How to Find and Delete Large Videos on iPhone
Videos take far more iPhone space than photos. Learn how to find the biggest ones, decide what to keep, and free up gigabytes without regret.
Why large videos are the fastest way to free up iPhone space
A single minute of 4K video can take hundreds of megabytes, while a typical photo takes a few. That means ten forgotten clips can take up more room than a thousand photos. If your storage is full and you want the biggest win for the least effort, start with videos.
The catch is that videos are harder to judge than photos. You can't tell at a glance whether a 6-minute clip is a keeper, and nobody wants to sit through old footage to decide. The rest of this guide shows how to find the heavy hitters and make quick decisions about them.
How to find big videos with the built-in Photos app
Open Photos, go to Albums, and scroll to Media Types. The Videos album collects every clip, and each thumbnail shows its duration in the corner. Long duration is a decent proxy for large file size. Slo-mo, Cinematic, and Screen Recordings have their own albums and are worth a look too.
Apple doesn't offer a sort-by-size option, so you have to work around it. Scan for thumbnails with long durations, then open one and view its info panel, which on recent versions of iOS includes the file size. Check Settings, General, iPhone Storage as well to see how much space Photos is using overall.
Deciding what to keep without watching everything
A few quick questions settle most clips. Is it a one-off moment you'd regret losing, like a first steps clip or a concert snippet? Or is it a failed take, an accidental recording, or a screen recording you made for a one-time purpose? Be ruthless with the second group and generous with the first.
For clips that are worth keeping but too long, trim them. In Photos, open the video, tap Edit, and drag the yellow handles to keep only the good part. Save it and delete the original, and you keep the memory at a fraction of the size.
Remember that deleted videos sit in Recently Deleted for about 30 days. Your storage won't recover until you empty that album or the time runs out, so check it if the numbers don't change right away.
Stop the buildup: camera settings that shrink new videos
Go to Settings, Camera, Record Video to see the resolution and frame rate you're using. 4K at 60 fps looks superb, but it takes roughly twice the space per minute of 4K at 30 fps, and several times more than 1080p. For everyday clips, a lower setting is often indistinguishable on a phone screen.
Also check Settings, Camera, Formats and choose High Efficiency. It uses the HEVC format, which stores video in noticeably less space than the most compatible option. Save the highest settings for moments that really deserve them.
Where Phlash fits in
Phlash has a large-video cleanup mode that surfaces your biggest clips so you aren't hunting through albums. You swipe to keep, delete, or skip, one video at a time, in a short session. Skip is useful here, since some videos need a second look before you decide.
Everything is processed on your device, so your videos aren't uploaded anywhere for analysis. A delete safety net also gives you a chance to catch a mistake before anything is gone for good.
Clear out your heaviest videos in one short session
You don't need a weekend project to reclaim space. Ten minutes on your largest videos can free up more storage than an hour of deleting photos one by one.
If you'd like a calmer way to do it, try Phlash, the Photo Cleaner from Culi, on the App Store. Start with large videos, swipe through a handful, and see how much room you get back.
