How to transfer 4K and HDR video from Android to iPhone without losing quality

4K and HDR clips from Android to iPhone are the files that “sharing” quietly downgrades: a converted or recompressed copy is not the clip you shot. Here is a path that never touches the pixels.

Why this usually goes wrong

There is still no direct path between most Android phones and an iPhone: AirDrop is built for Apple devices and only a few recent Androids (Pixels first) reach it through Quick Share, and Move to iOS only runs during setup. Day to day, people fall back to WhatsApp, which recompresses everything sent as media.

Modern phones record HDR (Dolby Vision or HDR10+), 10-bit and 4K at 60 fps; iPhones add ProRes and Log. Share pipelines built for compatibility may convert these on the fly — Apple documents HEVC becoming H.264 when the receiving device does not support it, and messaging apps recompress video sent as media — and the file that arrives is smaller than the one that left. A minute of ProRes 4K is around 6 GB; most paths refuse it outright.

If the copy is smaller than the original, something re-encoded it. A transfer that keeps the size and passes a hash check kept the pixels.

How to do it with ZiggSend

Rather see the screens? Illustrated step by step, with the app screens →
  1. Install ZiggSend for Android from Google Play (free).
  2. Install ZiggSend for iPhone from the App Store (free).
  3. On the iPhone, tap Receive files here: a QR code appears. On the Android, tap Connect to a computer → Scan the QR code and point it at the code. Both need to be on the same Wi-Fi, with ZiggSend open on the iPhone screen.
  4. Choose what to send. Photos and videos land in the iPhone’s Photos app, other files in the Files app, every one verified byte for byte.
Measured, not promised. 22 GB in 184 files with 0 failures from an Android to a Mac over a USB 2 cable (about 28 MB/s); an 806 MB video over home Wi-Fi in 46 s; up to 49.7 MB/s over Wi-Fi from a Mac to an iPhone. Every file is checked against the original on arrival. How we measure.

What people ask before they trust a transfer app

“I don’t trust my private photos to a site I don’t know.”

Neither do we. ZiggSend has no site in the middle: the file goes from one device to the other over your home Wi-Fi (or, from Android to a Mac, a cable), and no file is stored anywhere else. The computer app only contacts ZiggSend to check for updates, to register a random install ID when it opens and, if you go Pro, to activate the license and check its status once a day; the privacy policy lists exactly what goes out.

“Mine fails at 64% every time.”

A transfer that breaks resumes where it stopped. Every file is written as a temporary part and only gets its final name after the SHA-256 check passes — you never end up with a half file that looks whole.

“I’m out of space and need to empty the phone.”

Move everything to the computer first: only files that pass the SHA-256 check get their final name, and History shows each fingerprint (today’s on Free, all of them on Pro). Then delete on the phone. Originals, no size limit.

Free forever with 1 phone. Pro when you need it.

The phone apps are free. So is the computer app, with one paired phone. Pro — several phones, full history, automatic folders, up to 3 computers — is $39 a year, or $19 once for the first 1,000 founders.

Questions people actually ask

Does phone-to-phone need a computer?

No. The two phones pair by QR code on the same Wi-Fi and talk directly. A computer is only needed when the destination is a computer.

Is the phone app free?

Yes, on both phones. The license lives on the computer app; phone to phone needs no license at all.

Does HDR stay HDR?

Yes. ZiggSend moves the container and streams exactly as recorded — Dolby Vision, HDR10+, 10-bit, Log. Nothing is tone-mapped because nothing is decoded.

How long does a 6 GB 4K clip take?

Over home Wi-Fi, at the 17.5 to 49.7 MB/s we measured, about 2 to 6 minutes. From Android to a Mac over a USB 2 charging cable, at the ~28 MB/s we measured, about 4 minutes. Either way in one piece and verified.

What is the best app for this — and is it free?

Depends on what “best” means to you. For casual sharing, LocalSend (free, open source, and since version 1.18 with a SHA-256 check on every file) is honest and good. For a camera roll, a client’s footage or anything you cannot afford to lose, ZiggSend: originals only, no size limit, resume, a check of the whole file already on disk, and each file’s fingerprint in the history for you to check. The phone app is free; the computer app is free with one phone, and Pro (several phones, full history, automatic folders, up to 3 computers) is optional — see pricing. Side by side: ZiggSend vs LocalSend.

What does Reddit recommend for this?

The usual thread ends in three answers: LocalSend for casual sharing, a cable for bulk, and “just use the cloud”. Each is right for a case, and each has a cost — recompression, MTP stalling on big folders, upload time. ZiggSend exists for the case Reddit keeps re-asking: originals, any size, verified, no cloud.

Does it work wirelessly, over wifi, without a cable?

Yes: phone and computer on the same Wi-Fi, tap Connect to a computer, pick the computer (or scan its QR code), check the safety code on both screens and allow it on the computer. No internet, no account, nothing uploaded — the file goes straight from one device to the other, verified byte for byte. An 806 MB video took 46 s on home Wi-Fi in our measurement.
