On an average, this kind of metadata occupies 16% of size of the JPEG file. Ho ho. You think that's bad? Back in 2011, Tumblr didn't strip metadata from avatar images. That results in some funny files, like this one: http://28.media.tumblr.com/avatar_c5ee131b70d0_40.png http://28.media.tumblr.com/avatar_c5ee131b70d0_40.png That PNG has a 3325 byte IDAT chunk, and a 106022 iCCP chunk. The metadata is 3188% bigger than the image itself. Personally, I think websites should strip metadata from thumbnails and resized images, but should also let you download the original, unmodified image, complete with original filename. Why? Instagram and others always recompress and strip metadata when you submit an image. This results in shitpics-- images so mangled by recompression that they look like visual gravel: https://theawl.com/the-triumphant-rise-of-the-shitpic-e25d8e5af9bc#.bkxh5tln3 https://theawl.com/the-triumphant-rise-of-the-shitpic-e25d8e... This is a complete own goal, there's no technical reason this has to happen. Digital files aren't supposed to decay! And, of course, stripping authorship tags would make the dream of automated attribution impossible: https://eev.ee/blog/2016/08/15/attribution-on-the-web/ https://eev.ee/blog/2016/08/15/attribution-on-the-web/
