Convert Document with LibreOffice API

What it does

LibreOffice Convert turns an uploaded office document into another file format. Send a binary file in the file field, and set target_format when you need something other than the default pdf. The response is the converted file itself as binary output.

Use it when you need to normalize documents before sharing, store generated files in a different format, or convert incoming office attachments into something your pipeline can process. The API is focused on a single job: file-to-file conversion using LibreOffice’s document handling.

Because the output is a binary file, it fits cleanly into workflows that download, forward, or persist the converted document. Typical uses include turning spreadsheets into PDFs for review, exporting text from office files, or converting documents into another office format for compatibility with downstream systems.

If your application accepts uploaded office documents and needs a predictable conversion step, LibreOffice Convert gives you a direct way to transform the file without exposing LibreOffice itself in your stack.
