Extract text from LearnHub videos and archives (LH)
To convert LH LearnHub files to another format, you need Lhaplus or other Compressed software.
To convert other file formats to the "Video or Archive File" file type, you need software like Lhaplus or a similar tool.
The .lh file extension serves multiple, distinct purposes depending on its origin. Most frequently, it functions as an educational lecture video file for the LearnHub PH platform. In this scenario, the file is often an MP4 video container that has been renamed or slightly modified to associate directly with the LearnHub application. Alternatively, .lh represents a compressed archive file utilizing the older LHA or LZH compression formats. Finally, a smaller percentage of .lh files act as compressed game archives or level data files for Nintendo consoles, such as New Super Mario Bros. U and Nintendo 64.
To open these files, users typically need specific software. LearnHub videos require the official platform player or a versatile media tool like VLC Media Player. For archives, utilities like 7-Zip or Lhaplus are necessary, as modern operating systems lack native support for LHA compression. Nintendo game files usually require specialized emulator tools or community-developed level editors.
Working with .lh files presents several real-world disadvantages. If it is a LearnHub video, the file might be locked behind an ecosystem, making it difficult to view offline on standard media players or mobile devices. LHA archives rely on an obsolete compression algorithm from the 1990s that many modern extraction tools fail to parse correctly. Nintendo game archives are highly proprietary, closed-source formats designed specifically for console hardware, rendering them completely unreadable without niche reverse-engineering tools.
Users frequently need to convert .lh files into standard, accessible formats. LearnHub videos should be converted or renamed to standard MP4 or MKV files to restore universal playback compatibility. Legacy .lh archives should be extracted and re-compressed into modern ZIP or 7Z formats to ensure long-term data preservation and seamless support across Windows and macOS.
Because this file extension is shared among proprietary educational platforms, archaic compression algorithms, and closed console ecosystems, it is difficult for standard online tools to open or convert it. Often, only the original software can properly read or export the data. If our analysis detects a supported underlying or embedded format, viewing or conversion may still be possible.
Convert.Guru analyzes your LH file, detects the exact format, and lets you read the text inside.
Users also converted AUDIO, MP0, NVF, LS and PSI files.
If you want to convert LH file to LS, PSI, CSV, JSON, XML, YAML, YML, TOML, INI, CFG, CONF or DAT, you can use Lhaplus or similar software from the "Video Storage or Data Compression" category. In the File menu, look for Save As… or Export….
To convert DBF, XML, SQLITE, XLSX, SQL, TSV, ACCDB, YAML, MDB, CSV, ODS or JSON files to LH, try Lhaplus or another comparable tool in the "Video Storage or Data Compression" category.
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 LH converter.
