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.

Does Microsoft Windows have an official AirDrop feature?

No. Apple has never released AirDrop for Windows, Android, or Linux. Microsoft offers Nearby Sharing, but it only works between Windows PCs. ButterShare delivers the closest browser-based AirDrop experience for Windows without requiring apps.

How do I AirDrop from an iPhone to Windows using ButterShare?

Open buttershare.com on your Windows PC. Open the Camera app on your iPhone and point it at the QR code on your PC screen. Tap the link to open ButterShare in Safari. Select files to send, and they will stream directly into your PC's downloads folder.

Is ButterShare better than Intel Unison or Microsoft Phone Link?

Intel Unison and Phone Link require installing software and background services on both your PC and phone. ButterShare requires zero installation on either device, works on any CPU brand (Intel, AMD, Qualcomm Snapdragon ARM), and doesn't demand account logins.

AirDrop for Windows (No App, No Cable, Free)

Why ButterShare

A Simpler, Faster Way to Transfer Files

Does Windows have AirDrop? Officially, no. Apple's AirDrop is built on a proprietary protocol (Apple Wireless Direct Link / AWDL) strictly locked to Apple hardware. Existing PC workarounds fall short: Microsoft Nearby Sharing only works between Windows PCs, Intel Unison requires specific Intel CPUs and companion apps, and Phone Link demands Microsoft account logins. ButterShare bridges this gap: open buttershare.com in Microsoft Edge or Google Chrome on Windows, scan a QR code with your iPhone or Android camera, and stream files directly with zero software installs.
