YouTube has been the world's video library for nearly two decades, and "how do I save this video for offline viewing?" remains one of the most common search queries on the internet. The YouTube Tools hub focuses every Ai2Done utility that touches YouTube into a single page — currently anchored by the YouTube Downloader, with adjacent tools for audio extraction, format conversion and subtitle export.
The flagship is the YouTube Downloader: paste a video URL, wait two seconds while we resolve available qualities, pick from 360p through 4K (where the source provides it) or audio-only MP3, and download. We support standard videos, Shorts, livestream replays and unlisted videos, and we always offer the highest quality the source actually provides — including 60 fps, HDR and Dolby Atmos when present. Captions can be exported as SRT so you have a clean transcript for editing or translation.
Common use cases include educators archiving lecture videos before they are unlisted by the uploader, researchers preserving evidence from videos that may be removed by moderation, music fans saving live performances to personal playlists, and travellers caching long videos for offline viewing on flights. Please respect copyright: download only content you own, content licensed for offline use, or content covered by fair-use exceptions in your jurisdiction. YouTube Premium is the right answer for licensed offline viewing within the YouTube app; this tool is for the cases that fall outside that, like archival and research.
Audio extraction is the second-most-common flow. The hub exposes a one-click "MP3" option in the downloader and a separate MP4 to MP3 tool in the Video Tools hub for when you already have the file locally. Bitrates up to 320 kbps are supported when the source contains a high-quality audio track.
If you also use TikTok, Instagram, Bilibili or other platforms, the Social Downloader and Video Downloader hubs collect their respective tools. For post-processing the downloaded file (trim a clip, mute background noise, add subtitles) the Video Editor hub picks up where this collection leaves off.
