SVG Viewer
View SVG code with live preview, optimize and minify SVG, convert to data URI for CSS embedding. See SVG dimensions and file size comparison. Free online SVG viewer and optimizer.
Why Use an SVG Viewer & Optimizer?
SVG files often contain unnecessary metadata, comments, and whitespace that bloat file size. Our SVG Viewer lets you preview SVG code visually, optimize it by removing unnecessary attributes and minifying, and convert it to a data URI for direct CSS embedding — all in one tool.
Key Features
- Live SVG preview with rendered output
- SVG optimization: remove comments, metadata, unnecessary whitespace
- Convert SVG to data URI for CSS background-image
- Copy optimized SVG code or data URI
- Show SVG dimensions, original vs optimized file size, and savings
How It Works
- Paste SVG code or upload an SVG file
- See the rendered preview and SVG info (dimensions, file size)
- View the optimized SVG and data URI output
- Copy the optimized SVG or data URI for use in your projects
Technical Details
This tool uses DOMParser to parse and validate SVG code. Optimization is performed client-side using regular expressions to strip unnecessary content. The data URI conversion encodes the SVG using URL-safe percent encoding for maximum compatibility with CSS and HTML.
Frequently Asked Questions
What does SVG optimization do?
SVG optimization removes unnecessary content like XML comments, declarations, doctypes, editor metadata, excessive whitespace, and empty attributes. This reduces file size without changing the visual output.
What is a data URI and why would I use it?
A data URI encodes the SVG as a URL-safe string that can be embedded directly in CSS using background-image or in HTML img tags. This eliminates extra HTTP requests for small icons and graphics.
