When you are curious about how to reduce the size of videos on iPhone, the default tools can quickly assist you. However, the custom options they offer are very limited. You can only roughly adjust the size of the video file, but you cannot compress it to a specific size.

In this situation, you can use AnyRec Free Video Compressor to precisely control the video size by making specific adjustments to detailed parameters.

Step 1. Navigate to the official website of AnyRec Free Video Compressor on your iPhone. Tap the "Add Video" button to upload the video.
