How to find and delete the largest videos on iPhone

A few long videos can take more space than thousands of photos. A ten-minute clip in 4K can weigh several gigabytes. If your iPhone is full, videos are the fastest place to look.

The catch is that the Photos app does not tell you which videos are the biggest. This guide shows what iOS gives you, how to work around the gaps, and what to do once you have found them.

Why videos take so much space

Size depends on how the video was recorded. Apple lists approximate figures in Settings > Camera > Record Video, for each resolution and frame rate with the High Efficiency format:

• 1080p HD at 30 fps: about 60 MB per minute
• 1080p HD at 60 fps: about 90 MB per minute
• 4K at 30 fps: about 170 MB per minute
• 4K at 60 fps: about 400 MB per minute

So ten minutes at 4K and 60 fps is roughly 4 GB. Some modes go further. Cinematic mode adds depth data, and Apple ProRes, available on some Pro models, is far heavier than the standard formats. Apple’s own settings page warns about this.

Look at your videos in Photos

Photos has no “sort by size” option. You can still narrow things down:

1. Open Photos and go to Albums.
2. Scroll to Media Types and tap Videos.
3. Scroll through and open the long ones. The duration shows in the corner of each thumbnail.

Duration is a rough guide only. A two-minute 4K 60 fps clip is bigger than a five-minute 720p one. To see the real size of one video, open it, swipe up or tap the info button, and look at the file details. That works one video at a time, which is slow with hundreds of clips.

Use iPhone Storage

Open Settings > General > iPhone Storage and wait for the bar to load. Under Photos you may see a recommendation called Review Personal Videos, which lists the videos on your iPhone. It is not shown on every device or in every state, and the list is not a ranking by size on every iOS version, so check the order before you trust it.

The same screen shows how much space Photos uses overall and whether Optimize iPhone Storage is on. Note that this setting only helps if you use iCloud Photos.

Record smaller videos from now on

Go to Settings > Camera > Formats and choose High Efficiency. It uses HEVC, which makes smaller files than Most Compatible at the same quality. Then open Record Video and pick a resolution that fits your use. 1080p at 30 fps is enough for most clips shared in a chat. Keep 4K for moments you really want to keep.

This does not shrink old videos. It only changes new recordings.

Three ways to deal with a big video

Delete it. The simplest option. If it is a duplicate, a failed take or a clip you will never watch again, delete it.

Trim it. Open the video, tap Edit, and drag the yellow handles to keep only the part you want. Tap Done, then Save Video as New Clip if you want to keep the original too, or Save Video to replace it. If you replace it, the full-length original is gone. Trimming helps with long recordings where only a few seconds matter.

Archive it first. Some videos you want to keep but do not need on the phone. Copy them to a cloud service or a computer, check that the copy plays, and only then delete the original. Never delete before you have checked the copy.

What happens after you delete

Deleted photos and videos go to Recently Deleted and stay there for 30 days. The space does not come back until they are removed from that album. Open Albums > Recently Deleted, tap Select, then Delete All, to free the space now.

iOS asks you to confirm every deletion. This is a safety feature of the system, and it applies to any app.

If you use iCloud Photos, a deletion is synced. The video disappears from your iPhone, iPad, Mac and iCloud.com. That is useful for space, but it means you cannot treat iCloud as a backup. Archive elsewhere first if you want to keep a copy.

Where Lisse helps

Lisse reads your library on the iPhone and lists every video over 50 MB, sorted from the largest. Each row shows the duration and the size, so you can see the heaviest ones in seconds instead of opening them one by one. Nothing leaves your phone and there is no account.

If you want to keep a video, Lisse can copy it to your own Google Drive first and verify each copy before you delete the original. Scanning and sorting are free, and the first 25 deletions are free. After that you need Lisse Premium: $29.99 a year with a 3-day trial, or $4.99 a week. iOS still asks you to confirm each deletion, and items still go to Recently Deleted for 30 days.

Frequently asked questions

Can I sort videos by size in the Photos app?

No. Photos sorts by date and lets you filter by media type, but it has no size sorting. You can open a video’s info to see its size, one at a time. A tool that reads file sizes, such as Lisse, can sort the whole list.

Do I get the space back right after I delete a video?

Not yet. The video moves to Recently Deleted and stays there for 30 days. Open Albums > Recently Deleted and delete the items there to free the space immediately.

Will deleting a video from my iPhone delete it from iCloud?

Yes, if iCloud Photos is on. Deletions sync across all your devices and iCloud.com. If you want to keep a copy, save it somewhere else before you delete it.
