How to Delete Large Videos on iPhone

A single minute of 4K video weighs 170 to 400MB, roughly 100 times more than a regular photo. Videos are almost always the number one reason your storage fills up, and they tend to be the files you forget about most easily. A few long clips from a wedding, your kid's school recital, or a screen recording you made once to show someone something, and you have quietly burned through dozens of gigabytes. Here is a clear, step-by-step guide: how to track down the heavy videos on your iPhone, how to delete them without losing anything you care about, and how to free up gigabytes fast.

Why videos eat up so much space

A regular iPhone photo weighs around 2 to 4MB. A video, on the other hand, is a stream of dozens of frames every second, which is why the file size balloons. At 4K and 60 frames per second, a single minute can reach 400MB, and that is before we even mention slo-mo clips, which capture at 120 or 240 frames per second and weigh even more. Screen recordings are another classic trap: they run long, save at high quality, and are usually pointless once you have used them a single time.

The takeaway is simple: deleting one heavy video is the equivalent of deleting hundreds of photos. If your goal is to free up space fast, videos are where you should start, not the tiny screenshots. If you landed here because your iPhone storage is full of photos, there is a good chance videos are the real culprits.

Where to see how much space videos use

First, let's get the lay of the land. Go to Settings → General → iPhone Storage. You will get a color-coded chart and a tidy breakdown of what is taking up room on your device. The "Photos" row covers both photos and videos together, and for most people it alone accounts for 50 to 70 percent of all storage.

If you spot a big row called "System Data" and have no idea what it is, that is a completely separate topic, and we cover it in depth in our guide to what System Data is on iPhone. Here we are focusing on the photos and videos category, the one part that is genuinely in your control. Want to know how much space you really have left and how many videos that translates to? Play around with our iPhone storage calculator to see how many minutes of 4K video fit into each capacity.

How to find your largest videos

Apple's Photos app won't let you sort videos by size directly, but there is a quick way to round them all up in one place:

1. Open the Photos app → Albums.
2. Scroll down to the "Media Types" section.
3. Tap "Videos", and every video on your device will appear together in one spot.
4. Pay special attention to the "Slo-mo" and "Screen Recordings" albums that also show up here. These are usually the heaviest and most disposable files of all.

A handy trick: while watching a single video, swipe up on it (or tap the info "i" button). You will see the date, the location, and the resolution, which makes it easy to quickly tell which ones are heavy 4K files and which are small, negligible clips. Always start with the longest and oldest: a video shot two years ago that you have long forgotten about is a prime candidate for deletion.

Back up the important ones before deleting

Before you delete anything for good, it is worth pausing for a moment. You can't reshoot videos of family moments, so the rule is simple: anything you treasure, back it up first, and only then delete it from the device. There are two convenient ways to do this.

The first is transferring to a computer. Connecting with a cable to a Mac or PC lets you copy the heavy videos in their original, full-quality version, with no compression and no reliance on the cloud. We laid out every step in our guide to transferring photos and videos from iPhone to computer. Once the files are sitting safely on your computer, you can delete them from the iPhone with total peace of mind.

The second option is the cloud, either iCloud Photos or Google Photos. Note one important difference: iCloud Photos syncs, which means if you delete a video from the iPhone it is also deleted from the cloud. Google Photos, on the other hand, lets you upload a copy and then remove the local file from the device using the "Free up space" feature, an excellent way to keep everything without it taking up room on your phone.

Delete safely (and what happens in "Recently Deleted")

Now you can delete. Select the videos you want to get rid of and tap the trash icon. Here it is important to understand a point that confuses a lot of people: the videos are not deleted right away. They move to the "Recently Deleted" album and stay there for 30 days as a safety net, and the whole time they still take up storage.

To actually free up the gigabytes, you need to empty the trash: go to Albums → Recently Deleted, tap "Select", then "Delete All". Only after this step does your storage update and the space actually open up. This is also the step people forget. They delete dozens of videos, check their storage, and feel let down that nothing changed. The secret is to always empty "Recently Deleted".

Lower the resolution going forward

After you have cleaned house, it is worth stopping the problem from starting all over again. If you don't truly need cinematic video, dial down the recording quality: Settings → Camera → Record Video, and choose 1080p at 30 frames per second instead of 4K. The difference in file size is enormous. A 1080p clip can take up less than a third of what 4K does, with no meaningful drop in quality when you watch it on your phone screen. You can also turn off 4K for slo-mo separately on the same screen. This might be the single most worthwhile setting you change all year when it comes to saving space.

How Tidy finds and clears heavy videos for you

Going through videos one by one, deciding what is heavy and what is not, and remembering to empty the trash, it works, but it takes time. This is where Tidy saves you all the legwork: the app scans your gallery, automatically sorts your videos by size, and surfaces the heavy recordings, the slo-mo clips, and the duplicates first. You just swipe, right to keep, left to toss, and everything stays in a review pile until you confirm, so no video disappears without your say-so.

Most importantly, all of the detection happens right on the device, with no video ever uploaded to a server. That is how you free up dozens of gigabytes in minutes instead of hours. The same approach works just as well on photos, so if you feel like a general cleanup, we wrote about it in our guide to cleaning up iPhone photos fast, and we also have a complete iPhone storage management guide that ties all the pieces together.
