The best mp4 file shrinker to compress my videos for Windows 11
Hi everyone, I've got a bunch of MP4 videos that are taking up way too much space on my Windows 11 PC, and I need to shrink them down without turning them into pixel soup. I prefer something that lets me set a target file size or compression percentage rather than guessing at bitrates.
Has anyone found a reliable, preferably free or low-cost MP4 video shrinker that works well on Windows 11? I'm mainly looking to compress file size for storage and sharing, and I'd love to hear what settings or software you've had the best luck with.

Using discompress-trim as an mp4 video compressor is an excellent choice if you have a very specific goal in mind. It is a free and open-source batch script, but it's important to understand that its primary function is tailored for a single use case: compressing files down to under 25MB for free Discord uploads.
Here is what makes this a unique mp4 video compressor:
- Targeted Compression: The script's main purpose is to automatically adjust bitrate and encoding to ensure your video file ends up under the 25MB limit. This is a very different approach from a general-purpose mp4 video compressor that might focus on quality or file size trade-offs.
- Built-in Trimming: As the name suggests, you can specify a start and stop time, and it will trim the video before compressing it to the target size. This is a handy feature if you only need a specific clip.
- Simple Usage: You can compress files by simply dragging and dropping them onto the batch script or running it from the terminal. For an even faster workflow, you can add the script to your Windows right-click menu.
While a powerful tool, discompress-trim has specific limits that may affect its use as a general mp4 video compressor:
- Hard Bitrate Floor: The script cannot compress video streams below 125kbps and audio streams below 32kbps. This means that for very long videos, it may be impossible to compress them down to 25MB because the bitrate would need to go below these limits. The script will fail in such cases.
- Dependency on FF mpeg: This script is a wrapper for FF mpeg, a powerful command-line video processing tool. You must install FF mpeg on your system for the script to work.
If your goal is to compress videos for Discord's upload limit, this is a fantastic and free tool. If you need a more general-purpose mp4 video compressor with fine-grained control over quality settings, you might find its focus too narrow.

Yes, StaxRip can be an excellent choice as an mp4 video compressor, especially if you prioritize achieving the absolute smallest file size and are willing to invest time in learning its complexities. However, it's important to know that StaxRip is explicitly not a "one-click encoder" and is designed for users who want deep control over the compression process.
If your primary goal is to act as an mp4 video compressor that gives you full access to advanced encoders like x265 and SVT-AV1, StaxRip is unmatched. It serves as a powerful graphical front-end for these professional-grade tools. For power users, this means you can achieve superior compression, resulting in significantly smaller MP4 files compared to simpler tools.
Some users have even found that StaxRip can utilize system resources more efficiently than other popular encoders, potentially resulting in faster encodes for the same settings.
StaxRip's strength as an mp4 video compressor lies in its extensive feature set, which includes support for:
- Modern Codecs: Integration with leading encoders like x264, x265 (HEVC), and SVT-AV1.
- Hardware Acceleration: Support for GPU-based encoding from AMD, Intel, and Nvidia to speed up compression.
- Advanced Filtering: Deep integration with AviSynth+ and VapourSynth, allowing for professional-level filtering like denoising and sharpening before compression.
- Batch Processing: A job queue system to schedule multiple encoding tasks, which is useful for compressing large libraries.
Choose StaxRip if your priority is maximum compression and you are on Windows. If you need a simpler or cross-platform tool, consider HandBrake, which is a great alternative but offers less control for squeezing out every last megabyte.

Using VVenC as an MP4 video shrinker can be an excellent choice, as it is an open-source encoder built to provide the best possible compression for the latest video standard. However, using it is a significant trade-off, as its superior compression efficiency comes at the cost of very high computational complexity, which can make it a less practical choice for many users.
Below is a breakdown of VVenC's core characteristics to help you decide if it fits your needs as an MP4 video shrinker.
How to Use VVenC? VVenC is not a typical point-and-click application. It is a command-line encoder often integrated into more complex workflows.
- The Most Common Approach: You can incorporate VVenC into FF mpeg. FF mpeg supports it as an encoder, but you will need to patch or build a custom version of FF mpeg to include it. This is the most powerful method but requires technical know-how.
- An Alternative: For users on Windows, the "Media Autobuild Suite" is often recommended to streamline this complex build process.
- Finding the Right Balance: You can adjust VVenC's speed with "presets" (--preset faster, --preset medium, etc.) to find the right balance between encoding time and file size reduction.
VVenC is a very powerful and effective MP4 video shrinker in terms of compression, but it might be overkill for simple tasks. It's best suited for users who prioritize maximum file size reduction and are willing to invest the setup time and computing resources required.
