Telegram Photos Not Opening? Fix It by Symptom
29/10/2026How to Clear Telegram Cache Without Losing Anything (iPhone, Android, Desktop)
29/10/2026How do you stop Telegram downloading files automatically?
Short answer: open Settings › Data and Storage. On Android tap When using mobile data, When connected on Wi-Fi and When roaming one by one and switch off Auto-Download Media. On iPhone open Using Cellular and Using Wi-Fi under Auto-Download Media and switch it off in each. On Telegram Desktop it is Settings › Advanced › Automatic media download.
Nothing is lost: every photo, video and file stays in the chat and downloads the moment you tap it. If you only want to save mobile data, turn it off for mobile data and leave Wi-Fi alone.
- Voice messages are fetched whenever auto-download is on at all.
- Photos have an on/off switch but no size cap on Android.
- Desktop now has per-chat Always and Never exceptions.
- Photos
- Videos up to 10 MB
- Files up to 1 MB
- Voice messages
Tap a wheel to turn it: Off, Low, Medium, High. These are the built-in fallback values in Telegram for Android; Telegram’s servers can send newer ones.
Where is the auto-download switch in each Telegram app?
Every app hides it in a slightly different place, and only the phones split it by network. Pick your app and follow the pipe from the top joint down.

- Auto-Download Mediaswitch off
Android keeps three separate screens: mobile data, Wi-Fi and roaming. Switching off one leaves the other two running. Tip: type mobile data into the search in Settings to jump straight to the screen.
What do Low, Medium and High actually download?
The Data usage slider is a shortcut that fills every switch below it at once. Moving any single switch afterwards turns the slider to Custom.
Low: photos only
- Photos in every chat type
- No videos
- No files
- No story preloading
Medium: everyday chatting
- Photos in every chat type
- Videos and GIFs up to 10 MB
- Files up to 1 MB
- Preloads larger videos, the next track and stories
High: almost everything
- Photos in every chat type
- Videos and GIFs up to 15 MB
- Files up to 3 MB
- Same preloading as Medium
Why your numbers may differ. These are the fallback values written into Telegram for Android. The app also asks Telegram’s servers for the three presets and refreshes them about once a day, so Telegram can change what Low, Medium and High mean without an app update. The labels and the logic stay the same.
Will this file download by itself?
Set up a real situation and the bench runs the same checks Telegram for Android runs before it fetches anything: network, chat type, who sent it, what kind of media and how big it is.
A 25 MB video is above the 10 MB video limit of Medium. With Preload larger videos on, Telegram fetches only the first 1 to 2 MB so playback starts instantly; the rest waits for your tap.
Rule used: size limit for videos, then preload
Why does Telegram still download things when the switches look off?
Six rules sit behind the switches, read from the Android app’s download code. Tap an inspection point on the pipeline.
Voice messages ignore the media switches
Both phone apps say it in their settings: voice messages are tiny, so they are always downloaded. In the Android code they skip the Photos, Videos and Files switches entirely. The only thing that stops them is switching off Auto-Download Media for that network completely.
- Voice messages ignore the media switches. They stop only when Auto-Download Media is off for that network.
- Photos have no size limit on Android. If Photos is on for a chat type, every photo comes in, whatever its size.
- Stickers count as photos. GIFs, video messages and game previews count as videos.
- Contacts beat chat type. In a group, media posted by someone in your contacts follows the Contacts switch.
- Preload is a partial download. Videos above your limit still fetch their first 1 to 2 MB when Preload larger videos is on.
- A tap always downloads. Auto-download only decides what happens before you touch a message.
How does auto-download work in Telegram Desktop?
Desktop has no Wi-Fi or mobile split. It has three breakers instead: one each for private chats, groups and channels, found in Settings › Advanced › Automatic media download. These are the defaults on a fresh install; flip any breaker to see what it controls.
8 of 9 breakers are on. Files in channels are the one thing Desktop never fetches by itself out of the box.
Always auto-download
Add a chat here and its photos and files come in even if the breaker for its type is off, up to the default 8 MB when no limit is set. Good for a work group whose documents you always need.
Never auto-download
Add a busy meme group here and nothing from it is fetched, while the rest keep their settings.
Each of the three windows has its own Exceptions block with Add users, Add groups or Add channels. The feature arrived in Telegram Desktop in May 2026 (beta 6.8.3) without a line in the changelog, so it is easy to miss. We found no matching per-chat download exceptions in the Android or iPhone settings.
Which settings still use data when auto-download is off?
Some data use is not called “download” anywhere in the menus. These are the drips worth checking after you close the main valve.
