About YouTube Downloader

Paste a YouTube link and save the video as MP4, WebM or MKV from 144p to 4K, or just the audio as MP3, M4A, Opus, WAV or FLAC. It sits in the video & audio shelf alongside 27 other video & audio tools, needs no account, and keeps the same behaviour whether you open it here or call it through the REST API.

It works from a link you paste rather than a file you upload. The work happens on our servers. There is nothing to upload, and any file it makes is deleted an hour later — 24 hours if you are signed in. The same operation is available programmatically at POST /v1/media/youtube-downloader.

YouTube Downloader questions

Which videos can I download?

Public YouTube videos and Shorts up to 3 hours long, with each file capped at 2 GB. Private, members-only and age-restricted videos, live streams and whole playlists are refused. Only download videos you own or have permission to save.

What quality will I get?

The best version YouTube has at or below the resolution you pick, from 144p to 2160p (4K). Above 1080p YouTube only serves VP9 or AV1 video, which some older players cannot open inside an MP4; WebM or MKV avoids that.

Does the bitrate apply to every audio format?

No, only to MP3, which is re-encoded at the bitrate you pick. M4A and Opus are the audio stream YouTube serves, copied without re-encoding, and WAV and FLAC are lossless.

Which audio format is fastest?

M4A. It is the AAC audio YouTube serves, copied without re-encoding, so the file is ready as soon as the download ends, and it plays on phones, computers and most players. Opus is copied the same way. MP3 is re-encoded at the bitrate you pick, which adds time on a long video. WAV and FLAC convert quickly but come out many times larger.

How many downloads can I make?

25 a day from one connection without an account. Signed-in accounts use the daily job allowance of their plan instead.

Where is the video processed, and how long is the file kept?

Our servers fetch the video from YouTube and convert it. A download made without an account is deleted about an hour later; one made while signed in is kept for a day.
