File Transfer That Actually Works in China

The problem with sending files to China

WeTransfer is blocked

Your download link hits the Great Firewall and silently fails. Your contact never gets it. You never know.

VPNs aren't the answer

Unreliable, increasingly illegal for business use in China, and you can't ask your vendor to install one just to receive a spec sheet.

WeChat and email don't cut it

File size limits, no tracking, no branding, and files that disappear. Not a professional B2B document delivery tool.

What's blocked right now

I built Sinosend because I kept running into this problem myself working out of Hong Kong. You send a file, you hear nothing back, and you assume your contact is ignoring you. They're not - your link just silently failed at the border. The Great Firewall is not a bug or a temporary restriction. It is permanent infrastructure that blocks WeTransfer, Google Drive, Dropbox, Box, Gmail, and Slack - completely, not intermittently. OneDrive and SharePoint sometimes load, but so slowly they're effectively unusable for large files. The frustrating part is there's no error message on either end. The sender thinks the job is done. The recipient in Shenzhen or Shanghai never even saw the link. For anyone doing real business with China - sending tech packs, contracts, design files, or proposals - this is not an edge case. It happens on almost every transfer.

Where your files are stored is the whole problem

When you use a Western file transfer tool, your files sit on servers in the US or Europe. Every time a contact in China clicks download, that massive data request has to fight the Great Firewall in both directions. Sometimes it makes it; usually, it completely chokes. And you’re left guessing. The fix is simple: put the data closer to the recipient. Sinosend bypasses the firewall entirely by giving you two powerful options for your Asian trade partners. You can route transfers through our Hong Kong node (direct, fast connectivity into the mainland) or store files directly inside mainland China via our Shanghai data center, built on Alibaba Cloud infrastructure. By hosting inside the mainland, your Chinese recipients get blazing-fast local download speeds with zero firewall interference—and they don't need a VPN to access them. No matter where your business moves, we ensure your files start as close to the recipient as possible. Senders in Europe route through Frankfurt, North America uses Silicon Valley, the Middle East uses Dubai, and your China traffic lands seamlessly in Hong Kong or Shanghai.
