Frequently Asked Questions

ODT (OpenDocument Text) is an open standard format used by LibreOffice Writer, OpenOffice Writer, and other compatible applications. It's an ISO-standardized document format ensuring long-term accessibility.

No. All processing happens locally in your browser. Your files never leave your device. This ensures complete privacy and works even offline.

Text, paragraphs, basic formatting (bold, italic, underline), headings, and images are preserved. Complex features like SmartArt or advanced Word features may be simplified.

Standard fonts are preserved. Custom or proprietary Microsoft fonts may be substituted with similar alternatives in LibreOffice. Paragraph styles and headings are mapped to ODT equivalents.

Embedded images (PNG, JPG, GIF) are copied to the ODT file. Linked images or complex graphics may require re-embedding. Vector formats like EMF/WMF may not display correctly.

Simple tables with text and basic formatting convert well. Complex nested tables, merged cells, or tables with advanced styling may need manual adjustment in LibreOffice.

ODT is an open standard ensuring long-term accessibility, free from vendor lock-in, and works with free software like LibreOffice. It's ideal for archival, cross-platform collaboration, and avoiding proprietary formats.

Yes. LibreOffice can save ODT files as DOCX, or use our ODT to DOCX converter. However, some formatting may change with each conversion cycle.

ODT files are typically similar in size to DOCX, sometimes smaller due to efficient compression. Image-heavy documents may be larger depending on original image formats.

Advanced Word features like macros, ActiveX controls, custom XML, tracked changes, and complex fields are not supported. Comments may be lost. Review the output in LibreOffice and adjust as needed.
