is it a formatting step that an image goes through when uploaded? I’m tired of converting image after image back into jpg, so if there’s like a step I can take to avoid it being a webp, it would help to know

    whereas png is better for graphics type elements with defined colors and edges?

    The reason for that is rather surprising, but PNGs are basically zipped BMPs with an optional filter step to arrange the pixels in a way that compresses better.

    And that’s why if you give it a photo with lots of details, it’s not very effective and just gives you a rather big file. PNG barely does anything compared to JPEG and other formats. That’s also why it’s great for small things like icons: it decompresses fast and still manages a fairly good compression ratio when a good chunk of the image is transparent or flat background.
