A simple approach is to copy the link to the Instagram video and use a browser-based downloader on your phone. I tried SnapTik when I wanted to keep some workout clips available during a trip, and I tested a couple of options first. I like that the basic process is straightforward on my phone. I just copied the video link, pasted it into the tool, and followed the available download option. It was more convenient for me than recording the screen, especially when I wanted a cleaner copy. Different phones and browsers can behave differently, though, so it’s worth checking the saved file afterward.
