FAQ

YouTube Thumbnail Downloader FAQs

Common questions about how YouTube Thumbnail Downloader works and what to expect from the current AiFolder implementation.

?What is the highest YouTube thumbnail resolution?

The common maxresdefault variant is typically 1280 × 720 when the video has a max-resolution thumbnail available.

?Why can maxresdefault be unavailable?

Older videos, low-resolution uploads, or videos without a generated max-resolution thumbnail may not expose that variant.

?Can I reuse a thumbnail from a video I do not own?

Downloading an image does not grant reuse rights. Follow copyright, licensing, and platform rules for the thumbnail you plan to use.
