I noticed lately that when I upload my photos to facebook they instantly look horrible and pixelated. I read an article on photoshelter.com that confirmed I wasn't going crazy. So I thought I would share. Enjoy!
With the largest public repository of photos on the Web, it’s not surprising that Facebook has and continues to employ heavy compression to all of the 250 billion images they store. Facebook never intended to be a high quality archiving service of photos, but rather, photos act as social glue for the social media giant.
But seriously, why do your photos look so bad?
File compression up to 90%
JPG, the dominant photo file format, uses a form of “lossy” compression, which means it throws out picture data to reduce the file size. If you’ve ever played with the “Quality” slider in Photoshop, you probably understand the trade-off in file size and image fidelity.
“Blocky” looking sections of a photo particularly around edge detail or gradients in color are the telltale signs of JPG compression.
The compression is particularly noticeable when a graphic has hard edges like this white type against a graded background.
