What Is the Fastest Way to Transfer Large Files Between Devices?

We tested USB drives, cloud storage, Bluetooth, and local Wi-Fi P2P. Here are the definitive speed test results.

When you need to move a 5 GB file right now, every minute counts. Should you hunt down a USB drive? Upload it to Google Drive? Or use local Wi-Fi? We put every method to the test.

💡 Real-Life Comparison:

Bluetooth is a bicycle, Cloud storage is a cargo ship traveling around the globe, and Local Wi-Fi P2P is a supersonic jet flying straight to your target.

Why Does This Usually Feel So Annoying?

Cloud services waste time by forcing you to upload to a remote server and then download back down, doubling the total transfer duration.

How to Do It in 3 Easy Steps (No Cables, No Apps!)

Think of iFileSender Fast Transfer like a super-fast invisible slide between your two devices. Here is all you have to do:

Step 1: Open iFileSender and Pair Up

On Device #1 (like your Mac or iPhone), open your browser and go to iFileSender. You will see a friendly 6-digit pairing code and a QR code on your screen.

Now grab Device #2. Open the browser or camera, point it at the QR code, or simply type in the 6-digit code. In less than a second, both devices give each other a high-five and pair up directly!

Step 2: Pick Your Files from Either Side

Because iFileSender works both ways (two-way street!), you can send files from either device. Tap or click Select Files or simply drag and drop your photos, videos, or documents onto the screen.

Step 3: Zoom! Direct Local Wi-Fi Transfer

Hit transfer! Your files fly directly across your local Wi-Fi router from one device to the other. There is no server in the middle, no waiting for slow cloud uploads, and no compression. When it finishes, tap Save and your files are right in your downloads or gallery!
