Find large videos in the Photos library on Mac

Why the library looks fine while storage does not

Open Photos on a Mac and the grid is organized around people, places, and days. That is useful for remembering what you shot. It is a weak way to answer a storage question. A two-hour screen recording, a burst of 4K clips from a trip, or a handful of imported movies can outweigh thousands of stills. None of that ranking is visible in Years, Albums, or Memories.

iCloud storage alerts, a disk that will not empty, and a Photos library that “does not look that big” usually share the same cause: the real byte size of videos is ignored. Thumbnails, optimized local copies, and iCloud status hide the originals that actually fill the plan you pay for.

albumlean exists for that gap. On a Mac, it lists videos in the Photos library by real file size so you can see the outliers, decide what to keep, and move the rest to Recently Deleted — locally, without using the iCloud website as a cleanup tool.

Why Photos and Finder are the wrong rulers

Finder can sort a folder of movies by size. A Photos library is not that folder. Originals live inside the library package, and iCloud Photos may keep a smaller stand-in on this Mac while the full file stays in the cloud. Browsing the package in Finder is a good way to damage the library. It is a poor way to choose what to delete.

Inside Photos you can open Info, scrub a clip, or hunt by album. You cannot say “show videos by real file size, largest first.” Optimized Storage makes the mismatch worse: a clip that looks ordinary in a thumbnail can be a multi-gigabyte original. The interface is not lying. It is answering a browsing question, not a storage question.

System Settings can report a blunt Photos library total. That number does not tell you which screen recording is 40 GB, which imported clip you already have twice, or which 4K files from three years ago are still sitting on the plan. To free space on purpose, you need a list ordered by bytes.

What albumlean actually shows

albumlean reads the Photos library you authorize on that Mac and lists videos by real file size, largest first. Each row has a size bar, so the heaviest clips are obvious before you click anything. Filename search and minimum-size filters (100 MB, 500 MB, 1 GB, 2 GB) narrow the same list when you already know the shape of the problem.

Videos whose size is unknown — typically items stored only in iCloud, with no local size on this Mac — are labeled and kept at the bottom. They are never treated as zero bytes, so they cannot hide inside a “small enough” filter. That is the difference between a real-size sort and a gallery that only knows duration or date.

The app is not a new place to browse photos. It is a manager for videos already in Photos: scan, sort, filter, preview, then ask Photos to move what you do not need. Scanning uses library metadata. It does not upload the library, create an account, or send analytics.

A short product path, not a web tutorial

Cleanup stays on the Mac you already use with Photos.

1. Download albumlean for Mac and open it. The current release is a native app for macOS 13 Ventura or later, on Apple silicon and Intel.
2. Grant Photos access when asked. The app uses PhotoKit to read video metadata from the library you authorize. It does not scan the rest of the disk.
3. Scan. Results stream in as the library is read. Videos open sorted by real size. Use date buckets or a minimum-size filter if the top of the list is still noisy.
4. Preview before you decide. Double-click to play in the app — especially screen recordings, which often look identical until you watch a few seconds.
5. Move selected videos to Recently Deleted. albumlean never deletes files itself. Photos keeps items there for about 30 days, so you have a recovery window. Emptying that album, or waiting out the window, is what returns space; if iCloud Photos is on, the change can sync to your other devices.

That path is local on purpose. You are not uploading a library to inspect it, and you are not clicking through iCloud.com to guess at file size from a thumbnail. If iCloud is already refusing new items, the same Mac-side sort is the right first move — see what to do when iCloud is full of videos.

Who this is for

People who shoot a lot of 4K, who record the screen, who import family video from phones and cameras, or who have years of iPhone clips in one library. If you are paying for a larger iCloud plan mainly because video will not fit, sorting by real size on the Mac is the practical step before you buy another tier.

It is less useful if the library is mostly stills, or if you already know the one folder of movies you want to delete and they never entered Photos. albumlean is for the case Photos owns: videos mixed into the same library that iCloud is backing up.

If the waste is not “a few huge clips” but “the same clips twice,” start with duplicate videos in Photos instead — then come back to a size sort for whatever is still heavy.
