How to clean up screenshots and large videos on iPhone
Review screenshots and videos separately. For screenshots, decide whether you still need the information. For videos, watch the content before weighing up the file size. Working through one category at a time gives each decision a little more context.
Check what each screenshot contains
Open Screenshots on PhotoSway's home screen. Directions for a finished trip or temporary information you have already used may be ready to remove. Check receipts, work records, and anything you still rely on before marking it for deletion.
Use Keep, Skip, or To delete as you review. PhotoSway uses the system's screenshot marker. Images saved again or imported without that marker may be absent from this category, so check the photo wall for anything else you want to review.
Watch large videos before deciding
Open Large videos and start with the larger files whose sizes are known. Play each video and check the beginning, middle, and end. A thumbnail can miss the part you actually want to keep. Add a video to To delete only after checking its contents.
Known sizes appear from largest to smallest. Videos with unknown sizes are ordered by duration. Duration alone does not establish file size, and an unknown size does not mean zero. Use the item's read or retry option when you need more information.
Load cloud content when you need it
PhotoSway does not download original videos during batch size checks. Explicitly reading one cloud video's original size may require a full download, so read the prompt before continuing. Playback may also need time to load from iCloud.
Apple's Optimize Storage keeps full originals in iCloud and smaller versions on your iPhone. To see your phone's current available space, check iPhone Storage in the Settings app.

Make one final review
Open To delete and check the selected screenshots and videos before completing the system deletion. Remove uncertain items from the list so you can revisit them later.
With iCloud Photos enabled, deletion syncs to your other enabled devices using the same Apple Account. Check Recently Deleted in Apple's Photos app for items that can still be recovered. Only permanently remove them there when you are certain you no longer need them.
