There is no built-in iOS function for compressing videos. However, before recording, iPhone owners may change the size of their video recordings in the camera settings. Using a third-party tool such as Video Compress, you may decrease the file size of a video after it has been recorded.

We may change the camera settings on the iPhone to record movies at different resolutions and frame rates. On the iPhone 8, 8 Plus, or X, for example, go to Settings >> Camera >> Record Video, then select a video resolution/frame rate. If you want to edit your movie later, tap Edit Movie. Here's how:
To start editing your movie right away, first make sure that it's saved by going to Menu >> Home. Now you can tap the red button in the top-right corner of the screen to go straight into edit mode.
While in edit mode, you can pinch out from within the screen to zoom in on a section of the movie, or double tap the screen to exit edit mode and return to playback mode.
If you want to delete a section of the movie, simply drag the playhead along the timeline and click the blue trim button on the right side of the screen when you're done editing.
You can also tap the red button again to leave edit mode.
Finally, if you want to save your movie directly to Photos, go to Menu >> Save To. Choose between various formats such as MOV and MP4, and select a location on your device for saving the file.
Reducing an image's physical size is a straightforward approach to compress it without sacrificing quality. When you resize an image, the image size is automatically compressed. That means you may reduce the size of your photograph without sacrificing quality. The two main types of photo resizing are horizontal and vertical reduction. With these methods, it's easy to shrink an image to a desired size while maintaining its original aspect ratio.
The best way to reduce the size of an image is to use software that allows for precise control over the compression process. This way you don't lose quality due to excessive compression or inaccurate measurements. There are many free tools available online that allow you to resize images with good results. Some popular ones include: Pixlr-o-matic, PhotomiX, TinyPic, and Voila.
You should also try using mirroring or flipping techniques when reducing the size of an image. These methods help preserve the integrity of the image by copying its features. For example, if you flip an image horizontally, the result will be a new image with the same information as the original but in reverse order. This technique can be used to create small thumbnail images from larger ones.
