docsbox

docsbox is a standalone service that allows you convert office documents, like .docx and .pptx, into more useful filetypes like PDF, for viewing it in browser with PDF.js, or HTML for organizing full-text search of document content.
docsbox uses LibreOffice (via LibreOfficeKit) for document converting.

Settings (env)

Scaling

Within a single physical server, docsbox can be scaled by docker-compose:
