Last Tumblr comment from Ghostvirus: “Tumblr needs to stop reformatting all images as JPGs. I know they’re doing this in an attempt to keep bandwidth usage down, but when a tiny PNG gets reformatted into a JPG that’s 2 or 3 or even 4 times the size the PNG originally was, you’re not doing yourself any favors.”

Stop revealing our feature list before we do! This has been on my to-do list for almost a month, and it’ll happen soon.

We don’t recompress to save bandwidth - we recompress because we resize every image to fit in Tumblr’s narrow columns, and it’s much easier to manage if we can apply the same compression to every image.

But we’re not happy with the image quality, even with images that are better served by the JPEG format, so we’re switching to a different image library. And while I’m in there, I’m going to ensure that PNGs and GIFs (maybe even animated ones) are kept in their original format for better quality and better size efficiency.
