WonderFox HD Video Converter Factory Pro is an all-in-one software with a built-in video compressor that can perfectly compress multiple video files at the same time. Simply import your videos, regardless of format, then set the compression ratio and you're ready for batch compression. Before that, you can also see the approximate output size.

In addition, it allows you to batch re-encode videos to smaller-sized files while maintaining high quality using efficient codecs such as H264, H265/HEVC or AV1. You can also modify the bitrate, resolution and frame rate, and shorten the video length to further compress the video files.

Next, let's see how to batch compress video files using the software.

Before start, please free download free download the batch video compressor and install it on your PC.

Step 1. Add Video Files to the Software

Launch WonderFox HD Video Converter Factory Pro and enter the “Converter” program. Next, click the center + button or the upper-left “Add Files” to import your videos into the program. Alternatively, you can drag the source files directly into the interface.

At the bottom of the workspace, click the ▼ button to set an output folder in advance.

Step 2. Choose an Output Format

Open the right-side output format list and go to the “Video” category. Select your preferred output profile from the options below.

Tips: You can choose the H265 profile ("H265 for MP4" or "H265 for MKV"). This codec can re-encode your video to a much smaller size file without damaging the video quality. Note that the process is resource-intensive that it converts only 1~2 files at a time. But the speed can be greatly improved if your computer supports hardware acceleration.

Step 3. Set a Compression Ratio

In the main interface, click the compression button and drag the slider to the right to set a compression ratio. As you drag the slider, you can see that the output size changes in real-time. Remember not to set the compression ratio too high if you want a decent output video quality.

Tips: Besides using the compression button, you can also go to the “Parameter settings” to downscale video resolution, bitrate, and frame rate to reduce video file size. For other methods for compressing videos, please refer to How to Compress Video from GB to MB

Step 4. Batch Compress Videos at Once

Finally, click the “Run” button to compress multiple videos at once. It will take some time to compress the video files depending on the encoding settings you set.
