SVG Optimizer
Choose an optimization preset, then shrink your SVG's file size and compare the before and after — free, private, and processed entirely in your browser.
About the SVG Optimizer
SVG files exported from design tools like Illustrator, Figma, or Inkscape are often full of unnecessary metadata, editor-specific namespaces, comments, and unminified path data. Optimizing that markup with SVGO reduces your website's page weight and improves load times, without changing how the vector graphic looks.
Our free online SVG optimizer runs the industry-standard SVGO engine entirely inside your browser. Upload a file, pick a preset, and download or copy the cleaned-up markup — nothing is ever uploaded to a server, so your files stay completely private.
How to Optimize an SVG

Click "Optimize SVG", then download the file or copy the optimized markup instantly.
Frequently Asked Questions
What does SVGO clean up?
It strips unnecessary metadata, editor namespaces, comments, hidden elements, and minifies paths, coordinates, and color names.
Why should I keep the viewBox?
The viewBox attribute is crucial for keeping SVG vectors responsive on websites. Removing it might cause the image to render incorrectly in varying viewport sizes.
Will optimizing change how my SVG looks?
No. SVGO's optimizations are designed to be visually lossless — the Default and Aggressive presets restructure and minify the code without altering the rendered image.
Does it cost money?
No. The SVG optimizer is 100% free to use, with no registration or account required.
