com.canva.affinity.thumbnail Container
This container stores thumbnail and sandboxed working data used by Affinity on macOS so the app can generate previews and manage related local files.
What is com.canva.affinity.thumbnail Container?
~/Library/Containers/com.canva.affinity.thumbnail is a macOS app container used by Affinity for sandboxed local data related to thumbnail and preview handling. Affinity is a professional design application that combines photo editing, vector design, and page layout tools in one app for creative work on Mac and other platforms. On macOS, container folders like this keep app-specific data separated from other software and may hold temporary working files, internal support data, and settings used while browsing documents or showing previews. Users commonly encounter this folder when reviewing storage usage, troubleshooting app behavior, or cleaning up old library data after removing an app. Removing the container can delete local thumbnail data and other app-managed files inside it, which may force Affinity to recreate them later or lose saved local state tied to that container.

Safety overview
Status: Mostly safe
This is user-library data for Affinity, not a macOS system component. Deleting it will not damage macOS, but it can remove thumbnail previews, reset container-held app state, or clear local files that Affinity expects to find. The folder name uses the Canva-owned bundle namespace com.canva.affinity, which is consistent with Affinity being part of Canva. If you still use Affinity, keep the folder unless you are specifically troubleshooting corrupted preview data or reclaiming space after uninstalling the app.
Recommendation: Keep this folder if you use Affinity regularly, because the app may rely on it for previews and sandboxed local state. If Affinity has been removed from your Mac, you can delete this container to free space, and the main effect is losing any remaining local thumbnail or container data tied to the app. If you are troubleshooting, quit Affinity first so any needed files can be recreated cleanly on the next launch.
