To delete large videos on iPhone, open Settings › General › iPhone Storage, tap Review Large Attachments (or open the Photos and Videos breakdown), then delete the heaviest clips first to reclaim several gigabytes fast. A single 4K or ProRes recording can be larger than hundreds of photos, so clearing a few big videos is the quickest way to free space.
TL;DR
- The fastest path: Settings › General › iPhone Storage › Review Large Attachments lists your biggest files by size.
- 4K and ProRes clips are storage hogs — a few can free more space than thousands of photos.
- Deleted videos go to Recently Deleted for 30 days, so they're recoverable.
- Back up keepers to iCloud, Google Photos, or a computer before deleting.
- A cleaner app can sort your whole library by size in one tap for faster review.
Why do videos take up so much space on iPhone?
Videos are by far the largest files most iPhones store. A minute of 4K video at 60 fps uses roughly 400 MB; ProRes on Pro models can hit several gigabytes per minute. Because each frame is a full image, a short clip can outweigh an entire photo album. That's why videos take so much space on iPhone and why deleting a handful of the biggest ones is the single most effective storage cleanup. The trick is finding them — iOS doesn't sort your camera roll by file size by default.
How do I find the largest videos on iPhone?
Apple gives you two built-in ways to surface big videos. Here are the exact paths:
Method 1 — Review Large Attachments (fastest)
- Open Settings › General › iPhone Storage.
- Scroll down and tap Review Large Attachments.
- iOS lists files sorted largest-first, including videos sent in Messages.
- Swipe left on any item to delete it.
Method 2 — Photos app
- Open Photos › Albums › Media Types › Videos.
- Tap the longest clips (length roughly tracks size).
- Select and delete the ones you no longer need.
For a true size-sorted view of your entire library, a cleaner app is faster — it ranks every clip by gigabytes so you can clear the worst offenders first.
How to delete large videos step by step
- Back up videos you want to keep to iCloud, Google Photos, or your computer first.
- Open Settings › General › iPhone Storage › Review Large Attachments.
- Tap Edit, select the biggest clips, and tap the trash icon — or swipe left to delete individually.
- To free the space immediately, go to Photos › Albums › Recently Deleted, then Select › Delete All.
- Reopen iPhone Storage to confirm the gigabytes were reclaimed.
Built-in tools vs. a cleaner app for large videos
| Factor | Settings / Photos | Cleaner app |
|---|---|---|
| Sorts by exact file size | Partly (Large Attachments) | Yes, whole library |
| Shows GB per clip | Limited | Yes |
| Batch-delete biggest first | Manual | One-tap selection |
| Catches duplicate videos | No | Yes |
| Cost | Free, built in | Free or paid |
The built-in tools are enough for an occasional cleanout. If you record a lot or want to clear duplicate videos at the same time, an app that ranks clips by size saves real time.
Is it safe to delete large videos from iPhone?
Yes, as long as you've backed up anything irreplaceable. Deleted videos move to Photos › Albums › Recently Deleted and stay there for 30 days, so an accidental deletion is recoverable during that window. The permanent step is emptying Recently Deleted. If your videos sync to iCloud Photos, deleting one on your iPhone removes it from iCloud too — so confirm you have a separate copy if a clip matters. Deleting large videos never touches apps, messages, or photos you keep; it only removes the specific files you select.
FAQ
Where are the largest videos stored on my iPhone?
They live in your camera roll and in Messages attachments. The quickest way to surface them is Settings › General › iPhone Storage › Review Large Attachments, which lists files largest-first.
How much space can deleting large videos free?
A lot — a single minute of 4K/60 video is about 400 MB, and ProRes clips can be several GB per minute. Removing a few long recordings often frees more space than deleting thousands of photos.
Can I recover a large video after deleting it?
Yes, within 30 days. Deleted videos go to Photos › Albums › Recently Deleted, where you can restore them until that window closes or you delete them manually.
How do I delete large videos but keep a copy?
Back them up to iCloud, Google Photos, or your computer first, then delete from the phone. See how to share large videos without killing your own storage.
Why is my iPhone still full after deleting videos?
The space isn't reclaimed until you empty Recently Deleted. If it's still full, check why your iPhone storage stays full even after deleting.
Free up gigabytes the fast way
Large videos are usually the biggest single win when storage runs out — but duplicate videos and oversized clips piling up before a recording add up too. For the full playbook, see the clean up phone storage solutions hub. To rank every clip by size and review duplicates locally before deleting, Cleanor for iPhone does it in one scan with nothing uploaded.
