1. Choose a Reliable Video Compressor
The first step is to select a video compressor that meets your needs. Numerous free and paid options are available online. Some popular choices include HandBrake, FFmpeg, and Online-Convert. Do your research to find the best fit for your specific requirements.
2. Set Your Desired Output Size
Once you have chosen a video compressor, it’s time to set the desired output size for your MP4 file. Most compressors allow you to specify the exact file size you want. Alternatively, you can choose from predefined presets that optimize the file size for different purposes, such as email, web, or social media.
3. Adjust Video Resolution
Video resolution plays a significant role in file size. Reducing the resolution will result in a smaller file size. For example, converting a video from 4K to 1080p or 720p can drastically reduce the file size without noticeably affecting the video quality.
4. Lower Bitrate
The bitrate determines the amount of data used to encode the video. A higher bitrate results in a larger file size but also better video quality. Reducing the bitrate can significantly shrink the file size, especially for videos with high motion or complex details.
5. Use Variable Bitrate Encoding (VBR)
Instead of using a constant bitrate, VBR (variable bitrate encoding) dynamically adjusts the bitrate based on the video content. This allows for higher bitrates in complex scenes and lower bitrates in less detailed areas, resulting in a smaller file size without sacrificing quality.
6. Crop Unwanted Areas
If your MP4 file contains unnecessary areas or black bars, cropping them out can reduce the file size. Most video compressors offer a cropping feature that allows you to remove unwanted portions of the video.
7. Convert to a More Efficient Video Codec
Consider converting your MP4 file to a more efficient video codec, such as H.265 (also known as HEVC). H.265 offers better compression than the traditional H.264 codec, allowing for smaller file sizes with comparable or better video quality.

FAQ about How to Shrink MP4 File Size
1. How can I reduce the file size of an MP4 video?
- Answer: You can use video compression tools or software to reduce the file size while maintaining the video’s quality.
2. What are some free online tools for compressing MP4 videos?
- Answer: HandBrake, VideoSmaller, and Clideo.
3. How do I use HandBrake to shrink an MP4 file?
- Answer: Import your MP4 file, select an output file format (e.g., MP4), adjust video and audio settings (e.g., bitrate), and click "Start Encode."
4. What does bitrate affect in MP4 files?
- Answer: Bitrate determines the amount of data used per second in the video, affecting both file size and video quality. Lower bitrate values reduce file size but also reduce video quality.
5. Can I compress MP4 videos without losing quality?
- Answer: To some extent. Using high-quality compression settings can minimize quality loss while reducing file size.
6. How do I shrink an MP4 file using VLC Media Player?
- Answer: Open the MP4 file in VLC, go to "Media" > "Convert/Save," select an output file format (e.g., MP4), adjust video settings (e.g., resolution), and click "Convert."
7. What is the difference between re-encoding and transcoding?
- Answer: Re-encoding involves changing the video codec, while transcoding involves changing both the codec and the container format.
8. How can I compress MP4 videos for email or social media?
- Answer: Use pre-defined compression settings or tools specifically designed for optimizing videos for smaller platforms.
9. Is it possible to reduce the file size of an MP4 video by half?
- Answer: Yes, but it may require significant reduction in video quality. Aim for a 20-30% reduction to preserve acceptable quality.
10. Can I compress MP4 files on a Mac or Windows computer?
- Answer: Yes, there are various software options available for both macOS and Windows that allow you to compress MP4 files.
