SVG Optimizer

Optimize and minify SVG files by removing editor metadata, comments, hidden layers, and unnecessary attributes. Reduces SVG file size by 40–80% without any visual difference.

FAQ

Why optimize SVGs?

SVGs exported from Illustrator, Figma, or Inkscape contain lots of editor metadata that inflates file size. Optimizing makes pages load faster and reduces bandwidth.

Will optimization change how my SVG looks?

No — the optimizer only removes invisible data. Paths, shapes, colors, and animations are preserved.

What is the difference between SVG and PNG?

SVG is vector-based and scales infinitely without pixelation — ideal for logos and icons. PNG is raster and has a fixed resolution. SVGs are usually much smaller for simple graphics.
