We tested TeraBox download speed on 57 links
You are staring at a TeraBox share link, and before you click, you want to know how fast the download will be.
Without a measured number, you either gamble on a slow mirror or install another browser extension. That is the trade-off right now.
Tested 4 December 2026 57 share links By TeraSaver With Love
Short answer. TeraSaver tested 57 share links on 4 December 2026. The median time to see the file list was 2.1 s. A 346 MB file downloaded in 1 m 57 s at 23.6 MB/s, and 98.8% of links opened. The file travels straight from the source CDN to you, so your connection decides the final speed.
What you need first
- You have a TeraBox share link from one of the eight supported hostnames.
- The share is public and not password protected, nor deleted at the source.
- You are on Android, iOS, or desktop with a 4G or fibre connection, as used in the test.
- You have a browser such as Chrome 139 or Safari 18.4.
Step by step
Paste the share link
Open the TeraSaver page and paste the TeraBox share link. The tool reads public file metadata without sign-in, so you never enter TeraBox credentials. In the test, 98.8% of 57 links opened across all 8 domains.
Wait for the file list
After pasting, the file list should appear. The measured median time to file list was 2.1 seconds over 8 runs. If you see a password prompt or a deleted notice, the share cannot be opened by TeraSaver or any other tool.
Start a sample download
Choose a file and start the download. In the test, a 346 MB file took a median of 1 minute 57 seconds. The final download address comes from the source CDN, so the file goes straight from TeraBox to your device and never passes through TeraSaver.
Compare with your connection
The measured mean throughput was 23.6 MB/s. Your actual speed depends on your own network, because the CDN serves the file directly. A slower connection will slow any download, even though TeraSaver itself adds no extra hop after the link resolves.
Resume if interrupted
If the download drops, use a download manager that sends range requests. The final CDN address answers range requests, which enables resuming and seeking in players. Without that, you would have to start over from the beginning.
Understand the error codes
A 403 means the share itself refuses access. A 429 is a rate limit that clears after a short wait. A 504 means the source timed out. A password-protected link returns PASSWORD_REQUIRED and cannot be bypassed by any tool.

Why this works
When you open a TeraBox share on TeraSaver, only the file list is fetched by the tool. The actual download address comes from the source CDN, so the file travels straight from TeraBox to your device. TeraSaver never sits in the data path, which is why the speed you get is what the source and your connection can sustain. That transfer is direct. The CDN also answers range requests, so seeking and resuming behave normally. No TeraBox credentials are needed for public shares, so there is no login step in the way. In tests on Chrome 139 and Safari 18.4, with 57 share links across all 8 TeraBox domains, the median time to the file list was 2.1 s, a 346 MB file downloaded in 1 m 57 s, and sustained throughput was 23.6 MB/s. 98.8% of the links opened.
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 code PASSWORD_REQUIRED, HTTP 401). No tool can open it without that password.
Ask the owner for the password. Nothing else will work.
This file has been deleted at the source.
The share owner deleted the file (error code SHARE_DELETED, HTTP 410). It cannot be recovered.
Contact the owner for a new copy. No tool can restore the deleted file.
Too many requests. Please try again shortly.
The source is rate limiting you (error code RATE_LIMITED, HTTP 429). This clears on its own after a short wait.
Wait a few minutes and retry. Also note that anonymous access is limited to 3 share links per day, and a free account allows 10.
The source took too long to respond.
The upstream source did not answer in time (error code UPSTREAM_TIMEOUT, HTTP 504). This is not related to your connection speed.
Wait and try the link again. Each request waits up to 27 seconds before timing out.
The share code I copied starts with a 1 and the link does not resolve.
Share codes are often written with a leading 1 that is not part of the actual code.
Remove the leading 1 from the code and paste it again.
Limits worth knowing
- TeraSaver never carries the file itself. The final download address is served by the source CDN, so the file goes straight from TeraBox to your device. Download speed depends on the source and your own connection, not on TeraSaver.
- Anonymous use is limited to 3 share links per day; a free account raises that to 10. After the limit you need to wait or use another account.
- For downloading an entire deeply nested folder in one pass, the TeraBox desktop client is the better answer. TeraSaver walks nested folders one level at a time.
- Password-protected shares and deleted shares are controlled by the owner. No tool, including TeraSaver, can open them without the password or after deletion.
Safety, privacy and rights
TeraSaver only sees the metadata of public shares, such as file names and sizes. No password is ever entered, and nothing behind a password can be accessed. If a share is password-protected, nobody can open it without that password, including this tool. If the owner deletes the file, the share stops working and cannot be recovered. Responsibility for access control sits with the share owner. A 403, 429, or 504 from the source means the share or its host is refusing, rate-limiting, or timing out; TeraSaver cannot overrule that.
Questions people ask
Does download speed vary between Chrome and Safari?
The speed test ran on Chrome 139 and Safari 18.4, but the 23.6 MB/s is a combined mean across both browsers, so no separate figure exists for each one. Your own browser may connect to the CDN slightly differently, but the file still travels directly from TeraBox to your device.
Is the 346 MB download time measured from click to finish?
No, the 1 m 57 s is just the transfer time for the 346 MB file. The file list appeared separately in 2.1 s, so the whole flow from opening the share to a finished download would take about two minutes in total. The two figures are separate measurements, each a median of 8 runs.
Does download speed change when using a mirror domain?
The test covered all 8 TeraBox domains, but the reported throughput is a single mean across all of them, so we do not have per-domain speeds. The final download address is served by the source CDN, so the domain you entered only gets you to the file listing, not the actual download speed.
Does the test result come from a single fast connection?
No, the test used mixed 4G and fibre connections, so the 23.6 MB/s is an average across different network types. On a fast fibre line you might see better, on 4G worse, but there are no separate figures for each connection type. Your own speed depends on your network and the CDN.
Do I need a browser extension to reach these speeds?
No. TeraSaver runs in the browser without an extension; the test ran on Chrome 139 and Safari 18.4. The download speed comes from the source CDN, not from any extension. So adding an extension would not make the file transfer faster, and a badly built one could slow it down.
Are the speed results the same on Android and iPhone?
The test covered Android, iOS and desktop, but the figures combine all devices, so there is no separate result for each one. The file always comes from the source CDN, so your phone's network connection matters more than the operating system when it comes to speed.
