Before you begin

Make sure that your iPhone or iPad is set to use the most compatible file formats. On your device, go to Settings > Camera > Formats, and then tap Most Compatible. Refer to Apple's support site if you need more information about High Efficiency Image File (HEIF) formats.


Tap your profile picture, tap Advanced, then select Compress Files Before Sending.


Select a compression setting:

  • Never—Images and videos you send will not be compressed.

  • Ask—You'll be prompted if you want to compress the file size, everytime you send images and videos.

  • Always—All images and videos you send will be compressed.


You can change the settings at any time.

Tap your profile picture, then tap Advanced and select Send Reduced File Size.


If you need to send a file at the original size, you can turn off the setting at any time.
