Why Should You Convert MP4 to H265/HEVC?

MP4 is a video container format used to store video, audio, codecs, and other metadata. HEVC (H265/x265) is a video codec used to encode and decode digital video.

When we talk about converting MP4 video to HEVC, we usually mean re-encoding the MP4 video using the HEVC codec. Because HEVC is a high efficiency video codec, an MP4 video encoded with HEVC can provide up to 50% more data compression than MP4 encoded with H264 or MPEG4 at the same level of video quality. In other words, converting MP4 video to HEVC will help you cut the file size in half without ruining the video quality.

Therefore, converting video to HEVC is a good option if you want to save space on your device without affecting your viewing experience. For this type of conversion, all you need is a reliable desktop video converter such as WonderFox HD Video Converter Factory Pro. It is a simple but powerful HEVC converter that can help you transcode MP4 to HEVC at extremely fast speeds (supports hardware acceleration). The tutorial below will detail how to convert MP4 to H265. Please read on.

Fun Fact:

All video transcoding leads to video quality loss to some degree. The difference is that some conversions won’t cause a visible quality drop, such as using the H265 codec. The only lossless video conversion is changing the video container, which is also called remux.


Some online video converters can convert MP4 to x265, too. But we don’t suggest them, for they usually process slower (considering the upload time and your network condition) and are covered with ads. The desktop software, however, is free of those limitations.

That’s all for how to convert MP4 file to HEVC with the recommended MP4 to HEVC converter. If you have any questions during the conversion process, you can contact me on Twitter. I’ll be glad to help. Thanks for reading.
