How to reduce video size without losing quality.

Learn more about reducing video sizes by compression or conversion so you can easily edit, share, and upload your videos.

Video-making opens up a complex world of storytelling — a world full of dynamic shots, unique transitions, and eye-catching special effects. Putting all of these elements together, though, often results in large file sizes that may be a challenge to work with and share with others. Let’s look at the ways you can reduce video sizes to create more workable files.

Ways to reduce video file size by compression.

To make a video file smaller, you can compress it. There are two types of compression. Lossless compression is a way to reduce file size without losing quality — this is what happens anytime you create a ZIP file. In this scenario, the original data is preserved and nothing is thrown out. Lossy compression, on the other hand, shrinks the file size by throwing out extra, unnecessary data.

You’ll want to choose lossless compression if you want to preserve your video in its original quality. If a similar copy is “good enough,” though, lossy compression can make your video files even smaller. You can easily compress your video file with online compression tools or a media encoder.

Reduce file size by conversion.

You can also convert one video format to another to reduce its size. For example, if you convert an MOV to an MP4, the resulting file size can be as small as one-tenth of the original size, with nearly no loss of quality.

Like compression, there are free online tools for converting your video files too. These tools offer varying size limits and degrees of control over the process.
