Baidu Pan downloader services compared (September 2026): BaiduFast vs BaiduDownloader vs Erranium vs Baidu Link Downloader

Updated 13 September 2026 · 8 min read

If you search for a way to download a pan.baidu.com link without a Baidu account, you land on a handful of services that all promise the same thing. They are not the same. We checked four of them on 10 September 2026 with real links and screenshots, and put the differences in one table.

Full disclosure: we run BaiduFast. We tried to be fair, every number below is what the other sites showed or published on that day, and we name them so you can check. Prices and limits change, so treat this as a snapshot.

What each one is good at

BaiduFast (ours)

Paste the link, see the real file name, size and price in a few seconds, then decide. Under 150MB is free with no code and no sign-up, up to 3 links a day. Bigger links are $0.79 for the first GB and $0.49 for each extra GB, so a 5GB link is $2.75. Fetching runs on a premium account at a measured 15–19 MB/s, and you get a direct HTTPS link that works with IDM, aria2 or a browser. Folders come as one ZIP with the structure kept.

The limits are just as clear: Baidu Pan only. If your link is on Quark or 123Pan, we can't help yet.

BaiduDownloader (baidudownloader.com)

The closest to us in spirit: no account, you paste the link and an email. Pricing is published up front, $0.99 for the first GB and $0.50 per extra GB, so a 5GB link is $2.99 (ours is $2.75). The difference is in delivery: files go to a Google Drive folder and the link arrives by email, "usually in a few minutes to a few hours", with a note that busy periods can add up to 6 hours; the Drive link stays for 5 days. No free tier. Also handles CSDN downloads.

Baidu Erranium (baidu.erranium.com)

Also multi-platform, with a polished checkout that accepts cards through Stripe and crypto with a 15% discount, which is useful if PayPal or cards don't work in your country. A 1GB link is $2.00 and a 233MB file was quoted at $2.09, so small files are not free here. Live chat and email support.

Baidu Link Downloader (baidulinkdownloader.com)

Supports the longest list of services (Baidu, Quark, Weiyun, 123Pan, CSDN, Feimayun, Lanzou and more) and shows a Trustpilot rating on the home page. A 1GB link is $3.00, and even a 1.7MB test link was priced at $3.00, so that is the minimum order; the free option is a "Request Free" queue with an estimated wait of 6–12 hours. Best if you need a rarely supported platform and the file is worth a few dollars.

A hard link: one folder, 13,230 files

Most comparisons use an easy test file. On 13 September 2026 we tried something a real user actually sent us: a single pan.baidu.com share containing a folder of 13,230 files totalling 6.00 GB. Small files, many nested folders. Here is what each service returned for that exact link, with the extraction code supplied.

Service	Size it reported	Price it asked	What it said
BaiduFast	13,230 files, 6.00 GB (correct)	$3.24	Took 22 minutes to get there
BaiduDownloader	none	none	"Can not get link-size, please re try again"
Baidu Erranium	0 files, 0 B, order filed as 1.00 GB	$5.99	"File size unknown — the size will be assessed manually and the price may change"
Baidu Link Downloader	70.40 MB	$3.00	Queue entry read "Failed. Contact Support", yet the order was created anyway

None of the three other services could measure this folder. That is not a scandal, it is a hard link, and it is worth saying plainly that we were the slow one. But the four answers fail in very different ways, and the difference matters if it is your money.

BaiduDownloader simply declined and told us to try again. Erranium was the most transparent about not knowing: it showed zero files and zero bytes, flagged the size as unknown, and said a human would review it and the price might change. Baidu Link Downloader was the one to watch: it printed a confident 70.40 MB for a folder that holds 6.00 GB, an understatement of roughly 87 times, on a queue entry that had already reported a failure.

Where the size number comes from explains all of this. The fastest way to price a link is to read the description Baidu puts on the share page, which takes about a second. For a single file that is accurate. For a folder, Baidu's share page frequently under-reports or reports nothing at all. The slower way, which is what we do, is to copy the share into our own drive and count every file in it. That is why our number matched, and why our answer was slow.

If a quote for a folder arrives instantly, it is worth asking where the number came from. A price you can only trust after a human has re-checked it is not really a price shown before you pay.

We were slow, and we fixed it. Twenty-two minutes of a spinner is not acceptable, whatever the number at the end. Baidu's bulk listing API refuses folders with this many files, so our code fell back to walking roughly a thousand sub-folders one request at a time. Since then we show a live file count while we work, we retry the bulk listing at smaller page sizes first, and we stop after three minutes rather than leaving you waiting: past that point the link goes to our Telegram queue and a human prices it the same day.

For what it is worth, the bottleneck is the number of files, not the size. On the same day a 61 GB folder containing 202 files was priced by BaiduFast in 10 seconds. If your link is one big archive, every service here will be quick. If it is a scraped dataset with tens of thousands of small files, expect any of them to struggle, and ask a human.

Which one should you use?

• One Baidu link, under 150MB → BaiduFast, free, no account, about a minute.
• One Baidu link, 1–20GB, you want to see the price first → BaiduFast is the cheapest of the four on every size we compared (1GB: $0.79 vs $0.99, $2.00 and $3.00).
• Links from Quark, 123Pan, Alipan, Lanzou → Erranium or Baidu Link Downloader, depending on which platform they list. CSDN → BaiduDownloader or Baidu Link Downloader.
• No PayPal or card in your country → Erranium's crypto option, or message us on Telegram and we'll sort something out by hand.
• Many links or only a few files inside a huge folder → any of the four will do this manually if you ask; we do it the same day via Telegram.

FAQ

Do these services need my Baidu password? No. All four work from the public share link and the 4-character extraction code. You never give them a Baidu login.

Why do prices start around $2–3 on some sites? Payment processors charge a fixed fee per transaction, so very small orders lose money. Some sites solve that with a minimum order; we solve it with a free tier under 150MB and per-GB pricing above it.

Is it legal to use a fetch service? Downloading a file the owner shared publicly is the same as downloading it yourself. Only download content you have the right to. All four sites publish a DMCA or takedown contact.

Which is fastest? All of them use premium Baidu accounts, so the bottleneck is Baidu's own limit, roughly 15–20 MB/s per download on our measurements. Differences are in queue time, not transfer speed.

Checked on 10 September 2026, with the large-folder test added on 13 September 2026, using real links. If something here is out of date, tell us in the Telegram group and we'll fix it.