Autoplay Videos
Videos that start playing in the chat stream data as they play. On Android it lives in Settings › Power Usage; on iPhone in Settings › Power Saving. Telegram Desktop has its own Autoplay switches inside each auto-download window; Telegram Web keeps them in Settings › Animations and Performance.
Autoplay GIFs
Same menus as Autoplay Videos, as a separate switch. GIFs are short, but busy groups send many.
Preload larger videos
Inside the Videos settings on both phones. It fetches the first 1 to 2 MB of videos above your size limit. On Android it can only be switched on when the limit is above 2 MB.
Preload next track
Android, inside Files: starts the next audio file while you listen to the current one.
Preload Media (iPhone)
In Power Saving: “Start loading media while in the chat list for faster access.” Turn it off if you are on a small plan.
Stories
Android lists Stories as its own type next to Photos, Videos and Files. Medium and High preload them; Low does not.
What auto-download settings should you use?
Pick the situation closest to yours. The work order lists exactly what to set on each network.
Small mobile plan
- Mobile data: Data usage Low, then switch Photos off for Channels and Group Chats. Contacts and private chats keep their photos.
- Wi-Fi: leave on High so everything is ready when you get home.
- Roaming: turn Auto-Download Media off.
- Also: Autoplay Videos off in Power Usage (Android) or Power Saving (iPhone), and Preload Media off on iPhone.
Why: channels are where most unseen media comes from. You still see blurred previews and tap only what you want.
How can you measure what auto-download costs you?
Telegram counts its own traffic, so you can test any setting on your own phone instead of trusting a guess. Read the meter, change one thing, read it again a week later.
- Android: Settings › Data and Storage › Data Usage. Tabs show Mobile, Wi-Fi and Roaming separately.
- iPhone: Settings › Data and Storage › Network Usage. It splits Photos, Videos, Audio and Documents for Cellular and Wi-Fi.
- Reset the statistics, note today’s date, and use Telegram normally for seven days.
- Write the received total below. Change one setting, reset again, and compare after another seven days.
Enter both weekly totals to see the difference. Nothing is sent anywhere; the numbers stay in this page.
What else do people ask about automatic downloads?
Will I lose photos or files if I turn off auto-download?
No. Everything stays in the chat on Telegram’s servers. You see a blurred preview and the file size, and the full file downloads when you tap it.
Why does Telegram download voice messages when auto-download is off?
Voice messages are treated as tiny and are always fetched while Auto-Download Media is switched on for that network, even if Photos, Videos and Files are all off. Switch off Auto-Download Media itself to stop them.
What is the difference between auto-download and Save to Gallery?
Auto-download fetches media into Telegram’s own storage. Save to Gallery then copies finished downloads into your phone’s photo library. Turning off auto-download does not stop the gallery copy of anything you open.
Does turning off auto-download free up space?
It stops new files piling up, but it does not remove what Telegram already stored. To free space, clear the cache in Settings › Data and Storage › Storage Usage.
What does Reset Auto-Download Settings do?
It puts the three networks back to their defaults: Medium on mobile data, High on Wi-Fi and Low when roaming on Android. The button only appears once you have changed something.
Can I turn off auto-download for just one chat?
On Telegram Desktop, yes: add the chat to Never auto-download in the Exceptions block. The phone apps work by chat type (contacts, private chats, groups, channels) and we found no per-chat download exceptions in their settings. On a phone, the closest option is switching off the whole chat type that chat belongs to.
Why are videos showing a short loading bar before I tap them?
That is Preload larger videos. It fetches the first 1 to 2 MB of videos above your size limit so they start instantly. Switch it off inside the Videos settings if you want nothing fetched.
Does Telegram Web download files automatically?
Telegram Web A has its own switches in Settings › Data and Storage for photos, videos and files, per contacts, private chats, groups and channels, with a maximum file size from 1 MB to 500 MB.
Run a channel and post a lot of media?
Readers who switch auto-download off on mobile data see your caption and a blurred preview before anything else. Write captions that make sense before the media loads. If a new channel needs a first audience for those posts, these two services fit.
Which guides go well with this one?
How we checked this guide. On 26 October 2026 we read the auto-download code and settings screens of Telegram for Android (download rules, the three presets and their fallback values, the size slider and Settings search), the English settings text of Telegram for iOS, the auto-download window, defaults and change history of Telegram Desktop, the data settings of Telegram Web A, and the autoDownloadSettings object in the Telegram API. Menu names are the English ones in those apps; your app version may word them slightly differently. Written by the AddTelegramMember team, a Telegram growth service since 2019.
