Of course, you can also use any of the web based options mentioned above if you prefer.
Next, you need to tap the download button, and then select the option to 'Export video To Camera Roll'.
Just copy the URL of an Instagram post from the Instagram app an then paste it into Blaze. One option is Blaze: Browser & File Manager. The security restrictions in place with iOS mean that being able to save videos from Instagram is not quite as straightforward as on the desktop, but it's still not too tricky – all you need is the right app. Other web-based services that work in a similar way include DownloadGram and Download Instagram Videos.
Hit the DreDown button, wait while the video is analysed and then download it. Copy the URL from the address bar of your web browser, switch to the DreDown page, click the Instagram link at the top, and then paste the URL into the text bot on the DreDown page. To make use of the site, you'll first need to visit Instagram and load up the video you're interested in.
