I used to think this and then I saw how well webp reduced my website's bandwidth costs compared to optimized jpg or png. I felt a bit left behind at that moment, like I should have been paying attention to these great improvements over the years.
It is great to reduce file size but also the quality drops faster than it does with JPG. I did some testing and could confirm, it is quite documented.
Which I think it might be one of the reasons why Instagram still uses JPG for their images. The rule of thumb is that if your product is picture quality sensitive (like photos in IG) then use JPG, if not then WebP is fine since the compression is higher.
How so? You can literally convert a JPEG to a JXL that contains the exact same information and is 30% smaller.
seems to refer to webp not jxl
