How to transfer large files from a Windows PC to iPhone with no size limit

A large file from a Windows PC to iPhone hits a wall on almost every path: 25 MB in email, 2 GB in messaging apps, a full evening on cloud upload. Here is a path with no cap.

Why this usually goes wrong

Getting files onto an iPhone from Windows means iTunes or the Apple Devices app, iCloud for Windows, or emailing things to yourself. The Apple Devices app syncs rather than copies — what you remove on the PC disappears from the iPhone at the next sync — and anything large has no simple path without the cloud.

Every common path has a ceiling: email stops at 25 MB, WhatsApp and Telegram at 2 GB per file, free WeTransfer at 3 GB every 30 days, and cloud drives at whatever space you have left. Above that people split archives, buy storage or give up. Over a direct connection there is no ceiling, and a broken transfer resumes instead of restarting.

Direct transfer speed is set by your Wi-Fi, not by a server: over home Wi-Fi we measured 17.5 to 49.7 MB/s. From Android to a Mac a cable works too: about 28 MB/s on a USB 2 cable.

How to do it with ZiggSend

  1. Install ZiggSend on the PC from ziggsend.com/windows.
  2. Install ZiggSend for iPhone from the App Store (free).
  3. Connect once: on the iPhone, tap Connect to a computer, pick the PC under Devices nearby (or tap Scan the QR code) and click Allow on the PC after checking the safety code on both screens.
  4. On the PC, click Send files with ZiggSend open on the iPhone screen (the iPhone only receives with the app open). Photos and videos go to the Photos app, other files to the Files app, all verified byte for byte.

It works in both directions: the same pairing sends from the computer back to the phone.

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

Can I send a video the Photos app refuses?

Yes. ZiggSend copies the file as is. Formats the Photos app accepts (H.264, HEVC, ProRes in MOV/MP4) go there; anything else goes to the Files app so nothing is lost.

Do I need iTunes on the PC?

No. Nothing from Apple has to be installed on Windows.

Is there really no size limit?

None. The only limit is free space on the receiving device. We moved 22 GB in one session with 0 failures (Android to Mac, over the cable).

What if the transfer is interrupted?

It resumes where it stopped. Every file is written as a temporary part and only gets its final name after the hash check passes.
