SVG Optimizer Online
Upload an SVG file or paste its code, choose your cleanup options, and download the result. Compare the original and optimized file sizes to see what changed. No account is needed for this tool.
Use Upload File for a local SVG, or Paste Code for SVG markup from your editor. The input limit is 10 MB.
The result shows original and optimized byte sizes. Savings depend on the input and options; an already compact file may stay the same size or grow.
Optimization runs in your browser. The site records usage events such as file sizes and processing time; local processing does not mean the site has no analytics.
How to Optimize an SVG
- Keep the original. Save a copy before changing an asset used in a website or application.
- Load the SVG. Choose Upload File or paste the complete SVG markup in Paste Code.
- Choose options and click Optimize SVG. Start with higher number precision if the artwork has small details. Enable Preserve animation structure for animated or script-controlled artwork.
- Download and compare. Open the downloaded SVG beside the original in its intended application. Check appearance, text, animation, and any CSS or JavaScript interactions before replacing it.
Choose the Cleanup Your File Needs
These switches remove metadata elements and XML comments. Keep a source copy if those fields contain notes, licensing information, or details needed by your design workflow.
Allow the optimizer to combine compatible paths. Disable this when you need to keep separate shapes available for later editing or animation.
Choose between zero and five decimal places. Lower precision can shorten numeric values, but may change small details. Compare the result at the sizes where it will be displayed.
This setting avoids geometry changes, numeric rounding, and removal of hidden or empty elements. It takes priority over path merging and number precision. Check the resulting animation in your application.
Frequently Asked Questions
How much smaller will my SVG be?
There is no fixed reduction. Editor metadata, comments, numeric precision, and the existing path structure all affect the result. Use the measured sizes shown by the tool to decide whether to keep it.
Does optimization guarantee the same appearance?
No. Optimization can change the structure and precision of an SVG. Check the downloaded file at its intended size, especially for detailed artwork, filters, animations, and elements controlled by external code.
Can I preview the optimized artwork here?
This tool reports file sizes and provides a download. To inspect the artwork, open that file in your browser or use the SVG code editor to view and adjust its code.
What about IDs and accessible labels?
Keep the original and check labels and references in the final page. Cleanup can remove hidden or empty elements that your own code uses. Enable Preserve animation structure when you need to retain those elements, and test any external scripts or styles.
Does this replace gzip or Brotli?
No. This tool changes SVG markup. A web server can separately compress the file during transfer. The sizes shown here are the SVG file sizes, not a measurement of compressed network traffic.
