What to Do When iPhone Videos Are Too Large to Email?

Some of the footages can easily cross the file size limit for attachments set by email services. If you record 4K UHD high frame rate or slow motion videos and want to share them via email, it's likely to refused by email services because of big file size. Here are some options to get rid of the problem.

Cut: Under the video information section, there's an option to cut your iPhone video. Click the Cut icon and the Cut window pops up.

Send Videos to Email on iPhone Using Mail Drop

You can turn to Mail Drop to email videos above the maximum size permitted by email service providers using iCloud. Mail Drop allows you to add video attachments up to 5GB. To turn Mail Drop on, tap Mail > Preferences > Accounts > Advanced, and select "Send large attachment with Mail Drop." If your iCloud is signed in, video attachments are automatically sent using Mail Drop.

Make sure your iPhone is running iOS 9.2 or later. The email receiver has 30 days to download the attachments. It may take a long time to finish the upload process if your internet connection is slow and the size is large. Another disadvantage of sending large video from iPhone to email via Mail Drop includes the limit on the number of downloads. Apple states that "the recipients might not be able to access your attachment if the link has an excessive amount of downloads or high traffic". However, we are not sure what amount is considered excessive downloads. If you get a large video to share with quite a few people via email on iPhone, Mail Drop might not be the best way.

Use Other Cloud Services for Big Videos

It's a popular option to upload videos from iPhone to cloud services and get a link to share a file via email. Commonly used services include Dropbox, iCloud Drive, Google Drive, to name a few. They can work as good alternatives to Mail Drop for sending large video files from iPhone to email. But such cloud services have their own file limits and disadvantages, too, for example, iCloud Drive counts against iCloud free storage, Dropbox may compress your footages. It also fixes iPhone video too large to email by uploading videos to YouTube and then obtaining a link.
