Hello I intend to make some WEB pages for Smartphone with a maximum weight of 100Kb per page and if I include a photo, it must be with a quality of 10% or 20%. Since it is for Smartphone, you will not notice difference between a compressed image of 50% to 20%. Unless the image occupies the entire screen of the smartphone hehehe I put that "original" file because it is what I work with, with JPG, images without author rights and downloads from a bank of images. About this post, it is a post or constructive complaint, wanted to see that the compression that Affinity has, still needs to improve, you just have to see the image of Photoshop, which at 10% is almost the same as the original. Greetings and forgive the misspellings, I use a translator.
