I am little confused why Shopify does not allow uploading SVG files as an image banner for my website. On my images I have a lot of designs elements and the png. jpg. webp. and giff. files are too blurry, so is there a possibility to upload SVG files for images? I know there is the possibility to upload a specific Image to the assets and add it to the code, but I often change my images, so it would be easier if I can upload SVG files to the customize page. I hope you can help us!
Sorry you are facing this issue, it would be my pleasure to help you.

As you can see, this banner is really blurry. Most important for me is that I can upload SVG files in genral to my customize page. Now only png. jpg. webp. and giffs. are allowed.
