How to open .UVH files on iOS
To open .UVH files on iOS, iOS typically won’t have common native support for specialized DECE/UltraViolet segment files; if it won’t preview in Files, transfer it to a desktop system or open it within the specific app/workflow that provided it.

Common issues
The .uvh file won’t play in common media players
.uvh is commonly used as a DECE/UltraViolet HD streaming segment type (video/vnd.dece.hd), which many consumer players don’t support directly or don’t treat as a standalone video file.
- Look for companion streaming files from the same source (for example, a manifest/playlist) and open that instead of the .uvh segment.
- Try opening/importing the file in the same software/workflow that created or downloaded it.
- If you must make it playable elsewhere, use a trusted conversion/packaging workflow from the original toolchain rather than renaming the extension.
The file opens in the wrong app (or shows as an unknown file type)
Your system may not have an extension→MIME mapping or default app association for .uvh. On Linux desktops this typically depends on shared-mime-info mappings and your chosen default applications.
- Manually choose the app: Open with… and select the correct tool for the workflow that uses the file.
- On Linux, verify the system’s MIME handling/associations and set a default application for the detected MIME type (often video/vnd.dece.hd in DECE contexts).
You only received a single .uvh file and nothing else works
In streaming workflows, a single segment may be incomplete without the rest of the package (additional segments, manifest/playlist, metadata).
- Ask the sender/source for the complete set of files required by the stream (not just one .uvh).
- Re-download or re-export the content from the original source to ensure all related assets are included.
Renaming .uvh to .mp4 doesn’t help
Changing the filename extension doesn’t convert the underlying format, and players will still fail if the internal structure isn’t MP4 (or if the file is only a segment).
- Restore the original extension and handle it as a DECE/UltraViolet HD video segment.
- Convert/export using an appropriate tool in the original workflow, if conversion is necessary.
Security note
.uvh files are video data, but media parsers can have vulnerabilities; only open .uvh files from sources you trust, especially if your player or toolchain is outdated.
