## Features
[PairDrop](https://pairdrop.net) is a sublime alternative to AirDrop that works on all platforms.
Send images, documents or text via peer to peer connection to devices in the same local network/Wi-Fi or to paired devices.
As it is web based, it runs on all devices.
You want to quickly send a file from your phone to your laptop?
You want to share photos in original quality with friends that use a mixture of Android and iOS?
You want to share private files peer to peer between Linux systems?
AirDrop is unreliable again?
_Send it with PairDrop!_
Developed based on [Snapdrop](https://github.com/RobinLinus/snapdrop)
## Differences to Snapdrop
### Device Pairing / Internet Transfer
* Pair devices via 6-digit code or QR-Code
* Pair devices outside your local network or in complex network environment (public Wi-Fi, company network, Apple Private Relay, VPN etc.).
* Connect to devices on your mobile hotspot.
* Paired devices will always find each other via shared secrets even after reopening the browser or the Progressive Web App
* You will always discover devices on your local network. Paired devices are shown additionally.
* Paired devices outside your local network that are behind a NAT are connected automatically via the PairDrop TURN server.
### [Improved UI for sending/receiving files](https://github.com/RobinLinus/snapdrop/issues/560)
* Files are transferred only after a request is accepted first. On transfer completion files are downloaded automatically if possible.
* Multiple files are downloaded as a ZIP file
* On iOS and Android, in addition to downloading, files can be shared or saved to the gallery via the Share menu.
* Multiple files are transferred at once with an overall progress indicator
### Send Files or Text Directly From Share Menu, Context Menu or CLI
* [Send files directly from context menu on Windows](/docs/how-to.md#send-files-directly-from-context-menu-on-windows)
* [Send directly from share menu on iOS](/docs/how-to.md#send-directly-from-share-menu-on-ios)
* [Send directly from share menu on Android](/docs/how-to.md#send-directly-from-share-menu-on-android)
* [Send directly via command-line interface](/docs/how-to.md#send-directly-via-command-line-interface)
