Upload

Drop files of any size. Uploads are split into chunks and sent in parallel for maximum speed.

Route

Files are automatically routed to the nearest edge server across our 46-region network.

Deliver

Share a secure link. Recipients download from the closest server, no account needed.

Read the guide How to share large files: four methods compared Share links, direct transfer, mounted drives and file requests each solve a different problem. Here is how to tell which one your situation needs. 5 min read.

Read the guide Why large uploads fail, and how resumable transfers fix it A four gigabyte upload that dies at 96 percent is not bad luck. Here is what actually breaks, and why chunked transfers make long uploads survivable. 5 min read.

Built for large file workflows

Resumable Uploads

Lost connection? Your upload picks up exactly where it left off.

Parallel Chunking

Files are split into parts and uploaded simultaneously. The part size depends on the client: the web app, REST API and SFTP gateway use 10 MB parts above 50 MB, and the native rclone backend switches to multipart above 10 MB.

End-to-End Encryption

TLS 1.2 or higher in transit, negotiating TLS 1.3 with every current client, and AES-256 at rest. Turn on the Vault and files are encrypted in your browser first, on every plan including Free.

No Egress Fees

Download and share as much as you want. No bandwidth bills.

Instant Share Links

Password-protected, expiring links. No account needed to download.

Cloud-to-Cloud

Import straight from Google Drive, or paste a link and let our servers fetch it.
