How to send large files from an iPhone

To send a large file from an iPhone, use AirDrop if the recipient is nearby with an Apple device, Mail Drop in the Mail app for files up to 5 GB, an iCloud Drive link, or a transfer link opened in Safari when the recipient uses Android or Windows or the file is bigger. Messages and most chat apps are the options to avoid for big videos, because they often compress them.

The right choice depends on where the file is going and how big it is. Below, each method with its official limits as of October 2026, a quick decision table, and the settings that make sure you send the original file rather than a smaller copy.

Which method should you use?

1. AirDrop: the fastest option nearby

AirDrop sends files directly between Apple devices over Wi-Fi and Bluetooth, without using your internet connection, and Apple does not publish a size limit. Both devices need to be nearby with Wi-Fi and Bluetooth on. Recent versions of iOS can finish a started transfer over the internet if you move out of range, controlled by the Use Cellular Data switch in Settings › General › AirDrop, and since iOS 26.2 a recipient you do not know may be asked to enter an AirDrop code.

AirDrop is no longer Apple-only: since November 2025, Google has made Quick Share work with AirDrop, first on the Pixel 10 and now on Pixel 8a and later plus some Samsung, OPPO, OnePlus, vivo, Xiaomi, HONOR and Motorola phones. On the iPhone, set AirDrop to “Everyone for 10 minutes” to receive from them. Details in our guide on moving files between Android and iPhone.

2. Mail Drop: up to 5 GB by email

iCloud Mail limits messages to 20 MB, but the Mail app can switch to Mail Drop for bigger attachments. Apple uploads the files to iCloud and sends a link instead; the recipient can be on any email service. Mail Drop handles attachments up to 5 GB, the files expire after 30 days, and they do not count against your iCloud storage (within a 1 TB Mail Drop allowance).

1. 1

   Step 1

   Create the email in Mail

   Attach the file or insert a photo or video from the format bar.

2. 2

   Step 2

   Tap Send

   If the attachment is too large, Mail offers to use Mail Drop. Accept.

3. 3

   Step 3

   Wait for the upload

   Keep Mail open on Wi-Fi until the message is sent; large uploads take time on cellular data.

3. iCloud Drive: share a link

Save the file to iCloud Drive in the Files app, then use Share › Share a Link (or Collaborate, depending on your version). Anyone with the link can download it, and you can stop sharing later. The file counts against your iCloud storage, which is 5 GB on the free plan, and Apple notes that moving the file breaks the link. It is a good choice for files you want to keep, less so for one-off deliveries that eat your storage.

4. A transfer link from Safari, for any recipient

When the recipient uses Android or Windows, or the file is over 5 GB, a transfer link is the most universal option. There is nothing to install: Transfr runs in Safari, sends up to 100 GB per transfer on its free plan without an account, and gives you a link to paste anywhere, or emails it for you. The recipient downloads the original file on any device.

1. 1

   Step 1

   Open Transfr in Safari

   Go to Transfr. No app or account needed.

2. 2

   Step 2

   Add the files

   Tap to add files and choose Photo Library, or Browse to pick from the Files app. To be sure you send untouched originals, save the video to Files first and pick it with Browse: the photo picker may convert some formats.

3. 3

   Step 3

   Choose link or email

   Copy the link for WhatsApp, Messages or Slack, or enter up to 10 email addresses.

4. 4

   Step 4

   Keep Safari open

   Stay on the page with the screen on until the upload finishes. If the connection drops, the upload retries by itself.

5. WhatsApp, as a document

WhatsApp compresses photos and videos sent as media, even when you choose HD. Sending the file as a document raises the limit to 2 GB and delivers it as a file. Our WhatsApp file size limit guide explains the details.

6. Messages: convenient, but not for originals

Apple does not publish a size limit for iMessage. For text messages sent over MMS, carriers set attachment limits and the iPhone can compress photos and videos when necessary. RCS, available on iPhone since iOS 18 with supported carriers, handles higher-resolution media than MMS, but Apple does not give a size limit either. There is also a Low Quality Image Mode in Messages settings that deliberately shrinks photos. For anything that must arrive in full quality, send a link instead; see how to send video without losing quality.

Why is my iPhone video too large to send?

Modern iPhones record high-resolution video at high bitrates, and every step up in resolution or frame rate makes files bigger; Apple notes that ProRes files can be up to 30 times larger than HEVC. For comparison, YouTube’s recommended bitrate for 4K at 60 frames per second, 53–68 Mbps, works out to roughly 400–500 MB per minute. The camera settings show an estimate per minute for each format under Settings › Camera › Record Video. If you regularly send videos, consider whether you really need 4K60 for everyday clips; for footage you deliver professionally, keep the quality and send a link.

How to make sure you send the original file

• Camera format: Settings › Camera › Formats offers High Efficiency (HEIF photos, HEVC video) or Most Compatible (JPEG and H.264). High Efficiency files are smaller; Most Compatible ones open everywhere.
• Share options in Photos: when you share, tap Options to choose the format (Automatic, Current or Most Compatible). Choose Current to keep the file as it is. All Photos Data, which includes edit history and metadata, works with AirDrop.
• iCloud Photos with Optimize Storage: the full-resolution file may be in iCloud rather than on the phone; make sure it is downloaded before sending.
• Avoid screen recordings and chat re-shares, which are re-encoded copies.

Sending from iPhone to a Windows PC or Mac

To your own Mac, AirDrop is the obvious answer. To a Windows PC, the simplest routes are a transfer link opened on the PC, iCloud for Windows, or a USB cable with the Photos app on Windows for camera-roll imports. If the PC belongs to someone else, a link avoids installing anything. See also our pages on sending large files from iPhone and on Windows.

Tips for big uploads from a phone

• Use Wi-Fi. Median mobile upload speeds were around 10 Mbps in the US and UK in September 2026 (Ookla), so a 10 GB video can take over two hours on cellular data. Our upload time table has the details.
• Plug in the phone and turn off Low Power Mode during long uploads.
• Free up space: the system may need room to prepare large exports.
• Pause iCloud Photos syncing if it competes for bandwidth, then resume it afterwards.
