TT Downloader is a free Chrome extension developed by lalit. As an add-on in the Browsers category, it provides users with the ability to download TikTok videos and perform mass downloads. With just a click on the yellow download image button located at the top-right of any TikTok video, users can download high-quality videos directly to their computers. Additionally, the extension allows for mass downloading of all the videos from any page on TikTok by accessing the extension's popup from the toolbar.

It's important to note that TT Downloader is an unofficial application and is not affiliated with the official TikTok application or website. The extension requires the "downloads" permission in order to manage and trigger the download of photos and videos, which may prompt a warning message during installation.

Please note that this extension is no longer maintained. Users should keep this in mind when considering its use.
