How to Download YouTube Videos (Up to 4K)
Paste the link into fastsaver.io, pick a quality, download. You get a normal mp4, up to 4K when the upload has it. The steps are on the YouTube downloader page; this post covers picking a quality and fixing failures.
reading the grid
Each video tile is a resolution YouTube stores for that video, with its file size. 2160p is marked 4K and 1440p is marked 2K. The filled tile is 1080p, or the top quality when 1080p is missing. A 720p upload tops out at 720p; nothing gets upscaled.
Take 2160p for a TV or for editing, and check the size first. On a phone, 1080p is plenty and saves storage.
audio and shorts
The audio tile at the end of the grid gives you the sound on its own. It is an m4a, not an mp3, and plays in every music app. Details in YouTube to mp3 or m4a. Shorts links paste into the same box and stay vertical; see how to download YouTube Shorts.
when it fails
- “it may be private, age-restricted or removed”. Private, members-only, age-restricted and deleted videos can’t be fetched.
- “couldn’t prepare that download”. Tap the tile again. 4K and 2K are heavier to prepare, so try a lower tile.
- Live streams, until they end and become a normal video.
- Playlists. One video at a time.
Prefer chat? Send the link to @fastsaver_bot on Telegram. Telegram caps bot uploads, so very large youtube files come back as a link.
Where the file lands on a phone is in saving videos on iPhone and Android. Keep what you save for yourself; the legal side is a short read.
