Photos You Should Not Delete: A Keep List

You start a cleanup in a good mood. The first two hundred photos are easy, because most camera-roll photos are obviously disposable, and you build up a rhythm.

Then you hit a screenshot of something with a number in it. A confirmation code, maybe, or an order reference. You don’t know what it’s for anymore. You don’t know if you’ll need it. You hold your thumb over it for eight seconds, decide to deal with it later, and close the app.

That’s how cleanups die. Ambiguity is what kills them, and it happens because every cleanup guide on the internet hands you a delete list (screenshots, blurry shots, duplicates, memes, photos of food) and nothing else. You know what to throw out. Nobody has told you what to protect.

So here is the other list.

The photos you should not delete, in one list

Every item here shares a trait: it looks like junk. That’s the problem. They’re informational photos rather than sentimental ones, and a fast swipe pass kills them because they’re ugly.

Screenshots holding a confirmation, reservation, order, or reference number. The screenshot is the only copy that survives if the email gets buried or the app logs you out.
Photos of documents. Insurance card, vehicle registration, a signed form, one page of a lease, the emergency contact sheet from school.
Serial numbers, model plates, IMEI, the label on the back of an appliance. Nobody photographs these for fun. You photographed it because someone will ask.
Receipts for anything still inside a return window or warranty.
Damage. The dented bumper, the water stain spreading across the ceiling, the cracked screen, the scuffed rental car at pickup.
Prescription labels and medication bottles. Dosage, prescriber, pharmacy, refill number, all in one photo you took for a reason.
Anything you shot to remember a location. Parking level 3B, the trailhead sign, the hotel room number, where you left the bike.
Before-and-after shots taken for a landlord, contractor, or rental return. These exist to settle a future disagreement. Deleting them concedes it in advance.
The only copy of a photo someone sent you. Screenshotted out of a chat that’s since been cleared, or saved from a thread nobody backed up.

Nine categories. You can hold them in your head, which is the whole point: you’re not going to consult a list mid-swipe, you’re going to recognize the shape of a keeper as it goes past.

Screenshots are the trap

Every cleanup guide tells you to mass-delete screenshots, and for roughly nine out of ten they’re right. Screenshots are usually the largest disposable pile in a camera roll, and if you want a sense of how much room yours are eating, the screenshot storage calculator will do the arithmetic.

The other one in ten is the highest-value set of images on the phone.

The split takes about a second per screenshot. Ask one question: does it contain a number, a code, an address, or a confirmation? If yes, it’s a record. If it’s a funny post, a recipe you’ve already cooked, a meme, or a conversation you’ve long since acted on, it’s clutter.

The boarding pass nuance

Travel screenshots are where this gets misjudged in both directions.

Mobile boarding passes are increasingly dynamic. Gate and seat update live, and some carriers rotate or refresh the QR code, so a screenshot taken the night before can be stale or simply fail to scan at the gate.

Add the pass to Apple Wallet or Google Wallet as the primary, and keep the screenshot of your confirmation number or record locator as the offline fallback. The screenshot worth keeping is the one with the reference number in it, not the one with the barcode.

Receipts, warranties, and damage: the ones with a deadline

These deserve their own section because they behave differently from everything else on the keep list. They expire.

The FTC’s warranty guidance says to save your product receipt with the warranty, and it’s specific about why: the receipt proves the date you bought the product and that you’re the original owner. A manufacturer isn’t being difficult when it asks. Those two facts are the entire basis of the claim, and a photo of the receipt carries them just as well as the paper does, with the advantage that it doesn’t fade to blank in a drawer.

Insurance works the same way. The Insurance Information Institute’s home inventory guidance asks for exactly the things people already photograph without knowing why: record serial numbers, which are usually found on the back or bottom of appliances and electronics; keep proof of value in the form of sales receipts, purchase contracts and appraisals; and walk through your home on video describing the contents.

Damage photos are the other half of that, and they’re the most time-sensitive images you will ever take. A photo of the leak on the day it happened is evidence. A photo taken three weeks later, after you’ve mopped and moved things, is a picture of a stain.

A receipt photo becomes safe to delete once both the return window and the warranty have closed. Not before. And if you don’t know the warranty term, you don’t know that it’s closed, which means keep it.

The middle path: hide it instead

Cleanup guides present two options, keep or delete, which is why so many people stall. There’s a third one that almost nobody writes about: hide it.

On iPhone, Apple’s Hidden album has been locked by default behind Face ID, Touch ID or your passcode since iOS 16. Hidden items don’t appear in your Library, in other albums, or in the Photos widget, and you can set the album itself not to display at all. With iCloud Photos on, hiding syncs across your devices.

Android has the equivalent in Google Photos’ Locked Folder, a space protected by your device screen lock, whose contents don’t show up in the Photos grid as you scroll, in search, in Memories, or in albums.

This is the correct home for documents, ID-adjacent images, medical photos, and anything else you need to keep but would rather not scroll past four hundred more times. As a side effect, hidden photos also drop out of your cleanup passes, so you never have to make the same decision twice.

