What It Is

极速传 is an online tool designed for temporary file transfers. Its key selling points are that it requires no registration and no app installation: just open a browser, upload files, and generate a share link or QR code. It is not a cloud drive; instead, it focuses on lightweight “short-term relay” transfers that are ready to use and easy to walk away from.

Core Features and Security

Temporary sharing from the homepage supports common file formats, with a maximum of 200MB per file and up to 20 files per transfer. You can set an access password, customize the link suffix, modify settings within the validity period, or delete files early. After a link is generated, files are physically deleted automatically after 10 minutes by default, and cannot be restored once expired. Its face-to-face direct transfer mode supports file and text transfers between two devices via a 6-digit connection code or automatic discovery under the same public IP, making it better suited for on-site use, local networks, or quick transfers between a phone and a computer.

Pricing and Collaboration

The main site does not disclose any paid plans, subscription pricing, or enterprise edition; it only mentions support via a WeChat QR code. Collaboration mainly relies on links, QR codes, passwords, and custom suffixes, making it suitable for one-off sharing. However, it does not offer enterprise-grade features such as team spaces, member permissions, audit logs, or approval workflows. On the third-party side, Cloudflare CDN acceleration is the only integration visible; no API, SDK, or business-system integration is disclosed.

Pros, Cons, and Ideal Users

Its strengths are simplicity, no login requirement, and cross-platform access. It is well suited for print shop pickup, classroom material distribution, temporary design draft delivery, test package sharing, and short-term sharing of sensitive information. The limitations are also clear: the 10-minute validity period is very short and not suitable for long-term storage; the 200MB limit and lack of resumable uploads make it unsuitable for weak networks or archiving very large files; and there is no disclosed information on enterprise security compliance certifications, SLA, or private deployment.

Access in China and Alternatives

The service uses a Chinese domain and provides QQ and WeChat support, so based on the available information, the barrier to entry for users in China appears low. However, because it relies on Cloudflare CDN, speed or availability may be affected in some network environments. If you need long-term storage and large-capacity collaboration, consider 百度网盘 or 阿里云盘. For temporary external-link sharing, you may also compare it with 奶牛快传, 文叔叔, 蓝奏云, and similar services.
