YouTube Downloader

Paste a public YouTube link and fetch it. Then take the whole video with audio and subtitles, a single resolution up to 4K, the audio in your codec, the subtitles on their own, or the full-size poster. The workbench parses the page and muxes the real streams. Public content only.

Workspace

Paste a public YouTube link and fetch it. Then choose a video track, an audio track, and subtitles, and download that exact file, or take a quick preset. Nothing is kept.

Public content only. Private, members-only, and age-restricted videos are not supported.

Link blocked, or want to grab from your own connection?

YouTube video sits behind the browser cross-origin wall, and a server would fetch it from the server address, not yours. So this runs as a small extension inside your own browser: it finds the media on the page and saves it over your own connection.

Cyber24 Grabber

Lists the video, audio, and images loading on any page, and saves them with one click. Runs entirely on your machine; nothing is sent anywhere.

Download .zipDownload .crx

Install the .zip

  1. 1. Unzip the file.
  2. 2. Open chrome://extensions.
  3. 3. Turn on Developer mode.
  4. 4. Load unpacked, and choose the unzipped folder.

The .zip and Load unpacked is the reliable path. Recent Chrome refuses a .crx dropped from disk; the .crx is there only for browsers that still take one.

Then use it

  1. 1. Open the page with the video.
  2. 2. Press play so the stream loads.
  3. 3. Click the Cyber24 mark.
  4. 4. Pick the media and press Save.

Public content only. On YouTube, choose a combined entry for video and sound in one file. Video-only, audio-only, and adaptive streams are labelled separately.
