How to download YouTube video or audio
Kadr prepares a file from a link to an individual video. It works in your browser and lets you choose MP4 video or MP3 audio.
Save a file from a video link
- Open the video on YouTube. Copy the page address or the link from the Share menu.
- Open the Kadr home page, paste the link, and press Continue.
- Check that the title and thumbnail match your video. Choose MP4 video or MP3 audio. For video, select the quality.
- Press Prepare file and wait for processing to finish. Then use the download button to save the file.
Keep the page open while your file is being prepared. Longer videos and higher quality files can take more time to process.
Which format should you choose: MP4 or MP3?
| Format | What it contains | Choose it to |
|---|---|---|
| MP4 | Picture and sound | Watch the video on your device. |
| MP3 | Sound only | Listen to the soundtrack without video. |
Converting to MP3 does not improve the original audio. If you need the picture, choose MP4: you cannot recover the video from an audio file.
What do 360p, 720p, and 1080p mean?
These options set the maximum video resolution. Choose 360p when a smaller file matters most; 720p and 1080p retain more detail when the original supports them. File size also depends on the length and content of the video.
Kadr lists options available for the source and does not increase its resolution. If the original is only 480p, selecting a 720p limit will not turn it into a true HD video.
Find a downloaded video on your phone
Once the file is ready, your browser will offer to save it or start the download. Check the browser's downloads list and the destination folder on your device. If the file opens for playback, use the save option provided by your browser.
If you cannot find the file, check free storage space and the download status. Prepared links are temporary: if a link stops working, check the original YouTube link on the home page again.
What to do when a video will not download
- “Paste a link to a specific YouTube video”
- Use a link to one video. Regular YouTube links, youtu.be links, and Shorts are accepted. Channel links and standalone playlist links are not supported.
- “YouTube rejected the request from this server”
- YouTube has restricted access for the service. Try again later. A video playing in your own browser does not guarantee the server can download it.
- “The server is busy” or “Too many requests”
- Wait for the indicated time or try later. Repeated clicks will not make the file ready sooner.
- The video is unavailable or too long
- Removed and private videos may be unavailable. The service supports videos up to two hours long and does not process ongoing live streams.
Download only videos you own or have permission to save.
