GigaFile Bin is a free file transfer service from GigaFile Inc., one of Japan’s most widely used platforms for sharing large files. The service is completely free for both personal and business use, with configurable retention periods and optional download passwords.

Users can upload and share files immediately without creating an account, making it easy to hand off large files in a single step. A dedicated iOS app adds background downloads, push notifications, and ZIP extraction for mobile users.

The service accepts very large files with no limit on the number of uploads, along with QR code sharing and email notifications when downloads complete.
