The software supports all formats with no size restrictions, and can even batch compress video files at a time. Next, I will show you how to compress large video files with this 4GB video compressor. Free download Free download the software to get started.

Step 1. Add Large 4GB Video Files

Open WonderFox HD Video Converter Factory Pro on your Windows and enter the “Converter” module. Next, click the "Add Files" button to import the big video files into the conversion list. You can also drag the source files into the program directly. The program has no size restriction and you can add a 2GB video, 4GB video, 5GB video, 10GB video, etc.

Tips: You can click the ▼ button to select an output folder in advance or leave it as default.

Step 2. Choose an Output Format

Click the format image on the right side of the program to unfold the output format list. Head to the “Video” section and select your wanted output format. You can keep the format as the original or try a different type.

Tips: You can choose the H265 profiles and skip step 3 if you want to preserve the video quality.

Step 3. Reduce Large Video File Size

Now, if you want to compress easily and quickly, you can return to the main interface and use the compression button at the bottom to compress the file. Simply click the button and drag the slider to the right to set the compression ratio. When changing the ratio, you can preview the output size in the conversion list. Please note that this method will reduce the bitrate of the video, so the quality will be reduced to varying degrees depending on the compression ratio you set.

Alternatively, you can modify the settings, including the codec, resolution, bitrate, and frame rate in the “Parameter settings” to compress 4GB video files to MB. In addition, you can also use the Trimmer tool under the conversion list to trim the video length to reduce the file size.

Step 4. Export the Compressed File

Finally, hit “Run” to convert the 4GB video file to the wanted size.

“Is there any website that allows me to compress a 4GB video file online for free? How to compress large video files easily?”

When it comes to compressing videos, online services are always first to come to mind. However, it is sometimes difficult to find a good video compressor online to compress large videos. I am sure that you must have been trying hard to find an effective website to convert your large videos, but to no avail. In fact, the maximum upload file size accepted by a browser is 4GB, so you can't really find any online service that allows compressing 4GB videos directly, even with paid services (excluding conversion from URL).

However, you can use FreeConvert and CloudConvert to compress videos up to 1GB online for free. If you're willing to pay, you can upgrade to compressing 2GB videos online or compressing 4GB video files online using FreeConvert. The steps are similar:

• Step 1: Upload the video onto the website.
• Step 2: Select an output format in advance.
• Step 3: Configure the video settings to decrease video size.
• Step 4: Start the compression process.
• Step 5: Download the final file to your device.

Please note that you cannot preview the output size on both websites. Also, considering the processing time, online websites are still not a good choice compared to desktop software.

Video size is closely related to video codec, resolution, bitrate, frame rate and duration. So to make a large video smaller, you need to adjust one or more of these parameters to achieve the desired size. Here is how to shrink a 4GB video file in detail.

1. Compress Large 4GB Video by HEVC/H265 Re-encoding

A codec is a program used to encode or compress video data. There are various video codecs, among which HEVC stands for High Efficiency Video Coding. If your source video is encoded in H.264/MPEG-4 AVC, its size can be reduced by half when re-encoded by HEVC. If it was encoded by a less efficient codec (such as MPEG-4, MPEG-2, XviD, etc.), the resulting file will be even smaller.
Tips: The latest AV1 codec offers higher compression than HEVC, but encoding videos to AV1 will consume more resources and time.

2. Compress Large 4GB Video by Resolution Downscaling

Higher resolution comes at the price of a bigger file size. Lowering the video resolution can reduce the file size significantly.

3. Compress Large 4GB Video by Bitrate Decreasing

Bitrate contributes to file size greatly. Higher resolution usually requires a higher bitrate, hence a bigger size. As you change the resolution, you can decrease the video bitrate to further reduce the video file size, say, you can divide the bitrate by two if you are going to convert video from 1080p to 720p.

4. Compress Large 4GB Video by Frame Rate Dropping

Frame rate is related to the smoothness of the video. However, 60fps is more than enough for human eyes to watch videos comfortably. So changing 60fps to 24fps, the standard frame rate for normal videos, will definitely reduce the file size.

5. Compress Large 4GB Video by Cutting Length

You can also crop or cut out the unnecessary parts from the video to reduce video size to wanted size.

That’s all I want to share about how to compress 4GB video files and even larger files with the best 4GB video compressor.
