About Deflr Video Downloader

Deflr Video Downloader is a browser extension that takes the complexity out of saving Deflr video content. It does the detection work so you can focus on choosing what to download.

Simply visit a Deflr video page. The extension analyzes the page for video streams and populates the popup with available files. Select one and the MP4 appears in your downloads folder moments later.

Every operation is local to your browser. No video or usage data is transmitted externally, ensuring both speed and privacy for every download.
