Convert H264 files online for free
The converter easily converts your H264 file to various formats - free and online. No VLC or extra software needed.
The converter also works in reverse, so you can convert other Video formats to H264 with high quality output.
A .h264 file is typically a raw video elementary stream encoded using the H.264/MPEG-4 AVC standard. Unlike standard MP4 or MOV files, a raw .h264 file lacks a "container" format. This means the file contains pure video data but is missing critical metadata headers, timecodes, audio tracks, and indexing information required for smooth playback and seeking.
These files are most frequently generated by CCTV security systems (such as Dahua or Hikvision DVRs/NVRs) or as raw output from video encoding software like x264. Users frequently experience issues when trying to open these files: standard players like QuickTime or Windows Media Player will fail to recognize them, and professional editors like Adobe Premiere Pro cannot import them because they lack a timebase. Additionally, without container indexing, you cannot "fast forward" or "rewind" the video even if it does play in robust players like VLC media player.
To make the video usable, widely compatible, and editable, the raw stream must be converted (or "wrapped") into a standard container. For web use and general playback, convert to MP4. For archiving security footage without quality loss, MKV is an excellent target. If you need to edit the footage, converting to an intermediate format like MOV or AVI ensures your video editor can interpret the timing correctly. Convert.guru handles this encapsulation process, transforming raw data into viewable video instantly.

The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our H264 converter.
