* The export dialog has options to write text as paths and filters as SVG filters so that all browsers display them correctly.

Safari can display vertical text with limited support for text orientation.

Browsers may also have other bugs when displaying SVG. You should always test your SVGs on all browsers to ensure that they are rendered correctly.

SVG with KeyshapeJS Animations

KeyshapeJS Javascript animations are supported by all browsers, which can display SVG. It means that Chrome, Firefox, Safari, Edge, and IE9-11 can play them back.


Although animations are supported by all browsers, they still may have bugs related to SVG rendering, so you should test your animations on all browsers.

SVG with CSS Animations

CSS Animations work in modern browsers. Some properties work better than other.

* Keyshape export option 'Write motion paths as transforms' will write curved motion paths as CSS transforms, so they work in all modern browsers (Safari and the old Edge).

** Only Chrome 53 and Edge 75 or later supports CSS animation of path shape data (CSS 'd' property), but it may use a non-standard syntax. It is recommended not to use CSS path shape animations until issues related to it are resolved.

Safari has a bug, which means that CSS animations inside symbols won't work.

Browsers also have other bugs related to CSS animations. You should always test your CSS animations on all browsers to check that they display properly.
