.net. This tool is ideal for quick cleanup without installing anything.
- Can I paste SVG code directly instead of uploading a file?
- Yes. The tool accepts both file uploads and direct SVG code pasted into the input area. Either method produces the same optimization result.
- Does the optimizer handle embedded fonts and images?
- The optimizer focuses on structural cleanup of the SVG markup. Embedded raster images and font data are preserved as-is. For image compression within an SVG, use the Image Compressor tool on those assets before embedding them.
- Is my SVG data uploaded to a server?
- No. All optimization happens in your browser using the DOMParser API. Your SVG files are never transmitted to any server.
