Is there really no file size limit? How does this compare to WeTransfer?

Unlike WeTransfer which caps free transfers at 2GB and charges $12/month for larger files, ButterShare has zero file size limits. Files stream directly between your device and the recipient's device with 100% privacy. Because zero bytes are stored on a cloud server, you can send 10GB, 50GB, 100GB, or even larger folders without paying a dime.

Do my files ever get uploaded to your servers?

Never. There is no cloud storage, no database caching, and no file hosting. Our connection broker is only used for a split-second handshake to connect the two browsers. Once the direct connection is open, bytes stream strictly device to device. Zero bytes are ever retained anywhere.

How secure is the transfer? Can anyone intercept my files?

ButterShare uses an encrypted browser connection between the paired devices. File bytes do not sit on ButterShare cloud storage, and the room server only helps the two devices find each other.

Does the recipient need to install an app or sign up?

No. The recipient simply visits ButterShare and enters your 6-character room code (or clicks your share link). The transfer initiates immediately inside their standard web browser on any phone, tablet, or computer. No accounts, no passwords, no app installs.

Can I transfer files wirelessly between any device (Windows, Android, iPhone, Mac)?

Yes, exactly. ButterShare brings seamless, wireless device-to-device file transfer to every operating system. You can send files directly between iPhone, Android, Windows PC, Mac, and Linux with zero cables, app installs, or cloud middleman.

Can I transfer whole folders without zipping them first?

Yes. Drag and drop any folder into ButterShare. It is automatically packaged in your browser and transferred intact with its full folder directory structure preserved.

What happens if someone closes their browser tab during a transfer?

Because files stream directly between devices in real time, both browser tabs must stay open until the transfer completes. If a connection drops, ButterShare alerts you immediately with instant reconnection options. Your original files never leave your device.

Why is ButterShare completely free? What's the catch?

Because ButterShare does not host or store your files on expensive cloud servers (like AWS or Google Cloud), our operating costs are negligible. We don't have massive storage bills to pay, so we never need to charge you subscription fees or limit your file sizes.

Qué Hace ButterShare

ButterShare permite al emisor seleccionar archivos o carpetas, compartir un código de sala o enlace y mantener la pestaña del navegador abierta mientras el receptor acepta la transferencia. Los archivos se transfieren directamente entre ambos dispositivos mediante un canal cifrado.

Está optimizado para resolver los problemas de transferencia más habituales: enviar vídeos pesados en 4K, pasar archivos de iPhone a Windows sin cables, compartir carpetas sin comprimirlas en ZIP y conectar Android, Mac, Windows, Linux y Chromebook con total fluidez.
