It started with a missing feature: YouTube shows how many videos a playlist has, but not how long it takes to watch them. The site now offers seven tools. 1. YouTube Playlist Length Calculator: paste one or more public playlist URLs to get total duration, video count, average length, and totals at 1x to 2x speed. It supports video ranges and a daily planner with CSV and Excel exports. 2. YouTube Music Playlist Length Calculator: measures public music.youtube.com playlists, including podcasts and long audio. 3. YouTube Playlist Link Extractor: turns a playlist into video titles and watch URLs, ready to copy, export as TXT, or export as CSV. 4. YouTube Timestamp Generator: creates links that start at an exact second for watch pages, youtu.be links, Shorts, embeds, and playlist URLs, all in the browser. 5. YouTube Thumbnail Downloader: shows every available thumbnail size from 320x180 to 1280x720 and saves JPG, WebP, or ZIP. 6. YouTube Profile Picture Downloader: resolves a channel from a URL, @handle, or ID and downloads avatars up to 800x800 as JPG, PNG, or ZIP. 7. YouTube Banner Downloader: downloads channel banners in mobile, tablet, and desktop crops. All tools use public YouTube data, run without login, and document their limits.
