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
- 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.
- Between Android devices, use Quick Share.The equivalent to AirDrop. Both devices need to be discoverable.
- 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.
- 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.
- For very large files, use a USB drive or a direct cable.Still the fastest option for tens of gigabytes, and the most reliable.
- 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.
- Check whether the transfer preserved quality.Some messaging apps compress photos and videos heavily. If quality matters, don't send media through them.
- 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.
