How do I find which videos are taking up the most space on my iPhone?

Go to Settings > General > iPhone Storage and tap Photos — iOS shows an estimate of how much space your library uses, though it doesn't break videos out individually. Inside the Photos app, sorting your camera roll by file size (available in apps like Odoa) is the fastest way to see which specific videos are the biggest offenders.

Why do iPhone videos take up so much storage?

A single minute of 4K video can be 300–400 MB, several times larger than a photo. Slow-motion and longer clips multiply that further. A handful of videos can easily outweigh hundreds of photos combined.

Does lowering video quality free up storage on old videos?

No — changing your camera's recording settings only affects videos you record after the change. Videos already saved stay at their original size and resolution until you delete or manually compress them.

Is it safe to delete videos from my iPhone?

Yes, as long as you review each one before deleting — some videos are much easier to lose accidentally than you'd expect, since they don't always play automatically while scrolling. Deleted videos go to Recently Deleted for up to 30 days, so there's a safety net if you change your mind.

How to Delete Videos Taking Up Space on iPhone

Videos are usually the single biggest reason an iPhone camera roll takes up so much storage — a handful of clips can outweigh a thousand photos. Here’s how to delete videos that are taking up space without losing the ones worth keeping.

Find your biggest videos first

The fastest way to reclaim space is to go after your largest videos first, not your oldest ones. A single long or 4K clip can be worth hundreds of photos, so a few smart deletions go a lot further than scrolling chronologically.

Go to Settings > General > iPhone Storage to see how much space Photos is using overall. From there, sorting your camera roll by file size — which apps like Odoa support — surfaces the heaviest videos immediately instead of making you guess.

Why videos eat storage so much faster than photos

Resolution: a minute of 4K video can be 300–400 MB, versus a few megabytes for a photo.
Slow motion: recorded at a much higher frame rate, so the same few seconds take up far more space.
Duration creep: it’s easy to record 45 seconds of something that only needed 5.
Live Photos: every Live Photo includes a short video clip attached to it, adding up quietly across thousands of photos.

What’s actually worth keeping

Not every video deserves a spot on your phone forever. Before deleting, sort mentally into three groups:

Keep: the ones you’d actually rewatch — a moment, an event, someone’s voice.
Trim mentally, keep the best seconds: long recordings where only a short clip matters. You can’t easily trim and keep just that clip on-device, but you can decide the whole video isn’t worth the space.
Delete: accidental recordings, duplicate takes of the same moment, and clips you took “just in case” and never opened again.

Step by step: clear video clutter fast

1. Sort by size, not by date

Your five largest videos are often worth more storage than a hundred of your oldest photos combined. Clearing those first gives you the biggest win for the least effort.

2. Check Live Photos too

Live Photos carry a hidden video cost. If you don’t need the motion effect on old shots, they’re worth reviewing alongside your regular videos — see how to clean up your iPhone camera roll for a full pass that includes them.

3. Watch for duplicate takes

Recording the same moment two or three times “to be safe” is common and rarely necessary in hindsight. Treat duplicate video takes the same way you’d treat duplicate photos — keep the best one, delete the rest.

4. Empty Recently Deleted

Deleted videos sit in Photos > Albums > Recently Deleted for up to 30 days and still count against your storage until you empty it. For large videos, this step alone can free multiple gigabytes instantly.

A lighter way to record going forward

You can’t shrink videos already on your phone by changing settings, but you can slow the problem down: in Settings > Camera > Record Video, choosing a lower resolution for everyday clips (saving 4K for moments that need it) keeps future videos smaller by default.

The bottom line

Videos are almost always the fastest place to recover real storage, because a few large clips can outweigh hundreds of photos. Sort by size, review your Live Photos and duplicate takes, empty Recently Deleted, and you’ll likely free several gigabytes in one short session.
