Transloadit can handle uploads of your users directly.
The /upload/handle Robot receives uploads that your users throw at you from browser or apps, or that you throw at us programatically.
Allows you to specify a set of meta data that is more expensive on cpu power to calculate, and thus is disabled by default to keep your Assemblies processing fast. You can add "has_transparency": true in this object to extract if uploaded images contain transparent parts.
Our /upload/handle Robot can be used in combination
with other Robots, to create powerful workflows unique to your use case.
Here are a few example scenarios, and the required the Assembly Instructions to implement them.
You can also try demos of these examples right here, live on our website.
