Short answer

Same ecosystem: AirDrop between Apple devices, Quick Share between Android devices. Cross-platform: cloud storage or a local network transfer app. Very large files: a USB drive or a cable is still fastest. Email is the worst option for anything over a few megabytes.

There's no single best method, only a best method for a given combination of devices, file size and whether you have internet. Knowing the four main options and when each applies covers essentially every case.

Step by step

  1. Between Apple devices, use AirDrop.Both devices need WiFi and Bluetooth on. It transfers directly over a local connection, so it's fast and doesn't use data.
  2. Between Android devices, use Quick Share.The equivalent to AirDrop. Both devices need to be discoverable.
  3. Across platforms, use cloud storage.Upload to Drive, OneDrive or Dropbox and share a link. Works everywhere, but the file goes via the internet twice.
  4. For a large transfer on the same network, use a local transfer app or a shared folder.Much faster than cloud, and it doesn't consume your upload allowance.
  5. For very large files, use a USB drive or a direct cable.Still the fastest option for tens of gigabytes, and the most reliable.
  6. For a phone-to-computer transfer, use a cable and the file browser.Android appears as a drive; iPhone photos import through Finder, Photos or the Apple Devices app on Windows.
  7. Check whether the transfer preserved quality.Some messaging apps compress photos and videos heavily. If quality matters, don't send media through them.
  8. For sensitive files, use a method with encryption and consider password-protecting the file.Email attachments and open shared links are the least private options.

Tips

  • Messaging apps are convenient and compress aggressively. For photos you care about, use a proper transfer method.
  • Cloud share links often default to 'anyone with the link'. Check the permission if the content is private, and set an expiry where the service supports it.
  • For a one-off large transfer with no good network, a USB stick genuinely remains the fastest option.
  • When moving to a new phone, use the manufacturer's migration tool rather than transferring files manually — it moves settings and app data too.

Common mistakes

  • Emailing large attachments — Most providers cap attachments at 20–25MB, and it's slow and wasteful even below that.
  • Sending photos through messaging apps when quality matters — Most compress heavily and irreversibly.
  • Leaving share links open indefinitely — Anyone who ever had the link keeps access. Set expiry or revoke afterwards.
  • Deleting the original before confirming the transfer — Verify the file opens at the destination first.

Questions people ask

What's the fastest way to transfer a very large file?

Physical media or a direct cable, for anything in the tens of gigabytes. Over a local network, a direct transfer app beats cloud storage, since cloud means uploading and downloading the whole file.

How do I transfer between iPhone and Android?

Cloud storage works reliably in both directions. For a full device migration, both Apple and Google publish migration tools that handle contacts, messages and photos.
