Image Manipulation
Images come in all sorts and sizes, but your users must be able to view them on any platform or device. You may also want to manipulate these images even further, to make everything look picture perfect for you and your users. Transloadit can convert images into various formats, or resize, crop and (auto-)rotate them. We can also apply watermarks and other effects, or optimize images to reduce their size without loss of quality, and much more.
Robots
At Transloadit, we call our features Robots because you can link them together to create encoding pipelines unique to your use case.

merges several images into a single spritesheet
-
/image/optimize
