Frequently Asked Questions

ShareMyFile is an instant, web-based file sharing tool that allows you to send files and messages directly between devices (phones, tablets, laptops, PCs) without requiring any app installation, account, or registration.

When two devices open https://sharemyfile.link on the same local Wi-Fi or enter the same Public Room, they automatically discover each other. When you tap a device to send a file, the browsers establish a direct, encrypted WebRTC Peer-to-Peer (P2P) data channel and transfer the file directly device-to-device.

1. Open https://sharemyfile.link on both devices.
2. Ensure both devices are on the same Wi-Fi network (or join the same Public Room).
3. The other device will appear as a card on your screen.
4. Tap/click the device card to pick files to send.
5. The receiving device will see a prompt to Accept or Decline the incoming transfer.

Yes! You can send text messages, links, and notes:

• Mobile: Long-press (touch and hold) on a device card.
• Desktop: Right-click on a device card.

A message dialog will pop up where you can type your message and press Ctrl + Enter or click Send.

Never. Files are transferred directly between peer browsers using WebRTC. ShareMyFile does not even have a database or storage volume for files.

The web server only acts as a temporary "signaling" coordinator to help the two browsers find each other's IP address and shake hands. Once connected, the transfer happens purely between the two devices.

Yes. All file data sent through WebRTC data channels is encrypted in transit using DTLS (Datagram Transport Layer Security) with modern AES-128 or AES-256 ciphers. No eavesdropper on the local network or internet can inspect or intercept your files.

There is no server limit on file sizes. Because files stream directly between devices without hitting any cloud storage, you can transfer large 4K videos, full photo albums, large zip archives, and ISOs.

The only limitation is the available RAM and browser processing capacity of the sending and receiving devices.

Yes! By default, devices discover each other automatically on the same Wi-Fi. If devices are on different networks (e.g., one on 5G/LTE and one on home Wi-Fi), you can use either:

• Temporary Public Rooms: Click the Public Room icon in the top header, pick or generate a room key/link, and share the room link with the other device.
• Pair Devices: Click the Pair icon in the top header, scan the QR code or enter the 6-digit code to pair the devices permanently.

A Public Room creates a temporary virtual space for devices with the same room code (e.g. sharemyfile.link/#roomname). Devices in the room can see and transfer files to each other regardless of where they are in the world. As soon as all users close the tab, the temporary room dissolves completely.

1. Open https://sharemyfile.link in Google Chrome.
2. Click the Install button on the install banner, or tap the three dots (⋮) menu in Chrome and choose "Add to Home screen" or "Install app".
3. Confirm by clicking Add / Install. ShareMyFile will now be on your home screen and app drawer.

1. Open https://sharemyfile.link in Safari.
2. Tap the Share button (box with an upward arrow at the bottom of Safari).
3. Scroll down and tap "Add to Home Screen".
4. Tap Add in the top right corner. The app icon will appear on your home screen.

In Chrome, Edge, or Brave, look at the right end of the browser address bar (URL bar). Click the small Install ShareMyFile icon (or click the three dots → Save and share → Install ShareMyFile). It will launch in its own native standalone window.

• Ctrl + Enter: Send a message from the message dialog.
• Enter: Accept incoming file transfer request.
• Esc: Decline incoming request or close open dialogs.
• Ctrl + C: Copy received text message to clipboard.

If two devices on the same Wi-Fi don't see each other, check the following:

• AP / Client Isolation: Some public or office Wi-Fi routers prevent devices from talking to each other directly for security. In this case, use a Public Room or connect one phone to the other via Mobile Hotspot.
• VPNs: If one device has a VPN turned on, its public IP changes, making the server think it is on a different network. Turn off the VPN or use a Public Room.
• Browser Permissions: Ensure WebRTC is not blocked by third-party browser privacy extensions.
