How to Use Bluetooth to Transfer Files Between Devices

Send data, music, and photos without an internet connection

What to Know

  • Android: Open the file manager and select files. Choose Share > Bluetooth. Then select a device.
  • macOS or iOS: Open Finder or the Files app >locate the file > Share > AirDrop. Follow on-screen instructions.
  • Windows: Open the file manager, right-click the file > Send to > Bluetooth device. Then select a device.

This article explains how to use Bluetooth to wirelessly transfer files like photos to and from your mobile devices without incurring data charges.

To set up a Bluetooth file transfer between smartphones, tablets, and PCs, enable Bluetooth (and visibility). You can set up (or pair) the mobile device with a desktop or laptop.

Send Files from Smartphones and Tablets

To transfer files from a smartphone or tablet to a PC:

  1. Open the File Manager app. This also could be called Explorer, Files, File Explorer, My Files, or something similar. On Android Marshmallow or later, open the Settings app to find the file manager.

    If your device doesn't have a file manager app, download one from the Google Play store.

    While iOS has a Files app, it doesn't generally allow Bluetooth transfers. Instead, it uses AirDrop for non-internet file transfers, which uses Bluetooth and Wi-Fi.

  2. Go to the folder that contains the files you want to transfer. Camera photos are usually found in the DCIM folder.

  3. Tap the Menu icon and choose Select.

  4. Select the files you want to send.

  5. Tap the Share icon.

  6. In the list of sharing options, tap Bluetooth.

    If the devices haven't been paired, it may take a few seconds to discover the receiving device.

  7. Tap the Bluetooth device you want to transfer the files to. A message that displays "Sending # Files to [device]" appears on the screen.

  8. A file transfer notification appears on the receiving device that shows the file name, file size, and the sending device. This window may disappear (nothing will be transferred) if no action is taken within 15 seconds. If this happens, send the files again.

  9. Select Accept on the receiving device to download the files. If the receiving device is a computer, choose a folder location. If you want to cancel the transfer, select Decline, Cancel, or Reject, depending on your PC.

Send Files from Computers

While macOS supports Bluetooth, file transfers with that system are managed by AirDrop. Windows PCs are able to send files to a mobile device (and vice versa).

  1. Open a file manager (on Windows, open File Explorer) and go to the folder that contains the file you want to send.

  2. Right-click the file.

    Only one file at a time can be transferred over Bluetooth.

  3. Select Send To and choose Bluetooth.

  7. Select Finish when the file transfer is complete.

What Is Bluetooth File Transfer?

Bluetooth file transfer is a simple way to send files to another nearby Bluetooth device without the need for a separate app. Bluetooth is compatible with smartphones, tablets, laptops, and desktop computers. You can transfer files over Bluetooth using Android OS, Fire OS, Windows OS, Mac OS, and Linux OS.

Bluetooth file transfer isn't supported between iOS and Chrome OS. On iOS, you need to use a separate app such as Move to iOS or Apple AirDrop to transfer files and photos from the iPhone to Android or Chrome OS over Bluetooth. Devices that are compatible with Bluetooth file transfer have a system setting that supports Bluetooth and is called Bluetooth Share (or something similar).

Chrome OS 89 adds a feature called Nearby Share, which lets you move files between your Chromebook and other Chrome OS or Android devices instantly and securely.

Why Use Bluetooth File Transfer?

There are several ways to transfer files from smartphone to smartphone, Android to Android, or from one OS platform to another. Bluetooth isn't the fastest method, but it has the fewest requirements—no app, no cable or hardware, no Wi-Fi network, and no data connection.

When you want to share photos between smartphones, here are the advantages of using Bluetooth:

  • Bluetooth vs. USB Cable: If you don't have the USB charging cable for your device, turn on Bluetooth to transfer files. If you do have the USB cable, it may be the type that plugs into a standard USB port instead of into another mobile device.
  • Bluetooth vs. OTG Cable: OTG cables will transfer files between devices, but both devices must support USB OTG and have the right connections for the cables.
  • Bluetooth vs. OTG Flash Drive: There are flash drives that have dual connectors for use with computers, smartphones, and tablets. While more convenient than OTG cable, OTG, and connector compatibility between devices is required.
  • Bluetooth vs. Personal Hotspot: Not all devices use a personal hotspot (tethering). A personal hotspot requires a fee and a strong signal.
  • Bluetooth vs. Portable Media Hub/Hard Drive: Some portable media hubs and hard drives broadcast their own local wireless network for devices to connect to. The mobile device needs the companion app to transfer files and the drive needs its battery charged.
  • Bluetooth vs. Wi-Fi Direct: Transferring files over Wi-Fi direct is similar to transferring files over Bluetooth. But Wi-Fi direct isn’t as universal as Bluetooth, not many devices support the feature, and may require an app to use it.
  • Bluetooth vs. Cloud Storage/Email: Cloud storage and email work well for saving and sending files. However, each device needs a strong data or internet connection to transfer files or access email.
  • Bluetooth vs. File Transfer App: The Google Play Store and the Apple App Store have apps that transfer files from one device to another. Some of these apps only work when both devices have the same app and some may need a wireless or data connection.

