No account or upload controlsHow it works
- Paste a standard YouTube or youtu.be video link into the URL field.
- The frontend validates the URL shape and identifies the local video ID.
- Review maximum, high, and medium quality cards with resolution and aspect-ratio details.
- Select a download state; external thumbnail retrieval is deliberately not connected in this frontend-only implementation.
How the video ID is identified
A regular watch link places its identifier in the v query parameter, while a short link places it in the first path segment. The browser URL parser reads those parts without loading the video page.
youtube.com/watch?v=VIDEO_ID -> query parameter
youtu.be/VIDEO_ID -> path segment
A production downloader would then need to request external image files. That integration is outside this UI-only scope, so the quality cards remain explicit preview and control states.
FAQ
Does this frontend fetch thumbnails from YouTube?
No. This implementation is intentionally the frontend interface only. It validates common YouTube URL shapes and presents quality, resolution, preview, and download states without connecting to YouTube or another external service.
Which thumbnail sizes does the interface represent?
It presents maximum-resolution, high-quality, and medium-quality cards. Common labels are 1280 by 720, 480 by 360, and 320 by 180, although the images actually published for a video can vary.
Why might maximum resolution be unavailable?
Not every uploaded video has every thumbnail variant. Older, low-resolution, live, short-form, or still-processing videos may expose a smaller image set when a real retrieval service is connected.
Can I use another creator’s thumbnail?
A thumbnail can be protected by copyright or platform rules. Download or reuse images only when you own them, have permission, or have another lawful basis, and do not imply endorsement.
What YouTube links can the URL field recognize?
The local URL parser recognizes standard youtube.com watch links and short youtu.be links, plus common path-based YouTube URL shapes. It extracts the video identifier only; it does not contact the video page.
