Myra updated on Feb 14, 2023 | Home > Video Converter Tips

Have you ever wondered why some people prefer to make a video file smaller without care for quality loss? If you are the type that always likes to keep large video sizes as they are just because you don't want to reduce quality, then you need to learn some advantages of video compression.

Although making a video file smaller doesn't have that many advantages, and there is still the risk of video quality loss, you need to know that; there is nothing like unlimited storage space. Even if you buy all the premium cloud storage, you can't get anything like infinite GB, there will always be a limit, and different social media platforms also impose their video size limit.

Also, as we go about our everyday life, we get more moments to capture, videos to save, and even more to post/upload. Compressing videos makes your video files smaller, making it easier to keep them, send them to friends, or post on social media, and we believe just this one reason is enough to teach you how to compress video files. We have a variety of tools that can handle video file compression.

How to Reduce Video File Size on Mac with Handbrake

Handbrake is free software that can be used for video editing functions like converting and compressing, cropping and resizing video, restoring video quality, etc. Handbrake works with editing codecs, so it is straightforward to compress video without any quality loss. It doesn't support a lot of formats, and it doesn't have a lot of features, but it is free, and there is no loss in quality, so we are not complaining.

How to Compress Video on Handbrake

Step 1. Download and Install the software

Handbrake is not built like iMovie and QuickTime, so you'll need to download it. Go to the Handbrake official website to get the latest version or one compatible with your computer.

Step 2. Upload Video

Launch the software after installing, and on the main screen, click on the box and select the video to compress from your Finder.

Step 3. Set Compression options

Under the Video tab, change the video codec from h.264 to h.265 because h.265 has better compression than h.264, but you can also choose to leave it as is. Next, change the frame rate to 'same as source' if it is not there by default, and check the Constant frame rate option. Under the optimize option, drag the slider to suit your compression need. Very fast makes the compression quicker but doesn't compress size much, and very slow takes time to complete but compresses video size much better. Go under audio and raise the bitrate to 320.

Step 4. Compress

That's all for the setting, and you need to click on Browse and select where you want the video to be saved, then click on the Start Encode button.
