SVG Optimizer Online

What Is SVG Optimization?

SVG optimization is the process of reducing the file size of an SVG (Scalable Vector Graphics) file by removing data that does not affect its visual output. This SVG optimizer uses SVGO — the industry-standard SVG optimization library — to strip comments, metadata, editor artifacts, and redundant numeric precision from your SVG code. Smaller SVG files load faster on the web and reduce bandwidth usage. All processing happens locally in your browser.

How to Use SVG Optimizer

1. Paste your SVG code into the Input area, or click Load Sample to try an example.
2. Configure options: toggle Remove Comments, Remove Metadata, and set Float Precision.
3. Click Optimize to run the optimization.
4. The optimized SVG appears in the Output area with the size reduction percentage shown.
5. Click Copy to copy the result to your clipboard.

Features

• Powered by SVGO — the most widely used SVG optimization library
• Remove comments — strip XML comments from the SVG source
• Remove metadata — delete editor-generated metadata elements
• Configurable float precision — control decimal places for coordinates and sizes
• Size reduction display — shows input/output sizes and percentage saved
• Privacy-first — all processing is local, nothing is uploaded

FAQ

What is SVG optimization?

SVG optimization reduces file size by removing unnecessary data such as comments, metadata, editor artifacts, and redundant attributes, while preserving the visual appearance of the graphic.

Will optimizing an SVG change how it looks?

In most cases, no. The optimizer removes data that does not affect rendering. The "Remove ViewBox" option is the main exception — disabling it is recommended if your SVG needs to scale responsively.

What does the float precision setting do?

Float precision controls how many decimal places are kept for numeric values in the SVG (coordinates, sizes, etc.). Lower precision means smaller file size but slightly less accurate curves. A value of 2–3 is usually a good balance.

Is my SVG data sent to a server?

No. All optimization runs entirely in your browser using the SVGO library. No data is uploaded to any server.
