You can also take advantage of online converters to crop an MP4 file. Compared with desktop software, the biggest advantage of online tools is that you don’t need to install any plug-ins or software on your computer. Here are some of the good online MP4 croppers:

After testing most popular online tools, I find that the common defects of them are slow upload and process speed, especially when I crop large MP4 files with them. The possible causes are unstable server and varied internet connection. What's more, almost all online converters have the maximum upload limits, so it's not recommended to convert large files with them. Meanwhile, if you meet with unexpected conversion error, long conversion time or something like that, resubmit the files to fix the problem. And you can never be too careful about those pop-up ads and other misleading information on those websites.
