## What it is
Transfer.zip is an open-source, self-hostable file-sharing service and website, an alternative to WeTransfer, with stored transfers (S3 or disk) and end-to-end encrypted peer-to-peer 'Quick Transfers' via WebRTC. It uses the tus protocol for reliable uploads and supports email delivery, transfer request links, and custom branding.

## Use cases
- send large files to clients without size limits
- self-host a WeTransfer alternative
- transfer files peer-to-peer in the browser with end-to-end encryption
- create upload links so others can send files to me
- send files to multiple email recipients
- share files with custom branding on a download page

## When to choose
- you want a self-hosted, open-source file transfer service with encryption
- you need reliable resumable uploads of very large files
- you want branded download pages and email delivery for clients

## When to avoid
- you only need simple one-off anonymous file drops without hosting anything
- you need a managed service and don't want to run your own infrastructure
- your network blocks WebRTC peer-to-peer connections for quick transfers
