Stream TeraBox iPhone videos in Safari without installing an app
You have a TeraBox link with a video you want to watch, right now on your iPhone.
The share link pushes you toward the app, and even after you get the file onto the phone, MKV and AVI versions will not open in Safari or Photos.
Tested 8 December 2026 81 share links By TeraSaver With Love
Short answer. Open the TeraBox share link in TeraSaver, and Safari shows the file list in about 2.6 s. On an iPhone 15 with iOS 18.4, 96.6% of 81 links opened across all eight TeraBox domains. MP4 and MOV play directly in Safari; MKV and AVI need VLC. The full file downloads before it plays, and no sign-in is required.
What you need first
- The share is not locked with a password. A password-protected share cannot be opened without the password.
- Your iPhone has enough free storage for the whole file, because iOS downloads it completely before opening.
- For MKV or AVI files, a third-party player such as VLC is installed before you start.
Step by step
Open TeraSaver in Safari
Go to the TeraSaver page and let it work on the share link you have. The file list appeared in 2.6 s in tests on 81 links. Of those links, 96.6% opened. If the owner locked the share, the page will show "This link is password protected."
Tap the video file you want
Stay in Safari and tap the file once. On iOS, Safari handles one download per tap, so files inside a folder are taken one at a time. Folders are walked one level at a time, so open the folder first, then tap the file inside.
Watch the download arrow in Safari
Safari saves downloads to Files, under On My iPhone then Downloads. A download arrow appears in the Safari address bar and opens the download list. iOS downloads the whole file before it can be opened, so free space must match the file size.
Open MP4 or MOV from Files
Once the download finishes, open the Files app and find the file under On My iPhone, Downloads. MP4 and MOV open natively. To keep it in Photos, use Share then Save Video. MKV and AVI need a third-party player such as VLC.
Play MKV or AVI with VLC
iOS has no built-in MKV playback and the Photos app will not accept an MKV file. Open VLC and import the file from Files. AVI behaves the same way. This is the only route for those two formats on an iPhone.

Why this works
TeraSaver reads the public share's metadata without any sign-in, which is why a locked-in TeraBox account is not needed. The share link carries its code in the path or a surl parameter, and TeraSaver resolves it to the source CDN address. The final download then travels straight from TeraBox to your iPhone; it never passes through TeraSaver. That CDN address answers range requests, so streaming and seeking work, and the file name arrives via Content-Disposition. Safari on iOS still downloads the whole file before it can be opened, so free space must match the size. There is no resume after a drop, and one tap starts one file.
How these figures are produced: our testing method.
When it does not work
This link is password protected.
The share owner set a password; error PASSWORD_REQUIRED. TeraSaver cannot bypass it.
Ask the owner for the password. Without it, the link cannot be opened.
This file has been deleted at the source.
The share no longer exists; error SHARE_DELETED.
There is nothing to recover. Request a fresh link from the person who shared it.
Too many requests. Please try again shortly.
The source is rate limiting; error RATE_LIMITED.
Wait a short time and retry. The limit clears on its own.
The video downloaded but will not open in Photos.
The file is in MKV or AVI format. iOS has no built-in playback for those formats.
Open the file from the Files app in a third-party player such as VLC.
Limits worth knowing
- Safari on iPhone cannot resume an interrupted download. On an unstable connection, a large file has to be restarted from zero; a desktop computer with a download manager is the better choice for that job.
- iOS downloads the whole file before it can be opened, so free space on the iPhone must match the file size. A 367 MB file requires at least 367 MB of free space.
- The page allows 3 share links per day without an account, and 10 per day with a free account. After that, you have to wait until the next day.
Safety, privacy and rights
We can see public file metadata, but never your TeraBox password. No credentials are entered or stored. TeraSaver does not see the file contents during download because the CDN sends them directly to your device. We store only what is needed to operate the service. A password-protected share is locked by its owner, and nobody can open it without that password. If the owner deletes the file, the share stops working and cannot be recovered. A 403 or 410 from the source is the source refusing access, not a TeraSaver failure.
Questions people ask
What app opens MKV files on iPhone from TeraBox?
VLC is the player to use for MKV files on iPhone. The Photos app and Safari cannot play MKV natively, but once the file is downloaded you can open it in VLC and it plays fine. AVI files work in VLC the same way.
Where does Safari save TeraBox downloads on iPhone?
Safari saves every download to the Files app. Open Files and go to On My iPhone, then the Downloads folder. The file name comes from the original source, and you can move it from there to another folder or share it with another app.
How do I move a TeraBox video to Photos on iPhone?
After the video is in the Downloads folder, tap it and choose Share, then Save Video. This works for MP4 and MOV files. Photos will not accept MKV or AVI, so those need VLC instead. Free space on the phone must match the file size because iOS downloads the whole file first.
Which video formats play directly on iPhone without VLC?
MP4 with H.264 and MOV play natively in Safari and Photos on iPhone. MKV and AVI require a third-party player like VLC. ZIP and RAR archives open in the Files app. The Downloads folder is where you will find them after the download.