Hidden is not deleted, though. Those files still occupy exactly the storage they did before, so hiding buys you a tidier timeline and no gigabytes at all.

What to delete instead, and what’s risky to keep

A keep list is only useful next to its opposite. These go without a second thought:

Burst frames and near-duplicates, the eleven versions of one sunset
Blurry misfires and accidental pocket shots
Saved memes and forwarded images
Screenshots of things you already acted on
Photos of restaurant menus from restaurants you’ve already left
Long videos you watched once

If you want a sense of what that’s worth in gigabytes before you commit an afternoon to it, the camera roll cleanup estimator will give you a number, and what to delete first covers the sequencing.

Then there’s the inverse list, the photos that are an active liability sitting in an unlocked timeline:

Driver’s license, passport, or Social Security card
Someone else’s ID that you photographed to help them with something
A screenshot of a password, recovery code, or bank login
Card numbers, front or back

These are prime targets after a device compromise or an account breach, and the FTC’s identity theft guidance is a fair summary of what happens when they get out. They don’t belong on the keep list or the delete-whenever list. Move them to a Locked Folder, or off the phone entirely, today.

If you’re second-guessing a delete, the safety net is real but short, and we’ve covered how long photos stay in Recently Deleted separately.

Make the keep list before you start swiping

A keep list makes you delete faster, which sounds backwards until you’ve tried it.

Ambiguity is what actually slows a cleanup down. Every photo you can’t immediately classify costs you five to ten seconds of deliberation, and after twenty of those in a row you quit. Deciding the categories once, in advance, means most of that ambiguous pile is pre-resolved before you open the app. The swipe pass becomes mechanical, which is the only state in which anyone gets through nine thousand photos.

That’s the workflow Swipe44 is built around. Your roll gets split into decks (Recents, Random, or month by month) so you’re never staring at the whole library at once, and each photo gets one decision: swipe right to keep, left to mark. Decided photos don’t come back around, so the same ambiguous screenshot can’t ambush you three more times.

For the genuine maybes, Bookmarks is the parking spot. Marked photos collect in a pending pile you can review and rescue from before anything happens, and then the whole batch goes at once behind a single system confirmation. Duplicate grouping runs on-device with perceptual hashing, so near-identical clusters come to you instead of you hunting for them.

It can’t read your screenshots or recognize a receipt, and that’s worth being clear about. Nothing in the app knows what a serial number looks like. That’s your job, and it’s why the list at the top of this page is the actual tool here. Everything runs on-device, with no account and nothing uploaded, and iCloud-offloaded originals are never downloaded just to be shown to you. If you want it, it’s free to try.

Write the keep list down, or just remember the shape of it. Then go clear nine thousand photos without stopping once.

Frequently Asked Questions

What photos should you never delete from your phone?

Anything informational rather than sentimental: screenshots holding a confirmation or reference number, photos of documents and serial numbers, receipts still inside a warranty window, damage photos that could support an insurance claim, and prescription labels. They look like clutter, which is exactly why they get swiped away.

Should I delete screenshots of receipts?

Not while the return window or the warranty is still open. The FTC's warranty guidance is explicit that the receipt proves the date you bought the product and that you're the original owner, which is the whole reason a manufacturer asks for it. Once both windows have closed, the screenshot is clutter.

Is it safe to keep photos of my ID or passport on my phone?

That's the one category worth deleting rather than keeping. An ID image sitting in an unlocked camera roll is a ready-made identity theft kit if the device or a synced account is compromised. If you genuinely need it, move it into the Face ID locked Hidden album or Google Photos' Locked Folder instead of leaving it in the timeline.

What photos do I need for an insurance claim?

The Insurance Information Institute's home inventory guidance asks for serial numbers, sales receipts and appraisals as proof of value, and a walkthrough video of your rooms. Photos of damage (the dent, the leak, the cracked screen) are the other half, and they're worth far more taken immediately than reconstructed later.

Can I use a screenshot of my boarding pass?

Sometimes, but don't rely on it. Mobile boarding passes update live and some carriers rotate the QR code, so a screenshot taken hours earlier can be stale or fail to scan. Add the pass to Apple Wallet or Google Wallet as the primary and keep the screenshot of your confirmation number as the offline backup.

Should I hide photos instead of deleting them?

That's the right answer for anything you need but never want to scroll past. iOS moves hidden items out of the Library, other albums and the Photos widget, and locks the Hidden album behind Face ID or Touch ID by default. It doesn't free up storage. It just removes the photo from your life until you go looking for it.

How long do I have to recover a photo I deleted by mistake?

Thirty days on an iPhone or iPad, in the Recently Deleted album. Google Photos keeps backed-up items in the trash for 60 days and items that were never backed up for 30. If your iCloud storage is over quota, Apple removes deleted photos immediately with no recovery window at all.

Is it worth deleting screenshots to free up space?

Yes for most of them, since they're usually the largest disposable category in a camera roll. Just split them first: if a screenshot contains a number, a code, an address or a confirmation, it's a record rather than clutter. Everything else goes.
