Weblow’s hosting does indeed gzip-compress SVG files! What a godsend! This may be common knowledge, but posts here and on the Wishlist, through 2018, showed the opposite:
Some quick tests I ran:
Original EPS: 3,900 KB
Exported SVG: 803 KB
Exported PNG: 245 KB (2500 x 1250 pixels)
Live Webflow Site: 104 KB
The image was tricky (lots of small circles), so I’d stuck to a slightly blurry PNG. But, with an SVG, I’ve dropped ~50% of wasted bandwidth!
Not sure how many it will help, but hopefully this can clear up confusion for Webflow-curious users.
