What is ButterShare?
ButterShare is a free, web-based peer-to-peer (P2P) file transfer platform engineered to solve the most frustrating bottlenecks of modern file sharing.
Most cloud-based file delivery platforms enforce restrictive ceilings. WeTransfer caps free transfers at 2GB and deletes your links after 7 days. Google Drive and Dropbox eat into your personal storage quotas and demand recurring monthly subscriptions just to hand off project files. Furthermore, traditional cloud services force your private files onto third-party datacenter disks, creating privacy vulnerabilities and forcing recipients to wait twice: once for the sender to finish uploading, and again for the recipient to download.
ButterShare replaces this outdated model with direct, real-time browser-to-browser streaming powered by encrypted WebRTC data channels.
Key Advantages:
• Unlimited File Sizes: Transfer 10GB, 50GB, 100GB, or even multi-terabyte datasets directly between devices without hitting size caps or paywalls.
• Complete End-to-End Privacy: Files are encrypted with DTLS/SRTP and stream directly from device to device. Zero bytes are stored on external cloud servers or central hard drives.
• True Cross-Platform Freedom: Send files between iPhone, Windows PC, Mac, Android, Linux, and Chromebook instantly without cables, iTunes, or installing third-party apps.
• Instant Room & QR Pairing: Generate a temporary 6-digit room code or scan a QR code with your phone camera to begin transferring immediately.
• Maximum Local Network Speeds: When both devices share the same local Wi-Fi router, transfers stream at full router throughput (up to 800+ Mbps) without consuming external internet bandwidth.
• Built-In Free Utilities: Includes bandwidth calculators, a WeTransfer limit checker, and cloud storage cost calculators to help users plan transfers and save money.
Whether you are a filmmaker sending ProRes video reels, a freelance designer delivering client assets, or simply someone wanting to AirDrop a batch of photos from an iPhone to a Windows laptop, ButterShare delivers seamless, private, and unlimited transfers right in your browser.
What problem it solves
Removes the 2GB cloud transfer limit, stops third-party cloud data harvesting, and eliminates the friction of sending files across incompatible operating systems (like iPhone to Windows PC) without installing apps.
Alternatives & competitors
We're a free, unlimited, zero-install alternative to WeTransfer, Snapdrop, Apple AirDrop, LocalSend, and Send Anywhere.