Types of Transferrable Files

Most any type of file can be transferred over Bluetooth: documents, photos, videos, music, apps, and more. If a file is stored in a folder on a computer or smartphone, you can send it. The receiving device needs to be able to recognize the file type to open it (for example, if the sending devices transfer a PDF document, the receiving device needs an app that reads PDFs).

The limitation of using Bluetooth to transfer data is the size of the files versus the transfer rate. The Bluetooth transfer rate depends on the version:

  • Bluetooth 2.x has a maximum data transfer rate of 2.1 Mbit/s (about 0.25 MB/s).
  • Bluetooth 3.x has a maximum data transfer rate of 24 Mbit/s (about 3 MB/s).
  • Bluetooth 4.x has a maximum data transfer rate of 24 Mbit/s (about 3 MB/s).
  • Bluetooth 5.x has a maximum data transfer rate of 50 Mbit/s (about 6 MB/s).

To use Bluetooth to send an 8 MB photo from one smartphone to another, and both smartphones have Bluetooth version 3.x/4.x, the photo transfers in about three seconds. A single 25 MB music file takes about nine seconds. A 1 GB video file takes about seven minutes. These times reflect the maximum speed, actual data transfer rates are less than the maximum specified.

Compared to other ways of transferring data, Bluetooth is slow. For example, USB 2.0 has an effective throughput of up to 35 MB/s, 11 times faster than the Bluetooth 3.x/4.x maximum rate. USB 3.0, which is the most common, is around 600MB/s. Wi-Fi speeds range from 6 MB/s to over 25 MB/s (depending on protocol version), which is anywhere between two to six times faster than the Bluetooth 3.x/4.x maximum rate.

Tips for Bluetooth File Transfer

To get the best speed and results when transferring files, follow these tips:

  • Disconnect smartphones, tablets, and computers from other Bluetooth devices (for example, wireless speakers and headphones).
  • Some devices may limit the number of files that can be transferred at a given time, so it may be necessary to transfer files one at a time, rather than in batches.
  • Keep the sending and receiving devices as close to each other as possible with a clear line of sight. This maintains the best signal strength that won’t be interrupted by other wireless signals and physical obstacles.
  • Close other apps until all files have transferred. Bluetooth does the sending and receiving, but the device needs processing power to write the data to storage.
  • Troubleshoot your Bluetooth devices if there are problems with pairing.

How to Turn On Bluetooth

The steps to turn on Bluetooth on phones and other devices vary. Here are the general steps, with some examples.

  1. Open the Settings app (the icon resembles a gear). To access Settings on Android phones, swipe down from the top to display the notification panel. To access Setting on Windows PCs, go to the Windows Start menu.

  2. Tap Connected Devices on stock Android. Tap Connections on Samsung. Select Devices on Windows.

  3. Select Bluetooth. For quick access to Bluetooth, swipe down from the top of the screen to display the quick settings panel.

    Bluetooth has its own section in iOS Settings, toggle it on or off in Control Center.

  4. Turn on the Bluetooth toggle switch to display a list of Paired Devices (such as Bluetooth audio devices you’ve paired with before) and a list of Available Devices.

  5. The receiving device is visible (discoverable) to other devices. A timer may count down the duration of visibility, Bluetooth will turn off when it reaches zero. If there isn't a toggle switch, the device is visible while the Bluetooth settings are open.

  6. To send files from a smartphone or tablet to a desktop or laptop PC, make sure the mobile device is connected/paired to the computer (this action is performed on the computer).

  • How do I check what Bluetooth version is on my Android phone?

    The easiest way to find your Bluetooth version is through the handy app AIDA64. Look under System > Bluetooth > Bluetooth Version. Older versions of Android may have it listed under Settings > Apps > three vertical dots > Show All Apps > Bluetooth or Bluetooth Share > App info.

  • How do I play music through Bluetooth in my car from my Android phone?

    First, you'll need to activate Bluetooth on your vehicle. Then, on your Android phone, go to Settings > Connections > Bluetooth > Scan (or turn on Bluetooth first). Once your Android device scans and locates your car, select it, then run your music app.
