# Thumbnails & Public Assets

Platforms publish some images openly, such as the thumbnail of a public video, and creators often need them for previews, playlists or reference. YouTube recommends uploading thumbnails at 1280 × 720 pixels, a 16:9 aspect ratio. Respect the creator's copyright when you reuse an image.
