My iPhone storage is almost full, and I found that large message attachments are taking up a lot of space. Deleting them one by one is really slow, and I need a faster way to clear large attachments on iPhone without removing important texts or photos. What’s the easiest method?
Messages still makes big attachment cleanup harder than it needs to be. I went through this mess on my iPhone, and the parts that work are oddly hidden.
Is there any quicker way than tapping files one by one?
A little. You still end up selecting stuff by hand, but one route is less annoying. Go to Settings > General > iPhone Storage > Review Large Attachments. That screen pulls the biggest files from your message threads into one list, so you are not digging through every chat.
If you want to clean one conversation only, open it, tap the contact name at the top, then check Photos or Documents. Hit See All, and you can mark multiple items from that thread in one pass.
What bugged me most, there is still no Select All option. On iOS in 2026, it feels dumb.
Does the same thing apply on iPad?
Yep. iPadOS uses the same attachment cleanup flow. The Settings path is the same, and the result is the same too. If you use Messages in iCloud, deleting something on your iPhone should sync over to the iPad. I did notice sync lag once or twice, so if it does not vanish right away, wait a bit before assuming it failed.
Does deleting attachments remove both photos and videos?
Yes. Both go away from Messages when you delete the attachment.
The part people miss is this. If you ever tapped Save Image or Save Video, your phone made a separate copy in the Photos app. Deleting the version inside Messages does not touch the saved copy in Photos. I tested this with a few clips, and the camera roll copy stayed there. If you never saved it outside the thread, then deleting it from Messages removes it for good.
Why deleted attachments show up again
I ran into two causes.
First one, Messages has its own Recently Deleted area. Deleted items sit there for 30 days. They are not gone until you clear that section. Open Messages, tap Edit in the top left of the main conversation list, then tap Show Recently Deleted. If you skip this part, the storage usually does not come back.
Second one, iCloud sync and storage optimization sometimes get weird. The phone seems to think some files still belong there and starts pulling them back in. After I emptied Recently Deleted, a restart fixed the loop and forced storage to update.
Why storage numbers stay the same after deleting stuff
Most of the time, it is still the Recently Deleted folder hanging onto the files. They keep counting against your storage for the full 30-day window unless you remove them yourself.
I also saw the storage meter lag behind. Restarting the phone after clearing Recently Deleted made the number change to something closer to reality.
When attachment cleanup is not enough
This was the part I underestimated. Message attachments were eating space, sure, but they were not the whole problem. Old screen recordings, duplicate shots, giant video files, random screenshots, all of it had piled up quietly.
If you clear Messages and ignore the rest of your library, the problem tends to come back fast.
Clever Cleaner covers the wider photo and video mess. I used it after the Messages cleanup. The Heavies tab lines files up from largest to smallest and shows exact sizes, so the worst offenders pop out fast. The Similars tab groups near-duplicate photos and picks a Best Shot, which helped with burst junk I forgot I had. It also shows file sizes before deletion. Processing stays on the device, nothing gets uploaded elsewhere.
After I cleared about 15GB with Clever Cleaner and then emptied Messages Recently Deleted, my storage finally loosened up. The slowdowns from running near full storage settled down too. Kinda annoyng it took both steps, but there it is.

Fastest route if you want bulk cleanup, delete the whole conversation with the biggest junk in it. I know, bit harsh. But if one group chat has 8GB of videos, nuking the thread takes seconds. Picking attachments one by one takes forever.
I partly disagree with @mikeappsreviewer on one thing. The iPhone Storage attachment list is useful, but it still feels slow when your problem sits in 2 or 3 massive chats. I got better results by checking which conversation was huge, saving the few photos I cared about, then deleting the thread. More storage back, less tapping.
Two other tricks people miss:
- Set Messages to keep texts for 30 Days. Settings, Apps, Messages, Keep Messages. This cuts future buildup.
- Turn off Low Quality Image Mode if you need originals, otherwise leave it on for smaller outgoing pics.
If your storage is still packed after Messages cleanup, the issue is often Photos, not Messages. Clever Cleaner helps sort giant videos, duplicates, and similar shots faster than doing it manualy in Photos.

I’d add one thing neither @mikeappsreviewer nor @byteguru really leaned on enough: if your goal is speed, stop treating Messages like a file manager. It’s bad at bulk cleanup, and Apple still hasn’t fixed that in any sane way.
What actually saves time is changing the retention settings first, then cleaning. Go to Messages settings and set Keep Messages to 30 Days if you do not need years of old threads hanging around. That won’t instantly erase everything huge, but it prevents the same storage problem from boomeranging back in a month.
Also, check whether the attachments are really in Messages only. A lot of people delete them from texts, then wonder why storage barely moved. Usually the space hog is the Photos library, not the thread itself. That’s where something like Clever Cleaner is more useful, because it can surface giant videos, duplicates, and similar shots way faster than manual scrolling. If you want a quick look at how Clever Cleaner helps free up iPhone storage fast, that explains the idea pretty well.
One small disagreement with @byteguru: deleting whole conversations is fast, sure, but it’s kinda overkill unless the thread is total garbage. I’ve regretted that before lol. Better move is save what matters first, then wipe the worst stuff.
If storage still looks stuck after cleanup, iPhone storage graphs can lag a bit. Annoying, but normal. Restart usually helps it catch up. Apple made this way more tedious than it should be tbh.
One angle missing from @byteguru, @voyageurdubois, and @mikeappsreviewer: check Messages in iCloud before you go on a delete spree. If it’s on, the same bloated attachments may be mirrored across devices, and cleanup can look inconsistent until sync finishes. Sometimes toggling Messages sync off and back on after cleanup helps the storage recalculate. I know some people hate that advice, but it has fixed “ghost storage” for me more than once.
Also, don’t ignore search inside Messages. If one person always sends giant videos, search that contact, open the shared items view, and remove batches there. It’s not perfect, but it’s faster than hopping thread to thread blindly.
On Clever Cleaner, I’d use it for the stuff Messages cleanup misses:
- Pros: fast at surfacing huge videos, duplicates, similar shots, cleaner than manual Photos cleanup
- Cons: less useful if your storage problem is only Messages, and any cleaner app still needs you to double-check before deleting
So yeah, for message junk use Apple’s built-in tools first. For the “why is my storage still full?” phase, Clever Cleaner makes more sense.
