What is com.canva.affinity.thumbnail Container?
The ~/Library/Containers/com.canva.affinity.thumbnail folder is a macOS app container associated with Affinity and appears to be used for thumbnail or preview-related sandbox data. People may encounter it while reviewing Library storage, app containers, or disk usage, especially if they use Affinity to open, browse, or export design files.
Safety overview
Status: Mostly safe
This is not a system-critical macOS folder, but it may hold app-specific sandbox data used for previews or temporary working state. Removing it can cause Affinity to lose cached thumbnail data or recreate the container, and in some cases may reset related app state.
Recommendation: Keep it if you actively use Affinity or want to avoid losing thumbnail-related data and settings stored in the container. If Affinity is no longer installed or no longer used, this folder is usually optional and may be removed after quitting the app.
