How to Share Files From Phone to PC Without a Cable or Signup

2026-07-15

Short answer: Open ToolKoala's Share Files in a browser on both your phone and your PC, scan the QR code (or type the 6-digit room code) on the second device, then drag your file in. It goes straight between the two devices — no cable, no app, no account, and the file never uploads to a server.

This is the trick when you don't have the right cable, don't want to email a photo to yourself, and definitely don't want to sign up for another service just to move one file across the room.

What you need

  • A modern browser on both devices (Chrome, Safari, Edge, Firefox — anything from the last few years).
  • Both devices online at the same time. This is a live connection between the two browsers, so they both need to be awake and connected while the transfer happens.

That's it. No app from the App Store or Play Store, no login, no email.

Step by step

  1. Open the tool on device one. On the device that has the file — say your phone — go to /share-files. It shows a 6-digit room code and a QR code.
  2. Join from device two. On your PC, open the same page and either scan the QR code with the phone (or the other way around) or type the 6-digit code into the "join" box. The two browsers connect directly.
  3. Drag the file in. Once it says connected, drop your file (or pick several) on the sending device. Each file flies straight to the other device and downloads there. Big files, small files, one or many — they send one after another.
  4. Done. Close the tab when you're finished. There's nothing left on a server to delete, because nothing was ever put on one.

Why not just use a cable or email?

A cable works, but only if you have the right one and the right adapter — and lately that's a coin flip. Emailing a file to yourself works too, but now there's a copy sitting in your inbox (and on your mail provider's servers) forever, and most providers cap attachments around 25MB. Cloud upload services work, but you're back to handing your file to a company and trusting their terms. Sending the file directly between your two devices skips all of that.

FAQ

Do I need to install an app? No. It runs entirely in your browser on both devices. There's nothing to download from the App Store or Play Store, and nothing to sign up for.

Does my file go through a server? No. The file travels directly between the two browsers using a peer-to-peer connection (WebRTC). Only a tiny handshake — a few kilobytes so the two devices can find each other — passes through a coordinating worker. Your actual file never touches a server, including mine.

How big a file can I send? There's no fixed size cap, because nothing is being stored — the bytes stream directly from one device to the other. Very large files just take longer and depend on both connections staying up. For a handful of gigabytes over decent Wi-Fi, it's fine.

It won't connect — what do I do? Almost always this is a strict network blocking the direct connection (common on locked-down corporate or campus Wi-Fi). The reliable fix is to put both devices on the same Wi-Fi network, then start over to get a fresh code. Also make sure both devices are actually online at the same moment.

Can I transfer between an iPhone and an Android (or Mac and Windows)? Yes. It's browser-to-browser, so it doesn't care what the two devices are. iPhone to Windows, Android to Mac, Linux to iPad — if both can open a browser, they can send to each other. It's a cross-platform stand-in for AirDrop, which only works inside Apple's ecosystem.
