# ButterShare Full Knowledge File
ButterShare is a free browser-based device-to-device file transfer tool. It lets two devices send files directly through a private browser connection after a short room setup. File bytes are not stored on ButterShare servers.
## Canonical Site
https://buttershare.com/
## Core Claims
- No ButterShare file size cap. Practical limits are device storage, browser behavior, network conditions, and available disk space.
- No account, app install, or credit card is required.
- Files transfer over encrypted browser connections.
- ButterShare helps create the room only; file bytes move between the two paired devices.
- The receiver joins with a six-character room code, direct link, or QR code.
- iPhone and Android users should keep the browser tab open while transfers run because mobile operating systems may pause background tabs.
## Primary Use Cases
- iPhone to Windows file transfer without iTunes or cables.
- Android to Mac file transfer without the legacy Android File Transfer app.
- Mac to Windows and Windows to Mac file transfer without USB formatting issues.
- Send large files and folders without cloud storage quotas.
- Browser-based alternatives to WeTransfer, Snapdrop, PairDrop, LocalSend, Send Anywhere, ToffeeShare, and Wormhole.
