8 Best Free HEVC to MKV Converter Online Services

Here is a list of best free HEVC to MKV converter online services. HEVC (High Efficiency Video Coding) or H.265 is a video compression standard, designed to improve video quality and overall compression efficiency. HEVC can store videos of better quality in a much smaller package compared to its predecessor H.264 (AVC). The popularity of HEVC videos is growing day by day. However, special hardware requirements to decode and play HEVC videos do affect the rapid adoption of this format. On the other hand, MKV (Matroska Video) is a popular multimedia container that can carry video, subtitles, audio, meta tracks, etc., information. Similar to HEVC, it can also store high-definition videos. At times, it is necessary to convert videos encoded in one video format to another video format. If you also want to do that, then check out these HEVC to MKV converter online services.

Through these online services, users can convert HEVC videos to MKV, MOV, MP4, 3GP, etc., formats. Some of these services can batch-convert multiple HEVC videos to MKV format.

Frequently Asked Questions

Is HEVC the same as MKV?

No, HEVC and MKV are not the same thing. They serve different purposes. HEVC (High Efficiency Video Coding) is a video codec, which means it's a set of instructions used to compress video data. Think of it like a language for video compression. HEVC is also known as H.265 and MPEG-H Part 2. It's a newer and more efficient codec than the widely used H.264 (AVC), meaning it can achieve the same video quality at a smaller file size or higher video quality at the same file size. On the other hand, MKV (Matroska) is a container format, which means it's a file that can hold multiple data streams, such as video, audio, subtitles, and chapters. Think of it like a box that can hold different things. MKV is an open-source format that's known for its flexibility and support for a wide range of features. It's not limited to any specific video or audio codec, so it can contain HEVC video, H.264 video, or any other type of video data.

Which is better MKV or HEVC?

If you need a flexible container format that supports diverse features like multiple audio tracks, subtitles, and chapters. Plus, if you want open-source and royalty-free options, then choose the MKV format. If you prioritize smaller file sizes while maintaining good video quality then select the HEVC format.

How to convert HEVC to MKV for free?

You can use above mentioned HEVC to MKV converter online services to quickly convert HEVC videos to MKV and other common video formats like MP4, AVI, MOV, etc.

Is HEVC a h265?

Yes, HEVC and H.265 are the same thing! They are just different names for the same video compression standard.

Is HEVC better than HD?

It's not quite accurate to say that HEVC is "better" than HD because they address different aspects of video quality. HEVC can be applied to both HD and non-HD videos, improving their compression efficiency regardless of resolution. HD provides higher resolution compared to SD, regardless of the codec used.
