If we're making breaking changes to PDFs, I'd love if the committee added a modern image format like JPEG-XL. In my experience, most disk usage of PDFs comes from images, not streams.
I keep a bunch of comics in PDF but JPEG-XL is by far the best way to enjoy them in terms of disk space.
Odd you should say that, as that's exactly what they've been discussing
No it's not. This article is about proposing Brotli as another possible '/Filter' for stream objects, like content streams (page drawing commands). Images are streams too, but unless you mean compressing raw pixel bytes in Brotli, there's no mention of a JPEG-XL or WEBP filter.
well, not mentioned in this specific article. But JPEG-XL support is something they're working on [1].
