From 50MB to 5MB – How to Compress MP4 File in Seconds

After taking a few videos, you may want to upload them to Instagram story or share them with your friends. However, most social media platforms have a file size limit for uploads. So, when you send an MP4 video through WhatsApp or add an MP4 attachment into your email, you may find them too large to upload sometimes.

Therefore, to solve this problem, you need to compress MP4 files, or in other words, help your videos lose weight.

The following article will guide you to reduce the size of MP4 videos without compromising on display effects.

Part 2. How to Compress MP4 Using an Offline Freeware

If your network is not that stable, you’d better choose to compress video offline on your desktop, which avoids the influence of network status.

It supports over 1,000 formats and there will be 10 output resolution options for you to choose.

Step 1. Launch Video Converter Ultimate on your computer.

Select Tools

Step 3. For the Preset above, Fast 480p30 will be fine. Go to the Video tab and check if the video codec is H.264 (x264). And choose the framerate depending on your source video. If you don’t know how to choose, just pick Same as source. Tick Constant Framerate to ensure better compatibility. Enter an Average Bitrate (kbps) for the video (between 5,000 and 10,000).

For beginners, we actually don’t recommend you to use HandBrake, because it is hard to understand and adjust the parameters. And it really takes a long time to obtain the compressed file.

Part 4. FAQs of MP4 Compressing

1. Can ffmpeg compress MP4?

Yes, you can use a following sequence of characters to compress MP4 file:
$ ffmpeg -i input.mp4 -vcodec h264 -acodec mp2 output.mp4
But some people may find it increased the size instead of decreasing when the video is small enough.

2. Can HandBrake export WMV, MOV and FLV?

HandBrake only supports you in compressing videos to MP4(.M4V) and MKV, which means it cannot export files in other formats, such as WMV, MOV, FLV, AVI, etc. If you use HandBrake to get compressed videos, then you need to convert MP4 to WMV or other formats by yourself.

3. Does compressing MP4 videos lose quality?

The quality will definitely lose, more or less, when we compress MP4 from full size to a smaller size. However, with a professional video compressor like FVC Free Video Compressor and Video Converter Ultimate, you can maintain the original image quality as far as possible. Also using a good MP4 player to play MP4 files may help you get high-quality output.


So far, we have introduced you 3 methods to compress MP4 to smaller size. If you hate to install too much software to your computer, you can try FVC Free Video Compressor which is online and free to use. But if you need a mighty video processor, Video Converter Ultimate is your best choice. Hope you find this post helpful and don’t forget to leave us a message to express your opinions.
