SVG Optimizer

Requires server processing

Paste SVG markup or choose an .svg file, and get back a smaller, functionally identical file.

Overview

        

            
SVG files exported from design tools like Illustrator, Figma, or Sketch often carry a lot of dead weight: editor metadata, XML comments, unnecessary precision on path coordinates, redundant groups, and unused IDs. None of that affects how the image renders — it's just bytes the browser has to download and parse for no visual benefit.

            
This tool runs SVGO, the standard open-source SVG optimizer, to strip that overhead while preserving the visual output. Unlike this site's other image tools, the input here is a small text payload rather than a large binary file, so this runs as a quick server-side text transformation rather than a file-upload pipeline — there's no meaningful client-side alternative, since no maintained browser port of SVGO exists.

        

      


      

        
Examples

          

            
Optimizing an icon exported from a design tool

            
<svg xmlns="http://www.w3.org/2000/svg" width="24" height="24"><!-- Generator: Adobe Illustrator --><g id="Layer_1"><rect x="0.000000" y="0.000000" width="24" height="24"/></g></svg>

            
<svg xmlns="http://www.w3.org/2000/svg" width="24" height="24"><rect width="24" height="24"/></svg>

          

      


      

        
How It Works

        
    
            
  1. Paste SVG markup into the text box, or choose an .svg file to load its contents automatically.
    2. 
            
  2. Click Optimize.
    3. 
            
  3. Review the optimized markup and the before/after size shown.
    4. 
            
  4. Copy the result or click Download to save it as a file.
    5. 
        

      


      

        
Use Cases

        

            

              
Cleaning up icons before committing them to a codebase

              
Strip editor cruft from exported SVG icons so the version-controlled files stay small and readable.

            

            

              
Reducing page weight from inline SVGs

              
Smaller SVG markup means less HTML to download and parse, especially when several icons are inlined directly on a page.

            

        

      


      

        
Tips

        
    
            
  • Optimization is lossless for how the image renders — only redundant markup is removed, not visual detail.
    • 
            
  • If an SVG relies on specific IDs for CSS or JavaScript hooks elsewhere on your page, double-check those IDs survive optimization before replacing the original file.
    • 
            
  • Very complex SVGs (many paths, gradients, filters) benefit the most, since there's more redundant markup to strip.

FAQ

        

            

      

        

          
        

        

          
Yes. SVGO, the library this tool uses, only runs in Node.js — there's no maintained browser version — so the markup is sent as text, optimized, and the result returned. It's never stored.

        

      

      

        

          
        

        

          
No. Optimization removes redundant markup (comments, metadata, excess coordinate precision, unused definitions) without changing the rendered output.

        

      

      

        

          
        

        

          
Yes, 500,000 characters — far larger than a typical icon or illustration.

        

      

      

        

          
        

        

          
The tool reports a parse error rather than guessing — fix the markup and try again.
