Ostagram is a fun image mixing tool that lets you transform the style of your images and photos. Simply upload your image, and then select from a huge number of styles and artworks to fuse into your image. For example, you can upload a selfie and then select the style of Van Gogh’s “Starry Night”, turning your photo into an artistic portrait painting. Ostagram is free to use, but there is a processing queue for free users, so you’ll have to wait a few minutes for your image mix to be completed.
