How to Compress SVG Files Online Free
Optimize SVG for Web

Why SVG files are larger than they need to be

SVG (Scalable Vector Graphics) is a text-based image format that describes shapes, paths and colors using XML code. Because it is text-based, you can open an SVG file in a text editor and read its contents — and that is exactly why it often contains so much unnecessary data.

Design tools like Adobe Illustrator, Figma, Inkscape and Sketch add a large amount of editor-specific information when exporting SVG files. This includes:

• Comments added by the software (e.g. <!-- Generator: Adobe Illustrator -->)
• Metadata about the document, author and creation date
• Inkscape-specific elements (sodipodi:, inkscape:) that only have meaning when reopening the file in Inkscape
• Adobe Illustrator layer and artboard data embedded in XML namespaces
• Figma node IDs and frame names stored as attributes
• Whitespace — indentation, newlines and spaces that make the file human-readable but add to file size
• Empty group elements left over from the layer structure in the design tool

None of this data is visible when the SVG is displayed in a browser or image viewer. It is purely for the benefit of the design tool. Removing it reduces file size by 30–70% with absolutely no change to how the SVG looks.

What SVG compression removes

Here is a breakdown of what each optimization type does and whether it is safe to apply:

How to compress SVG files online — step by step

Compressing SVGs exported from Figma

Figma is one of the most popular design tools, and its SVG exports are generally cleaner than Illustrator — but they still contain unnecessary data that can be removed.

A Figma SVG export typically includes:

• Frame and layer names as element IDs (e.g. id="Frame-1")
• Clip path definitions that may be empty
• Whitespace indentation for readability

For best results when exporting from Figma:

1. In Figma, select your frame or component
2. In the right panel, click Export → SVG
3. Check "Flatten" if you want simpler path structure
4. Export, then compress with CompressAll to remove remaining whitespace and metadata

Compressing SVGs exported from Adobe Illustrator

Illustrator SVG exports are typically the largest — and the most compressible. Illustrator adds extensive metadata including Illustrator version, document settings, color profiles and AI-specific XML namespaces that are completely unnecessary for web use.

A complex Illustrator SVG can be 60–80% larger than it needs to be. Here is the best export and compression workflow:

1. In Illustrator, go to File → Export → Export As → SVG
2. In the SVG Options dialog, set Styling to "Presentation Attributes" and uncheck "Include Illustrator editing capabilities"
3. Export the SVG, then compress with CompressAll to remove any remaining comments, metadata and whitespace

Using this workflow, a 200 KB Illustrator SVG can typically be reduced to 40–80 KB with no visual change whatsoever.

SVG optimization for websites

Compressing your SVG files before using them on a website has multiple benefits:

• Faster page load: Smaller files download faster, improving user experience and Core Web Vitals scores
• Better SEO: Google's PageSpeed Insights and Lighthouse penalize pages with large, unoptimized SVG files
• Reduced bandwidth: Smaller SVG files use less bandwidth, which matters especially on mobile connections

SVG vs PNG vs WebP for web graphics

For logos and icons, SVG is almost always the best choice. It scales to any size without pixelation, and an optimized SVG logo is typically 2–10 KB compared to 50–200 KB for a PNG equivalent.
