When it's time to send big files to a client, the reflex is to buy a cloud drive membership — yet throttled downloads still land on the client, and whether they'll install the client or log into an account is anyone's guess. Self-hosted FTP? Clients can't make sense of it, and you're on the hook for maintenance. Overseas transfer services? Access speeds from mainland China are erratic. After cycling through every tool, one truth remains: 'sending it out' is easy, but 'delivering it properly' is hard.
WringCloud puts 'delivery' first: when both sides are online, P2P direct transfer runs at full gigabit on the LAN, files never touch the cloud, and it's free with no throttling; when the other side is offline, cloud secure relay takes over — end-to-end encrypted and billed by download traffic (traffic packs from ¥1 = 2 GB) — so offline transfer works too. Delivery links carry an extraction password, expiry, download limit, and SHA256 tamper-proof checksums, with receipts and audit trails for every view and download. These are delivery-grade professional properties — exactly what cloud drive share links don't have.
Complete a delivery in three steps
Upload files, pick the transfer mode
Drag files into WringCloud and set the password, expiry, and download limit. With both sides online, P2P direct transfer engages automatically — free with no throttling; for offline delivery, cloud secure relay lets the recipient download anytime within 7 days.
Hand the link to your client
Paste it into any chat app; the client clicks and receives right in the browser — no sign-up, nothing to install, works on phones, and the recipient never pays or hands over personal information.
Close out with receipts and the Library
Views and downloads both leave receipts, so delivery status is clear at a glance; move finalized files into 'My Library' (from 50 GB on the Personal plan) for staging and archiving, ready to send with the next job.
How common transfer methods compare
For the same task — delivering a 20 GB file to a client — here's how the usual options really differ (based on each product's current behavior):
| Option | Size limit | Speed | Install / sign-up needed? | Receipts? | Positioning |
|---|---|---|---|---|---|
| Cloud drive sharing | Storage depends on your plan | Large-file downloads throttled without membership | Smoother with sign-up and the desktop client | No download receipts | Built for storage and sharing, short on delivery records |
| FTP / self-hosted server | No hard limit | Depends on server bandwidth | Needs a client and account setup | You must build your own logging | High maintenance cost; steep learning curve for clients |
| Overseas transfer service | Per-transfer limits are common | Access speeds from mainland China are unstable | Works in a browser | Notifications on some services | Subscription-based; cross-border compliance is on you |
| Chat apps, direct send | Strict size limits; large files won't send | Depends on both networks | Requires the same app | None, and files expire | Okay for daily chat; struggles with formal delivery |
| WringCloud delivery link | 10 GB per file after sign-up; unlimited via LAN direct transfer on plans | Full gigabit over P2P; end-to-end encrypted relay across networks | Opens in a browser; no sign-up | Receipts and audit trail for both views and downloads | Password + expiry + download limit, SHA256 checksum |
The above is an objective comparison of common usage patterns and is not a commentary on other products.
FAQ
How is WringCloud actually different from a cloud drive?
A cloud drive is built around 'storing'; WringCloud is built around 'delivering': delivery links carry a password, expiry, download limit, SHA256 checksum, and receipts; P2P direct transfer is free with no throttling, and cross-network secure relay is billed by download traffic (from ¥1 = 2 GB). For long-term cold backup, keep your own storage system — the WringCloud Library is for staging and archiving delivery results (from 50 GB on the Personal plan).
Can I use it for free?
Yes. P2P direct transfer between online parties is free with no throttling — up to 2 GB per file for guests and 10 GB for registered users; cross-network secure relay is billed by download traffic (traffic packs from ¥1 = 2 GB), and new sign-ups get 2 GB of relay credit free, so you can try it before deciding.
Does the recipient need to install software or sign up?
No. The link opens in a browser to receive files — phones work too. The recipient never pays and is never asked for personal information.
Does it work when the client is in another city or abroad?
Yes. It opens in a browser; when the direct connection between both networks is poor, cloud secure relay steps in — the client downloads as usual and your receipts keep coming.
The right way to judge a transfer tool is to run one transfer. Head back to the WringCloud homepage and drop in a file to try it; if you'd rather check prices first, go straight to the Plans & pricing page.
