How to Compress Large MP4 Files

Due to their high quality MP4 files may take up a lot of space on flash drives, and it takes forever for them to be uploaded and processed online. This problem can be solved by compressing such videos.

Movavi Video Converter can easily compress MP4 (and files in other formats too) so that you can free up some space on your hard disk. Here, in this article, we will tell you how to reduce the size of any file using this software.

This is what you’ll need to do, in short:

  • First, you need to upload your MP4s to the converter. You can do it either via Add Media button or simply by dragging and dropping them into the program window.
  • Next, choose the appropriate format.
  • Then select the folder where all the converted files will be put.
  • Finally, click Convert and your files will be ready in no time.


You can upload any number of files – the program estimates the CPU load so that all processor cores function more efficiently. This will enable you to convert several files at once. You can even set a Watch Folder – upload all files in one place, establish the parameters and convert them automatically.


Movavi Video Converter supports a wide range of video, audio, and graphic formats: MP4, AVI, WMV, MOV, MP3, FLAC, OGG, JPEG, GIF, PNG, and lots of others. Therefore you can convert media files between any formats, including the scenario when you save only the soundtrack from a video or turn a video into a GIF animation.

Video formats also differ in codecs and resolutions. The lower the resolution – the smaller the file size. Choose the combination of a codec, a resolution, and a format from the list – there are more than 180 possible variants. You’ve seen the available formats above, as for codecs – you can choose between MPEG and H.264. The latter provides better compression, so you’d probably want to go with this codec.


The high bitrate of the file is one of the reasons of its large size. By clicking on the approximate future size you can change it the way you want. However, reducing the size will affect the bitrate and the quality.

Basically, that’s all you need to know about file compression in Movavi Video Converter. However, there are some extra useful functions and tools:

  1. Built-in editor where you can enhance your videos and audio files:
  • stabilize camera shake,
  • normalize volume
  • remove noise
  • adjust colors
  • add subtitles
  • apply a watermark
  • crop, rotate and trim files

  1. Mobile presets

If you need to compress MP4 for viewing on your portable device, there is a list of presets for smartphones, tablets, TV sets and even game consoles. Just choose the appropriate preset and your files will be converted with all the necessary settings.

  1. Ultra-fast conversion

The program makes use of the latest NVIDIA and Intel technologies that accelerate the speed of conversion. For even faster conversion you can use SuperSpeed mode (however, you cannot use it for compression).

Here’s all you need to know about file compression and conversion with Movavi Video Converter. The process is really simple so it won’t take you much time to reduce the size of multiple files at a time.
