Facebook Photo Compression

A couple weeks ago there was a Reddit post on /r/Android recommending Facebook users upload photos via the mobile website rather than the official Android Facebook app. The app reportedly compressed an original 8MP (4.5MB) photo to only 0.6MP (100kB) whereas the mobile website uploaded at 3MP (440kB). For a typical 4:3 ratio photograph, 0.6MP works out to neither dimension having more than 1000 pixels! Viewers on almost all current smartphones and tablets would be looking at an image smaller than their screen size. For a social network so heavily driven by photographs, you would think Facebook would do a better job maintaining some modicum of image quality. Most users probably have no idea their images are being so heavily degraded by uploading via the app. This blog examines the varying quality of Facebook image uploads in an attempt to identify the best option if you must upload to Facebook.
