There are many ways to go about compressing your iPhone videos, but like most things in life, the simplest option is often the best. Kompresso is a free to use, native iPhone app that uses the powerful processor on your smartphone to compress files. This means there's no need to upload or share your video files to online compression websites.
Most people think of video compression as the last tool in their belt, but it doesn't have to be that way. There are many reasons why you might want to compress videos, even if all you're thinking of is backup.
Data usage and upload issue: When it comes to uploading or sharing videos, file size really hurts. It takes longer to upload large files, and there are sites that won't even allow for videos above a certain size. Not to mention the bandwidth required, and the data charges when you try to upload a 5GB video straight from your iPhone, using 5G.
The playback issue: A large iPhone video plays great on your iPhone, and your Mac, but that might not be the case when you transfer it to your parents' Windows PC and they try to play it on their TV (true story, this happened to one of my wedding videos, which lagged and stuttered like crazy).
What does compressing your videos do?
Good video compression is all about striking a balance between file size and visual quality. Compression algorithms try to reduce the file size while still keeping all the visual elements of the video intact, or at least at an acceptable quality.
In a single frame, the algorithm might compress adjacent pixels with similar color and brightness. For example, it might store color details for a large part of a sky shot in one spot, instead of having data on every single blue pixel.
Of course, once video is compressed, you might notice that the video quality is slightly reduced. You might see visible pixelation, or blockiness in some videos with fast motion. Although, with good programs, this isn't that common. If this does happen, you can try compressing again, just using less harsh parameters, or perhaps without dropping down the resolution.
How to compress vidoes on iPhone using Kompresso
The Kompresso app offers two options for compressing videos. By default, you'll see a simplified three tier option. Add any video and choose between High, Medium, and Low quality. As you change the option, you'll see the file size savings you'll get up top.

Now, you can directly share the video, to save it to the Photos app. Once the new video is saved, make sure you go to the Photos app to delete the old video, and then again, to clear it from the Recently Deleted folder.
Kompresso is free to use for up to three compressions a day, and you can unlock all limits by paying $1.99/month or $9.99 to fully unlock it for life.
