How to Convert HEVC to MP4 with Best Quality

Have some 4K and HD HEVC videos but fail to play them on PC or TV? HEVC videos play with endless stutters? You can just convert HEVC/h.265 videos to the more friendly MP4 format. In this post, we'll share the best ways in 2022 to convert x265 (H.265/HEVC) to MP4 (H.264/MPEG) on Windows (11/10) and Mac.

What Is HEVC?

HEVC (x265, H.265, MPEG-H Part 2) is the most popular successor to the widely used AVC (H.264 or MPEG-4 Part 10). HEVC is able to maintain the same video quality at half the bitrate as AVC MP4. Therefore, it's widely used in ultra HD video compressions up to 8K UHD. You may get videos labeled with H.265, HEVC, and x265(x265 is an open-source HEVC encoder designed to encode videos into H.265/HEVC).

Why Convert HEVC/x265/H.265 to MP4?

While HEVC files are twice compressed as MP4 videos, H.265 is far less compatible than AVC. Many popular devices still don't support the HEVC codec yet or have trouble handling HEVC videos. For example, Adobe Premiere Pro won't import HEVC from iPhone properly and Microsoft doesn't provide support for HEVC codec. HEVC also requires significant computational resources, making it hard to open HEVC videos on older devices. So it is necessary to convert HEVC/x265 to MP4.

#6 Convert HEVC to MP4 Free Using Online Services

Searching for "HEVC to MP4", you'll find the first page on Google is dominated by online services, such as anyconv.com, onlineconverter, FreeFileConvert, convertio, onlineconverterfree, etc. Online X265 to MP4 video converters are mostly free and easy to use, requiring no software installation.

If you're a casual video converter user and the file you want to process has a small size (less than 200-500MB), it's fine. Otherwise, don't bother yourself with online video converters, they are a waste of time. Most if not all such online services have strict file size limits (max 200MB or 500MB for free users), ads, redirects, and slow processing speed.

Note: HEVC video decoding is CPU intensive. Online services always crash and fail to handle the HEVC codec. We highly recommend you use a desktop program to transcode HEVC video files.

Warm Prompt: someone is searching for an HEVC video converter for mobiles to decode and re-encode x265 to MP4 H.264 on Android or iDevices. Forget this. If your tablet or phone is too old for decoding and playing back x265 HEVC footage, it will perform even worse in decoding and re-encoding x265 files. Your energy and time will be badly saved only when you conduct x265 to MP4 conversion tasks on a more powerful PC using a GPU hardware accelerated HEVC video converter!
