Frequently asked questions
Is it legal to download YouTube thumbnails?+
Thumbnails are served from a public CDN and downloading them for personal reference is generally fine. Republishing a thumbnail — especially commercially — is governed by copyright and YouTube's Terms of Service. When in doubt, get permission from the video's creator.
Why is the maxresdefault image missing for some videos?+
YouTube only generates the 1280×720 maxresdefault image for videos uploaded in HD. Older or low-resolution uploads stop at hqdefault (480×360); SwiftTooly automatically falls back to the largest size that actually exists.
Does this work with YouTube Shorts?+
Yes. Paste a /shorts/VIDEO_ID link and the tool extracts the ID the same way it does for regular videos. The same thumbnail sizes apply.
Do you upload the URL or the thumbnail anywhere?+
No. The video ID is parsed locally and your browser fetches the image directly from YouTube's i.ytimg.com CDN. SwiftTooly never sees the URL or the image.
