How to Convert H265 to H264
Add your H.265/HEVC video
For a quick online conversion, upload one video encoded with H.265/HEVC. In UniConverter Desktop, add one or multiple local videos when you need larger-file processing, repeated jobs, or batch conversion.
Choose H.264/AVC as the output
Select H264 as the output option in the online converter. In UniConverter Desktop, choose an H.264/AVC output profile and adjust available settings such as resolution, bitrate, frame rate, or container when your workflow requires more control.
Convert and save the H.264 video
Start the conversion and save the H.264/AVC-encoded result. In UniConverter Desktop, process multiple local videos in one queue and save the converted files to your chosen output folder.
H265 vs H264: HEVC and AVC Compared
H.265 (HEVC) and H.264 (AVC) are video compression codecs, not container formats like MP4 or MOV. A video can stay in the same container while its video codec changes from H.265 to H.264.

Why Use UniConverter to Convert H265 to H264
Free Online H265 to H264 Conversion
Convert a single H.265/HEVC video to H.264/AVC in your browser with no signup or login. Use the online option for a quick one-off task and switch to Desktop when the job becomes larger or repeatable.
HEVC to AVC Codec Conversion
H.265 is also known as HEVC, while H.264 is also known as AVC. UniConverter lets you move from the newer HEVC codec to the more widely compatible AVC codec without confusing the codec with the MP4, MOV, or MKV container that may hold the video.
Broader Playback Compatibility
H.264/AVC is widely supported across media players, editors, devices, and publishing workflows. Convert from H.265 when the original HEVC video does not play, edit, or upload reliably in the destination you need.
GPU-Accelerated Desktop Conversion
Use UniConverter Desktop for larger local videos and repeated conversion jobs. GPU acceleration can speed up supported conversion workflows by up to 130× compared with standard processing.
Batch Convert Multiple H265 Videos
Add multiple H.265/HEVC videos to one Desktop queue and convert them to H.264/AVC with consistent output settings. This is better suited to folders, long recordings, and repeated workflows than a one-off browser conversion.
Flexible Output Settings and 1000+ Formats
Beyond H265 to H264 conversion, UniConverter supports 1000+ video, audio, and image formats. On Desktop, you can also review available output options such as codec, resolution, bitrate, and frame rate to fit the target device or workflow.
