M4V is a video container format similar to MP4. The main difference between them is that M4V is developed by Apple and may optionally be protected by DRM copy protection.

Yet, instead of purchasing more space, you can compress M4V files to free up device storage. In the next part, I will introduce a quick and easy way to shrink M4V videos. Read on.

Step 1. Load M4V File(s)

Launch HD Video Converter Factory Pro and select Converter among the five modules (Converter, Downloader, Recorder, GIF Maker, Toolbox). In the next window, click + Add Files to import the M4V video(s) into the converter. Or you can drag and drop the file(s) into the program directly.

Step 2. Choose Output Format

On the right side of the workspace, click the format image to open the output format library. Then go to the Video category and pick your preferred output video format, e.g. M4V, MP4, MKV

Step 3. Compress M4V Files

On the main interface, click the compression button below (on the left of the Run button) and drag the slider to the right to batch compress the files. The slider is more to the right, the file is smaller (The theory is to reduce the video bitrate. So remember not to push the slider to the far right, or the video quality is ruined). If you are OK with losing some video quality, you can directly lower the resolution from the Quick setting to reduce your video file size as well.

Tips: If you don’t want to lose quality, you can choose MP4 or MKV as output format in Step 2 and then change the video encoder to H265 in the Parameter settings. Alternatively, you can choose H265 for MP4 or H265 for MKV from the output format library directly and skip this step.

Step 4. Start Compressing

Click the bottom triangle button to set an output folder or leave it as default. Finally, click Run to start the compressing process.

Can I Compress M4V Video Online?

You might probably have heard of online conversion and online downloading, and you wonder whether you can complete M4V compression online. The answer is, of course, you can compress M4V video online since there are quite a lot of online video compressors that can help you with it.

However, just like the online converters and online downloaders, online compressors also face many restrictions. The primary drawback is their long process time. Unlike the desktop software, online compressors require two more steps besides compress - upload and download, which is a time-consuming process. And if you don’t have a strong and stable internet condition, the situation could be even worse. Moreover, many online compressors also have size and length limits on the video to be uploaded. So, online tools are not suggested when compressing large video files.

However, if you only have one or two small M4V files, using online compressors is a quick and convenient solution. Take Aconvert for an example. Here is how to reduce M4V file size online with Aconvert.

Step 1. Visit

Step 2. Click Choose Files to upload your M4V file. (Maximum file size 200MB)

Step 3. Next, change the Options to Change size, bitrate or frame rate.

Step 4. Click to open the Video size drop-down list and select a video resolution lower than the original one (The lower the video resolution, the smaller the file size.)

Step 5. You can continue to change the video bitrate and frame rate to a smaller figure to reduce file size. But that will lead to further video quality loss.

Step 6. Finally, click Convert Now! to start the M4V compression.
