How to Download Reddit Videos on iPhone

Reddit stores video and audio for a post as two separate files on the backend, which is why a plain screen recording or a half-working downloader often gets you a silent clip. Grabio sidesteps that by handing the post link to cobalt.tools, a tool built to merge Reddit’s split audio and video tracks back into one file automatically.

Why Reddit videos are trickier than most

Most platforms serve one combined video file. Reddit’s own video player (v.redd.it) streams the picture and sound separately and stitches them together client-side in the app. That’s fine when you’re watching inside Reddit, but it means a naive save grabs the video with no sound. cobalt.tools handles the merge on its end, so what you download actually has audio.

Steps to download a Reddit video on iPhone with Grabio

1. Add Grabio to your iPhone, a free Apple Shortcut with no login and no App Store step.
2. Open the Reddit post with the video, tap the Share icon below it.
3. Tap Grabio in the share sheet, or Copy Link and open Grabio manually.
4. Grabio recognizes the Reddit link and opens cobalt.tools in Safari with it pre-loaded.
5. Tap Download. cobalt.tools merges the audio and video tracks and gives you one file to save to Photos or Files.

What this fixes versus Reddit’s own save option

Reddit’s in-app share sheet sometimes offers a save-video option, but it’s inconsistent across post types and can drop the audio track entirely depending on how the post was uploaded. Routing through Grabio and cobalt.tools gets a consistent result regardless of whether the post is a native Reddit video, a crosspost, or a link post with embedded video.

Is it private and free on iPhone?

No account, no login, no cap. Grabio’s server only reads the link to identify it as Reddit and redirects your browser, it never touches the actual video or audio data. cobalt.tools does the fetch and merge on its own infrastructure. Use this for content you have a right to keep a personal copy of, not to reupload someone else’s post elsewhere.

Download Reddit videos on iPhone: FAQ

Why did my downloaded Reddit video have no sound before I tried this?

Because Reddit stores audio and video as separate streams, and whatever method you used before probably grabbed only the video stream. cobalt.tools specifically merges both, which is the whole reason this route works better than a generic downloader.

Does this work on old.reddit.com and mobile-shared links the same way?

Yes, as long as the link points to a specific post with a video, Grabio detects it as Reddit regardless of whether it’s a v.redd.it link, a reddit.com/r/… post link, or a shortened share link from the app.

Can I get a GIF-style Reddit video without sound on purpose?

cobalt.tools generally gives you the full file with audio if the post has any, since it’s built to preserve what’s actually there. If the original post genuinely has no audio track, the download naturally comes out silent too.
