Frequently Asked Questions

How does this converter work?It runs a WebAssembly in your browser. Your file never leaves your device. If the advanced engine can’t start, a text-only fallback recovers the document’s text.
Is my file uploaded anywhere?No. Conversion happens locally in your browser (client-side). We don’t send your documents to a server.
Which formats are supported?Input: .odt, .fodt, and most .ott templates. Output: .docx (Microsoft Word).
Why don’t some images show after conversion?The tool embeds images and repairs DOCX content types/relationships, but certain ODF drawing objects, linked images, or uncommon formats may not render in Word. Embed images and use PNG/JPEG for best results.
What features might change or be lost?Complex page styles, custom headers/footers, frames, text boxes, macros, fields, tracked changes, some charts/diagrams, and some equations may not fully translate. The fallback preserves text only.
Can it convert password-protected or encrypted files?No. Encrypted/password-protected ODF files are not supported. Remove protection before converting.
Will it recover corrupted or truncated files?The advanced engine may fail on damaged files. The fallback attempts basic text recovery if a readable content.xml exists. Images/formatting are not recovered in fallback mode.
How big of a file can I convert?It depends on your device and browser memory. Many machines handle 1–50 MB documents. Very large/image-heavy files may run out of memory.
Which browsers are supported?Current Chrome, Edge, Firefox, and Safari. Module Workers and WebAssembly must be enabled (default in modern browsers). Desktop performs better for large files.
Why does the first conversion take longer?The WebAssembly engine is fetched and initialized on first use. Conversions are faster after the first run in the same tab.
Is there any cost or tracking?Conversion runs locally and does not require an account. The tool does not transmit your file contents for processing.
Who is the publisher of the converted DOCX?The DOCX is stamped with SimpleToolsHub in the metadata as creator/last modified by. You can edit these properties in Word (File → Info → Properties).
Tips for best resultsEmbed images (don’t link), prefer PNG/JPEG, use standard fonts, and export a clean ODT from LibreOffice. If output looks off, simplify nested frames/styles and re-convert.
