LightDrop - QR Transfer
Send files by QR, no network
Free · In‑App Purchases
Move files between devices that share no network — one screen shows a QR code, the other device's camera reads it. No Wi-Fi, no Bluetooth, no cable, no account.
LightDrop transfers files by QR between two devices running LightDrop. One screen displays QR frames and the other device’s camera reads them. File transfer needs no shared network, Bluetooth, cable or app account.
WHEN YOU NEED IT
• An air-gapped or locked-down machine that will never join your network.
• A work computer where USB ports are disabled and cloud drives are blocked.
• Guest Wi-Fi that isolates every client, or a hotel network you would rather not trust.
• A second screen nearby when email, cloud drives, and cables are not an option.
• Anywhere a file has to cross an air gap and email is not an option.
HOW IT WORKS
• Pick text or a file on the sending device. LightDrop turns it into an animated QR stream.
• Point the receiving device's camera at that screen. Fragments land continuously and the progress grid fills in.
• Fountain coding means order does not matter and a dropped frame never restarts the transfer — keep the camera pointed and it completes.
TURBO TRANSFER (PRO)
• A binary QR fountain carries file bytes directly, without text encoding.
• Adjustable playback up to 30 frames per second. Actual speed depends on the screen and camera.
• LightDrop to LightDrop. Standard mode stays on as a compatible fallback, and the receiver recognises both automatically with nothing to configure.
PASSWORD ENCRYPTION (PRO)
• Encrypt the payload with a password before it ever reaches the screen.
• Use a strong password and share it separately; it is not included in the QR stream.
• Standard AES-GCM. Nothing leaves your device to make it work.
IMAGES, HANDLED
• Selected files are transferred as their original bytes, without automatic photo recompression.
• Preview received images. Save to Photos on iPhone and iPad, or save a file on Mac.
• Images are detected by file content, not by file extension.
LIGHTDROP PRO
Sending and receiving require LightDrop Pro, available as an in-app purchase.
GOOD TO KNOW
• Transfer speed depends on the sending screen's size and brightness, the receiving camera, and how steady you hold the device. Keep both screens clean and reasonably close.
• Large files take real time. LightDrop estimates the duration before you start, so the decision is yours.
