Beam: File Transfer & Share

Beam is a file transfer app for everything you own. Transfer files, photos and videos between Android, iPhone, Windows PC and Mac over the Wi-Fi you're already on. No cable, no cloud, no account, no ads.

Open Beam on both devices and they find each other. Pick what to send, tap the device, done. It's cross platform file sharing that works in every direction: Android to iPhone, iPhone to Android, phone to PC file transfer and PC to phone file transfer.

★ ANDROID, IPHONE, WINDOWS AND MAC
• Android to iPhone: share with iPhone in both directions, or share files to iPhone from any app
• File transfer to PC: Android to Windows file transfer on Windows 10 and 11. Right-click any file on the PC to send it back
• Android to Mac file transfer from Finder or the menu bar
• Or simply another Android phone. Beam is one file sender for every device in the room

★ BIG FILES, ORIGINAL QUALITY
• Large file transfer with no size limit: send big files like a 4 GB video as easily as a photo
• Transfer photos and send photos at original quality, with no compression or re-encoding
• Send videos, PDFs, documents, music and text
• Fast file transfer at the full speed of your local Wi-Fi

★ PRIVATE AND SECURE FILE TRANSFER
• Every file share is encrypted with AES-256 from one device to the other, with fresh keys each time
• Both devices prove who they are with their own keys before a byte moves
• Files go straight across your network and never touch a server
• No account, no sign-up, no tracking

★ NOTHING GETS LOST
• Each file is checked with SHA-256 before it's saved
• Wi-Fi dropped halfway? Send again and it resumes where it stopped
• Beam keeps receiving in the background, with a notification when a file lands

★ WIRELESS FILE TRANSFER, EVEN WITHOUT WI-FI
It's a wireless transfer over any shared network, and that includes a phone's hotspot. Turn one on, join it from the other device, and the wifi transfer runs with no internet needed and none of your mobile data. You can transfer files to PC, to Mac or to another phone this way.

HOW IT WORKS
1. Install Beam on both devices
2. Share any file to "Send with Beam", or pick it in the app
3. Tap the nearby device you want it on

Beam for iPhone is on the App Store, and Beam for Mac and Windows is at beam.riekapps.com.
