Some of what is in your Photos library is not really photography. It is a receipt, a chat screenshot, a screen recording of a bug, a meme someone sent you in 2024. It was useful for an afternoon. It has been taking up space ever since.
Clutter is media you made for a moment
The distinguishing feature is not size or type. It is intent. A clutter item was created to carry information from one place to another, not to be looked at later. Once the information landed, the file stopped mattering, and nothing in the system ever told you so.
That is why clutter accumulates so reliably. Real photos get reviewed, favorited, shared. Clutter is created and abandoned in the same minute.
Screenshots
The most common kind by a wide margin. Order confirmations, boarding passes, receipts, recipes, a wifi password, a map, an address someone sent you, the answer to something you have since forgotten the question to.
Individually they are small. A few thousand of them is not. They also crowd your library in a way that costs more than storage: they push actual photos out of view in the grid and into the background of every scroll.
Screen recordings are quietly the largest
A screen recording is full-resolution video at your display's frame rate, and they tend to run long because you record until the thing you were demonstrating finishes. One three-minute recording can outweigh several hundred screenshots.
They are also close to disposable. Most exist because you needed to show someone something once. If you clear one category first, make it this one.
Saved images from chats and social apps
Media saved out of messaging apps and downloaded from social apps arrives with recognizable filenames and rarely gets revisited. Some of it is genuinely worth keeping, which is why this is a review, not a purge. But a folder's worth of forwarded images is a fair thing to look at once and decide about in bulk.
How Unfill finds clutter without reading your photos
Unfill classifies clutter from two signals, both local. Screenshots are identified from the system screenshot designation that iOS itself records. Everything else is matched on filename patterns, which is how screen recordings, messaging saves, and social downloads sort into their own buckets.
No image content is analyzed for this, and nothing about it leaves the device. Filenames, thumbnails, asset identifiers, and EXIF are never sent anywhere. The optional assistant can tell you that a clutter bucket is large and offer to take you to it, working only from counts and byte totals, and it cannot delete anything.
Reviewing it without losing something you need
Work one bucket at a time, newest last. Recent screenshots are the ones most likely to still be doing a job; anything older than a few months has usually served its purpose. Before a bulk delete, scan for the two things people regret: proof of purchase, and anything with a code or a number on it.
Then remember the last step. Deleted items sit in Recently Deleted for 30 days before the space comes back, which is covered in why deleting photos does not free space immediately. If your library is mostly video rather than clutter, compressing instead of deleting is likely the bigger win.
Unfill is coming to the App Store. Questions go to support.
