What software writes ODT files?

ODT (OpenDocument Text) is the native word-processing format for LibreOffice Writer and Apache OpenOffice Writer, standardized as ISO/IEC 26300 since 2006. The format is a ZIP archive containing content.xml (the document body), styles.xml (paragraph and character styles), meta.xml (author, title, dates), and embedded image / object subfolders. It's the mandated document format for German federal agencies (BSI 2018 directive), French government open standards (RGI), and many Brazilian and Indian public-sector institutions where vendor lock-in to Microsoft Office is explicitly prohibited.

Converting ODT to JPG rasterizes each page of the document into one JPG at the document's page size and DPI - typically A4 at 150 or 300 DPI, producing 1240x1754 or 2480x3508 pixel output respectively. Embedded images, OLE objects (charts, equations), footnotes, headers, and tracked changes all render as they would in Writer's print preview. Each page becomes a separate file numbered sequentially. The conversion runs on a headless LibreOffice instance, so output matches what you'd see in Writer's native PDF export.

Open-source-mandated government workflows, academic theses written in LibreOffice, and Linux desktop users sharing CV / report PDFs are the typical audience. For editable handoff to Microsoft Word use Writer's File > Save As > .docx, which round-trips most formatting correctly. For visual-only sharing to recipients without any office suite, JPG-per-page is the universal solution - works in any image viewer, email client, or mobile gallery. Long documents (200+ pages) can take minutes to convert; consider PDF-to-JPG via Writer's PDF export as a faster alternative.

Reasons to convert ODT to JPG usually come down to compatibility, file-size, or specific feature requirements. Common situations:

• An app or platform only accepts JPG uploads.
• You need a feature unique to JPG (e.g. transparency, vector scaling, animation, multi-page pages, etc.) that ODT doesn't provide.
• You're optimising file size — modern formats often produce smaller files than the older format you started with.
• You need a single archival format across a project so files behave consistently in the same viewer.

1. Open the ODT → JPG tool on jpg.now.
2. Drag your ODT file onto the drop zone, or click Select files. You can drop a whole folder of files at once.
3. The output is fixed to JPG. If the format supports extra options (page size, transparency background, quality, EXIF stripping), tweak them in the right-hand panel.
4. Click Convert. The job runs on our server and finishes in a few seconds for typical photos.
5. Download the result. Files stay in storage for 24 hours and are then permanently deleted.

The entire flow is free for the first 10 jobs per day with no signup required. A free account doubles that quota; a premium plan removes the limit entirely.

• Use LibreOffice Writer's File > Export As Images for native high-quality export when you have the desktop app installed.
• Documents with embedded LibreOffice Math equations render correctly because LibreOffice handles the OLE objects natively - external converters often miss them.
• Tracked changes and comments export visibly by default - accept or reject them in Writer first if you want a clean output.
• ODT is a ZIP archive - rename to .zip and extract to recover embedded images byte-for-byte from the Pictures/ subfolder.
• For corporate environments mandating ODF, save final deliverables as ODT and provide JPG previews for non-LibreOffice recipients.
