How to Download YouTube videos free 

There are several ways to download YouTube videos for free, but it's important to note that downloading videos from YouTube without the permission of the copyright holder is illegal in many countries and may also be in violation of YouTube's terms of service. Here are a few methods:

1. Use a YouTube video downloader website: There are many websites, such as SaveFrom.net, that allow you to enter the URL of a YouTube video and download it in various formats, including MP4 and MP3.

2. Use a browser extension: There are browser extensions, such as Video DownloadHelper for Firefox and Chrome, that allow you to download YouTube videos directly from your browser.

3. Use a third-party app: There are many third-party apps, such as TubeMate, VidMate, Snaptube, and InsTube, that allow you to download YouTube videos directly to your mobile device.

4. Use YouTube Premium (for offline viewing only, not for download permanently): YouTube Premium is a paid service that allows you to download YouTube videos for offline viewing through the official YouTube app.

Please be aware that some of the above methods may be illegal or violate YouTube's terms of service, so be sure to check local laws and the YouTube terms of service before proceeding.

It is important to note that downloading videos from YouTube is against the platform's terms of service and may be illegal in some jurisdictions. Additionally, downloading copyrighted content without permission is also illegal. Therefore, it is important to use these apps with caution and only download videos that are allowed to be downloaded under the terms of service and copyright laws.
