Long videos eating your storage? Trim or compress instead of deleting
Photos get the blame, but on most phones it is video quietly eating the storage. One 4K clip can outweigh a thousand photos. And video traps you in an all-or-nothing choice: keep the whole heavy file, or delete the memory. There is a middle option. Here is how to stop videos taking up space on your iPhone without losing them.
Why videos are so heavy
Resolution and length multiply. 4K at 60 fps is gorgeous and enormous. You can shrink future clips before you even record: Settings, Camera, Formats, High Efficiency records in HEVC, roughly half the size for the same quality. That helps going forward. It does nothing for the videos already on your phone.
Trim the clip to the part you actually want
Most long videos are ten good seconds wrapped in two minutes of shoes and pavement. Gallery Checkup lets you trim frame by frame, set a start and end, and save just the good part as a new file. The original stays until you delete it, so there is no risk.
Or compress it and keep the whole thing
Want the entire video but not the size? Compress it to 1080p, 720p, or 480p. A long 4K clip dropped to 1080p can free hundreds of megabytes and still look great on a phone screen. Everything runs on the device and exports a fresh .mp4 to your library.
The videos worth the space
Some videos earn their megabytes: your pet doing something ridiculous, a place you will not see again. Keep those, and let the app pare down the rest. If a lot of your long clips are pets, TigelaBoa is a nicer home for them than a crowded camera roll, and trip footage belongs with Stamp Hunt. When you are ready for the full sweep, start with freeing up iPhone storage.
My honest take: compressing one long video is the single fastest gigabyte you will ever recover. Start there.
