Convert OpenDocument HTML templates (OTH) online for free
The converter easily converts your OTH templates to various formats - free and online. No LibreOffice or other Web software needed.
To convert other file formats to the "OpenDocument HTML Template" file type, you need software like LibreOffice or a similar tool.
The .OTH file extension primarily represents an OpenDocument HTML Template, used by open-source software like LibreOffice Writer to create standardized web document structures. Under the hood, these are compressed ZIP archives containing XML data, stylesheets, and embedded media, governed by the OASIS OpenDocument Format. A secondary but common use is the Origin Graph Theme file, an XML based settings file utilized by OriginLab data analysis software to store visual formatting presets for scientific graphs.
You usually need to convert .OTH files because they are highly software-specific and lack broad compatibility. An OpenDocument HTML Template requires a full Office suite to open and cannot be natively displayed by a standard web browser despite its name. Similarly, Origin Graph Themes are useless without an expensive, proprietary Origin software license. Sharing these specific template files often leads to frustrating compatibility errors or complete formatting loss for the recipient.
For web use, convert your OpenDocument .OTH to standard HTML or PDF to ensure the document displays flawlessly on any device. If you just need to extract the text data, convert to TXT or DOCX. For Origin theme files, converting to raw XML makes the formatting parameters readable in any code editor.
