Use PNG when it’s a vector file and JPG when it’s a raster file. For almost all the graphics that you use on Twitch, you should stick to PNG or JPG. This image type should only be used for animations like cheermotes. When to use which image typeĪvoid GIF when you can as you don’t need it in the vast majority of cases. If for some unlikely reason you are over the limit then you should optimize it by resizing to the right size, lowering the quality a bit, or by using a service like Kraken that will losslessly compress it for you. For most of them, it’s 10 megabytes (MB). Twitch is pretty generous when it comes to the file size of images that you can upload.
