How to find large videos
on iPhone.

See every video in Photos

1. Open Photos and find Media Types: on iOS 26 or later tap Collections, then scroll down; on iOS 18 scroll down.
2. Tap Videos.
3. Open a video and swipe up, or tap the Info button, to see its file size.

Why Photos can't sort videos by size

Photos sorts by date only: by when an item was captured or added in the library, and newest first, oldest first or a custom order in an album. There is no size order, so finding the heaviest videos means opening them one at a time.

The review list in Settings

1. Open Settings › General › iPhone Storage and wait for the list to load.
2. Tap Photos.
3. On iOS 26 or later, tap Review Photos & Videos, then Videos. On iOS 18, look for a similar review option on the same screen.

This list covers the videos iOS suggests reviewing, and iOS only offers it when it has something to suggest.

List videos largest first, then compress them

Phone Cleaner's Videos category on the Clean tab opens with the largest file first and shows the size of each one. From there you pick the videos to compress at one of three levels (Low, Medium or High), with Keep originals on if you want to compare first.

Step 1 of 6On the Clean tab, the Videos card shows what your videos take: 27.4 GB. Tap it.

Step 2 of 6Videos opens largest first, each with its size: 8.4 GB, 6.2 GB, 5.1 GB. Tap the ones to shrink.

Step 3 of 6Three picked, 19.7 GB in all: compressing them saves about 9.85 GB. Tap Compress Selected.

Step 4 of 6Pick a level: Medium takes them from 19.7 GB to about 9.85 GB. To compare first, turn on Keep originals; here it stays off, so each original is replaced. Tap Compress 3 videos.

Step 5 of 6It compresses on your iPhone. Nothing is replaced until every video is ready; then iOS asks you to confirm once.

Step 6 of 63 videos compressed: the library is 9.85 GB smaller. The originals wait in Recently Deleted, and the space comes back when you empty it, or after 30 days.
