SVG files are blurry and don't play in browser

Hi,

I've been using SVG files from Illustrator to animate in Edge, however, when I preview in browser the images are blurry. Moreover, when the animations are playing in Chrome, sometimes they don't appear at all or seem to take longer to load, but work perfectly in Safari and Firefox yet the images are even more blurred.

Help would be much appreciated,

Thanks in advance!
