The particular set of Image formats that you can use can depend on the version of the underlying encoding tools that Transloadit uses for the following Robots:
Transloadit recommends having:
imagemagick_stack: "v3.0.0" in these Robots'
Assembly Instructions. We are intimately aware of how important continuity is for our
customers, so stack version upgrades are always opt-in.
Stack versions are typically supported for many years before we start issuing deprecation warnings
(for example: we had been supporting
"v1.0.0" for 11 years before we deprecated it).
