How to Convert H264 to H265 (HEVC/x265) While Keeping the Quality?

H.265 encoder has a more advanced compression technology than H264 that it can encode video into a smaller size while keeping the same level of video quality. If you want to reduce the size of your videos yet at the same time don’t want to compromise the quality, then transcode the video codec from H264 to H265 is a good resort.

On this page, you’ll learn how to use the best H265 converter to help convert H.264 to H.265. Free download the converter in advance and let’s get started:

Should I Convert H264 to H265 (HEVC/x265)?

Q: Should I convert my H.264 videos to HEVC/H.265 to save space? Will I lose quality? ------From a Quora user

A: Yes, you should convert your H.264 videos to H.265 to save space and yes, there will be an acceptable quality loss (such loss is not visible to your naked eye). Let me explain in detail at below:

First of all, both H.264 and H.265 are excellent video compression standards to provide good video quality at a relatively small size. H.265 (High Efficiency Video Coding/HEVC/x265) is a successor to H.264 and almost double the data compression ratio than H.264. To put it in other words, you'll get a half size video when you encode video with H.265 instead of H.264. So to conserve more space, you should convert H.264 to H.265. (For more information about these two encoders, please check H.265 vs H.264.)

Second, any transcoding (in lossy formats) will generate data loss. And since both H.264 and H.265 are lossy encoders, the conversion from x264 to x265 will definitely lead to some quality loss. But such quality loss is acceptable for it’s hard for anyone to spot the quality change.

In all, convert H.264 video (especially in high bit-rate) to H.265 will save you much space while preserving the quality. So you should convert H264 to H265.
