| Everything else |
On a Mac, other pictures — heic, avif, psd, icns, camera raw — are drawn by the system's own decoder; everywhere the app draws png, jpeg, gif, webp, tiff, bmp and ico itself. stl, usdz, rar, xls, ods and odp have no reader here, and open in hex.
Every one of these parsers runs on your machine. Nothing is sent anywhere to be rendered — see your data stays here.
Next: tabular.
