How to add imported wallpapers
Canvas for Mac lets you bring your own wallpapers into the app so you can keep your desktop library organized locally on your Mac.
To import a wallpaper, open Canvas and click the Import button from the gallery. Choose an image file from your Mac (supported formats include JPG, PNG, and HEIC). After importing, the wallpaper appears in your gallery under the Imported category.
When you import a wallpaper, Canvas securely copies it into its own local folder so it doesn't get lost if you delete the original download.
