How to Find and Delete Large Videos on iPhone Storage

On this page

To delete large videos on iPhone, start in Settings > General > iPhone Storage: it ranks apps by size and lists big Messages attachments largest first. For clips you shot, open the Videos album in Photos, play each one and tap the trash icon. Deleted videos stay in Recently Deleted for 30 days and keep using storage until you empty that album (Apple Support). The Photos app itself cannot sort videos by file size.

The good news: iOS already gives you tools to surface the biggest offenders. Start there, clear the obvious wins, then do a faster manual pass on the rest. Here's the exact path.

Step 1: See what's actually using your storage

Before deleting anything, look at where your space is going.

1. Open Settings.
2. Tap General.
3. Tap iPhone Storage.

Give it a moment to load. At the top you'll see a colored bar breaking down storage by category (Photos, Apps, Media, System Data, and so on). Underneath is a list of apps sorted by how much space they use. Photos usually sits near the top, and most of that is video.

iOS also shows Recommendations here: things like "Review Large Attachments" or offloading unused apps. These are a quick way to reclaim space without touching your camera roll at all.

Step 2: Use "Review Large Attachments" for Messages videos

A surprising amount of video clutter lives in your Messages threads, not your Photos app: clips friends sent you, memes, and screen recordings.

1. In Settings > General > iPhone Storage, tap Messages.
2. Tap Review Large Attachments (or Documents & Data > Top Conversations).
3. You'll see attachments sorted largest first. Tap Edit, select the videos you don't need, and tap the trash icon.

Deleting these removes them from the conversation and frees the space immediately. This is one of the fastest wins because the items are already ranked by size for you.

Step 3: Find your largest videos in the Photos app

For videos you actually shot, head to Photos. Apple keeps every video in one place:

1. Open Photos.
2. Tap Albums (or scroll to the Media Types section).
3. Tap Videos.

This album collects every video in your library, and it auto-updates as you record more. It's an honest, built-in filter, not an algorithm guessing what you want.

Tip: turn on Optimize iPhone Storage (Settings > Photos) if you use iCloud Photos. It keeps full-resolution videos in iCloud and lighter versions on the device, which reduces local pressure without you deleting anything. It's not a substitute for clearing junk, but it helps.

Step 4: Watch before you delete

Here's where deleting videos gets tricky. Unlike a blurry photo you can judge in half a second, a video needs context. Is this the good take of the birthday speech or the one where the camera shook? Did you already save this slow-mo somewhere? You often can't tell from the thumbnail alone. You have to actually watch it, or at least scrub through it.

In the Photos app you can tap a video to play it, then drag the small filmstrip at the bottom to scrub. Once you're sure, swipe up on the video or tap the trash icon to delete it.

When you delete in Photos, the video moves to Recently Deleted, where it stays recoverable for 30 days before it's permanently removed. If you want the space back instantly, go to Utilities > Recently Deleted, tap Select, then Delete All. For more on how that safety window works, see where deleted photos go on iPhone.

A faster manual pass: swipe through your videos

Apple's tools are great for finding the biggest files. But once you've cleared the obvious giants, you're often left with dozens of smaller-but-still-chunky clips: duplicate recordings, false starts, screen recordings you forgot about. Tapping into each one in the Photos app, watching, backing out, and deleting one at a time is slow.

This is the gap Pixtide is built to fill. It's a free, ad-free swipe app: each video fills the screen and you swipe right to keep, left to delete, or down to decide later. Crucially, videos play inline with a scrub bar, so you can preview and skim through a clip right on the card before deciding: no tapping in and out. Many swipe cleaners are photo-focused or treat video as an afterthought; judging video properly is one of Pixtide's core strengths.

A few things to be honest about:

• Pixtide does not rank videos by file size or use AI to guess which ones are "bad." You decide every clip. That's the point. For pure size-ranking, lean on Settings as described above.
• Swiping only marks a video. Nothing is deleted until you review your marked items on a confirmation screen and approve.
• Confirmed deletes use Apple's PhotoKit, so they land in Recently Deleted for 30 days: exactly like deleting in the Photos app.

So the smart workflow is: use Settings to nuke the storage giants, then use a swipe pass to quickly clear the long tail of smaller clips. If you want a deeper walkthrough of the video-only cleanup flow, see cleaning up videos on iPhone and using a swipe app to delete videos.

Quick reference

A few honest caveats

Deleting videos from your iPhone won't free space the instant you tap delete. They sit in Recently Deleted for 30 days unless you clear that album manually. If you use iCloud Photos, deleting on one device deletes everywhere, so make sure anything important is backed up first. And remember that videos are just one kind of clutter; screen recordings, screenshots, and bursts add up too, which is worth understanding if you're doing a full cleanup (see the types of photo clutter).

Start with Settings to find the giants, watch before you delete, and lean on a manual swipe pass for everything in between. No algorithm decides for you. You stay in control of every clip, and Apple's 30-day safety net is there if you change your mind.

Frequently asked questions

How do I find the biggest videos on my iPhone?

The Photos app cannot sort by file size, so start in Settings, General, iPhone Storage. It ranks apps by the space they use, and under Messages, Review Large Attachments lists videos and files largest first. For clips you recorded, open the Videos album in Photos and check long clips and 4K clips first, because length and resolution decide a video's size far more than anything else.

How much storage does a minute of iPhone video use?

The figures shown in Settings, Camera, Record Video put one minute at roughly 60 MB in 1080p at 30 fps and roughly 400 MB in 4K at 60 fps with the High Efficiency format. Slow-motion and ProRes clips use far more. That is why a handful of long 4K videos can outweigh thousands of ordinary photos on the same iPhone.

Why is my iPhone storage still full after deleting videos?

Deleted videos move to Recently Deleted and keep using iPhone storage for up to 30 days. To free the space now, open Photos, go to Utilities, unlock Recently Deleted with Face ID or your passcode, tap Select and delete the videos there. Once they leave Recently Deleted they are gone for good, so only do this when you are sure nothing in the album is needed.

Can I make a video smaller on iPhone instead of deleting it?

Partly. Trimming a clip in the Photos editor and tapping Save Video keeps the full original so the edit can be undone, which saves little space. Choose Save Video as New Clip instead, then delete the original. With iCloud Photos on, Optimize iPhone Storage in Settings, Photos keeps full-size originals in iCloud and smaller copies on the phone. For future clips, record in 1080p rather than 4K.

If I delete a video from my iPhone, is it deleted from iCloud too?

Yes, when iCloud Photos is on. The library is shared across your iPhone, iPad, Mac and iCloud.com, so deleting a video on one device deletes it on all of them, and it waits in Recently Deleted for 30 days. To keep a video while freeing phone space, turn on Optimize iPhone Storage instead of deleting, or copy the clip to a computer or drive first.

Is there an app to review and delete iPhone videos faster?

Yes. Swipe apps show one clip at a time, so each keep-or-delete call is quicker than tapping in and out of the grid. Pixtide is a free swipe app that plays videos inline with a scrub bar, and a swipe only marks a clip until you confirm on a review screen. It does not sort videos by file size, so use Settings to find the largest files first.
