Get to Know iMessage
At the beginning, I’d like to give you a brief introduction to iMessage. If you only want to know the iMessage video size limit, just proceed to read the next part.
iMessage is available on all Apple devices, including iPhones, iPads, iPod Touches, Macs, and even Apple Watches. You can use it to send text messages, videos, images, and documents. Furthermore, it enables you to send locations and stickers. What’s more, iMessage uses end-to-end encryption to ensure that your conversations remain private. Only the message sender and recipient can read the messages.
iMessage is deeply integrated with the Apple ecosystem. When you’re communicating with a non-Apple user, it automatically switches to regular SMS or MMS, making it a seamless part of everyday communication for millions of people.
iMessage Video Size Limit
What is the iMessage video size limit? Does Apple publish an official cap? Unfortunately, Apple doesn’t offer any official information about the iMessage video size limit or the iMessage file size limit. I search for information from Apple Support forums, community discussions, and other articles. While Apple has not provided specific public documentation regarding these limits, we can summarize the iMessage video size limit from the collective experience of users.
For iMessage, the video size limit is around 100 MB. Meanwhile, the video duration is no longer than 4 minutes and 20 seconds roughly. You should know that the iMessage video size limit is not explicit. Sometimes, if you send videos larger than 100 MB, you’ll fail to send them in iMessage, or iMessage will convert videos into iCloud links if your videos are stored in iCloud Photos.
If you intend to send large videos via iMessage successfully, you should make sure that the videos meet the iMessage video size limit. Or you can use alternative ways to send large videos without losing quality. For example, you can send videos without losing quality via AirDrop or iCloud. Additionally, you can use a video compressor to reduce file size in advance. How can you compress videos for iMessage? Keep reading.
