Normally you need to have SHAREit free file transfer app installed on both devices in order to share files and documents between them. Occasionally you only have a few files, such as your photos, videos, to send to your family, friends or coworkers. And they don’t want them to download and install SHAREit for it. Is it possible? SHAREit introduced a new feature called WebShare or SHAREit for web which doesn’t require both devices to have SHAREit and it works with Wi-Fi connection.
With SHAREit WebShare, you can send files from one device to other devices, a PC, Mac or another mobile phone, with SHAREit installed on one of them only. On the other phone or computer without SHAREit, access the SHAREit WebShare address, http://pc.ushareit.com, using a web browser. SHAREit WebShare will generate a QR code.

Then use SHAREit for mobile to scan this QR code to establish connection. In SHAREit Lite for Android V3.4.29, tap on the More button to open the side menu and choose Connect to PC, then scan the QR code displayed on SHAREit web share page to connect up.

Once the phone and another phone or PC are connected, you select files in SHAREit app on the mobile and send them to other device.
On the other phone or computer, click Send button to find the files and documents to share, or simply drag files from Windows File Explorer and drop to SHAREit for Web to copy the selected files over.

Send the SHAREit app to other phones
If other people don’t have SHAREit app installed on their device, they can search and download it from Google Play or other Android market. Or you can directly share the app with them via Bluetooth or hotspot. You can find more details from this tutorial to send SHAREit app to other phone.
