[QUOTE="WayneF, post: 537259, member: 12496"] Yes absolutely, these fuzzy artifacts around sharp edges are unequivocally caused by excessive JPG compression, caused by using a JPG Quality factor too low. Choose a high JPG Quality factor to eliminate them (starting from a new original, these cannot be removed once present). That is one type of JPG artifacts. Another type of JPG artifact is 8x8 pixel "blocks" shown in plain areas, like sky or walls. I don't see those here, but neither of those artifact effects are pixelization, they are instead JPG artifacts caused by excessive JPG compression, caused by using a JPG Quality factor too low. Start over from the original, and choose a decently high JPG Quality factor when Saving, and all of this will disappear. Quality is a good thing, don't be stingy with JPG Quality. :) [/QUOTE]
