Upload your MOBI file using the picker above and the converter detects the source type and runs the MOBI → DOC pipeline. The result downloads automatically when conversion completes; no account needed for one-off conversions.
Is the MOBI to DOC converter free?
+
Yes — basic MOBI → DOC conversion is free with no registration. Premium adds higher per-file size limits, more parallel batch workers, and removes ads.
How big a MOBI file can I convert to DOC?
+
Free accounts: up to 100 MB per MOBI file. Premium: typically 1 GB per file, depending on the MOBI source type. Very large files are split into chunks server-side when the DOC format allows.
Will conversion change the content of my MOBI?
+
Conversion preserves all information that both MOBI and DOC can represent. Format-specific features that the DOC format doesn't support (e.g. vector data in raster output, formulas in plain-text output) are rasterized or stripped — see the format-specific notes on the result page.
MOBI ファイルを DOC に一度に変換できますか？
+
Yes — drop multiple MOBI files into the upload zone and they are queued in parallel. Premium has more parallel workers; on a 50-file batch this is the difference between minutes and seconds.
