How to Make SVG Files Smaller Without Losing Quality

SVG files are great for logos, icons, and website illustrations. They stay clear on phones, laptops, and large screens without becoming blurry.

Still, the file itself may contain far more code than the image needs.

Open an SVG exported from Figma, Illustrator, or Sketch in a text editor, and you may find editor notes, hidden layers, empty groups, repeated styles, and very long numbers. Most of that information does nothing once the image appears on your website.

Why clean up your SVG files?

A single SVG probably won’t slow down an entire website. Problems start when a page loads many icons, logos, or detailed illustrations at the same time.

Exported SVGs may include:

• Data added by the design software
• Groups with no visible content
• Hidden shapes that are never displayed
• Styles repeated across several elements
• Default settings that do not change the image
• Coordinates with unnecessary decimal places

For example, a position stored as 12.3456789 may look the same when shortened to 12.3. That small change saves only a few characters, but the difference grows across hundreds of paths and points.

Smaller SVG files mean less code for the browser to download and read. They are also easier for developers to inspect and maintain.

Compress SVGs in your browser

The Online Web Toolkit SVG Compress Tool cleans unnecessary code from your SVG files using SVGO.

There is nothing to install. Add your files, wait for the tool to process them, and review the results before downloading.

The work takes place inside your browser. Your SVG files stay on your device instead of being uploaded to a remote server.

Key Features

• Process a complete icon set together

  
  

  Compressing files one at a time becomes annoying when you have a folder full of icons.

  
  

  You can add several SVG files in one batch. The tool processes them together, making it useful for app icons, website graphics, logos, and design system assets.

• Adjust the precision when needed

  
  

  SVG shapes rely on numerical values for their size, curves, and position. Design software sometimes saves those numbers with more detail than a browser needs.

  
  

  The precision control lets you decide how many decimal places to keep.

  
  

  Lower precision can create a smaller file. Higher precision keeps more of the original path data. Try a setting, check the preview, and change it when the result does not look right.

• Compare both versions

  
  

  The preview places the original SVG beside the compressed one. You can check the shapes, spacing, lines, and colours before saving anything.

  
  

  Compression does not always create a smaller file. In the rare case where the processed version becomes larger, the tool keeps the original file instead.

• Reduce your SVG file sizes

  
  

  Add your SVG files to the compressor, compare the results, and download the smaller versions.
