瞬传 is a free, web-based temporary file transfer tool designed for sharing files without requiring users to register. Users can send a file, set an extraction code and choose a validity period, then share the generated link with the recipient. Recipients can use the site’s pickup page to retrieve shared files, while a help section provides information about using the service.

瞬传 emphasizes short-lived transfers: once the selected period ends, the shared file is automatically destroyed, making the tool suitable for temporary handoffs rather than permanent storage. Its straightforward workflow centers on sending a file, sharing a link, and collecting the file before it expires. The site identifies the product as version 1.

0 and presents it as free to use. 瞬传 states that the tool is provided “as is” and disclaims responsibility for file loss, leakage, or transmission failures. It also asks users to comply with applicable laws and regulations and not to transmit unlawful or prohibited material
