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.
