How to Enable Full-size Thumbnail Previews of SVG Files in Finder

Thank you for the quick answer! Please, try to download any of these icons. Do you still have that full-sized thumbnails rendered from those icons? I guess that icons/svgs with defined dimensions would still look small even in your setting.

In previous versions of macOS I had exactly the same look you have for all kinds of svgs. On Windows you can install SVG Explorer Extension to get the result I pursue.

Thank you! I can achieve such a result just saving my icons as responsive (in Adobe Illustrator you can do it). But the point is that in earlier macOS versions I just downloaded icons like these and they were rendered full-size. Icon Manager apps can do it as well. For my job I need the icons to be the given width and height. Looking for a particular icon in a folder it is essential to have full-size thumbnails and I could do so in previous version of mac OS. In Catalina there is rendering problem. Why not just build in an option how I'd like the previews to be rendered..?

"24px is full size" – Right! But I wish that content of this icon fullfill the whole available canvas space that I defined in View Options > Icon Size. I could do it in OS X 10.11 El Capitan and macOS 10.12 Sierra having Gapplin installed.

Yes, I know. I didn't use Gapplin for previews. Having Gapplin installed made it possible to preview icons full-size in Finder as well as in Quick Preview. I did it back in 2016 like described here and it worked very well until I switched to Catalina.

In Quora forum that article has at least 9 upvotes and over 5K views that makes me believe it worked for others too. Writing it here I hope other folks would also like to have Apple build in this option in next updates maybe :) Or maybe someone could write a small extension for Finder to enable this functionality like it was done for Windows.

That is the point: In previous versions of macOS I could preview those icons as I described above, therefore I look for the solution to be able to preview those svgs full-size on macOS Catalina :)
