DOC to DOCX Transformation FAQ

How do I convert DOC to DOCX while keeping all my formatting?
+
Upload the DOC file and the converter maps every paragraph style, heading level, font, and inline run (bold/italic/underline) onto the equivalent DOCX construct. Where DOC and DOCX share a styling model (DOCX↔ODT↔DOC) fidelity is near-perfect; converting to a flat format like TXT deliberately drops styling and keeps only the text.
Named styles (Heading 1, Body Text, Quote) are remapped to the DOCX style table so they stay editable and consistent after conversion. Direct character formatting (a manually-bolded word) is preserved as inline DOCX runs. Converting into TXT or Markdown flattens named styles into plain text or Markdown markers respectively.
Yes — table grids, merged cells, column widths, and per-cell alignment carry from DOC into DOCX when the DOCX format supports tables (DOC, DOCX, ODT, RTF, HTML). Converting to TXT renders tables as tab-separated text because plain text has no table model.
Tracked changes and comments are preserved when both DOC and DOCX support revision metadata (DOCX, ODT, DOC). If you convert to a format without a revision model (TXT, RTF in basic mode), accept or reject changes in your editor first — otherwise the converter flattens them into the final text so nothing is silently lost.
Font family, size, color, and spacing are written into the DOCX file by name. The exact rendering depends on whether the reader has that font installed; for guaranteed identical appearance across machines, convert to PDF instead. For an editable DOCX like DOCX or ODT, the font references travel with the file and resolve on open.
Yes — that is the point of a DOCX target like DOC, DOCX, ODT, or RTF: the output opens as a fully editable document in Word, LibreOffice, or Google Docs with text, styles, and tables intact. (A PDF target would instead lock the layout; choose DOCX here precisely because you want to keep editing.)
Headers, footers, page numbers, and section breaks carry into DOCX when the format is page-aware (DOCX, ODT, DOC, RTF). Flat targets (TXT, Markdown) have no page concept, so running headers and page numbers are dropped — the body text is preserved in reading order.
Inline and floating images embedded in the DOC are extracted and re-embedded in the DOCX at their original resolution and anchor position, for every DOCX format that stores images (DOCX, ODT, DOC, RTF, HTML). Converting to plain TXT drops images because text files cannot carry binary image data.
Yes — drop multiple DOC files into the upload zone and they convert in parallel, each producing its own DOCX download bundled as a ZIP. Premium runs more parallel workers and lifts the per-file size cap, so a large batch of long documents finishes in a fraction of the time.
Yes — uploaded DOC files are processed in isolated workers and deleted within minutes. We never open, read, store, or share document contents. The full retention window is documented at /privacy/.
Bulleted and numbered lists, including multi-level outlines and restart-at-1 numbering, are mapped onto the DOCX list model (DOCX, ODT, DOC, RTF, HTML). Markdown targets convert them to `-`/`1.` markers; TXT targets keep the visible bullet characters and indentation as plain text.
Yes — DOCX is the universal interchange format both Google Docs and Word import natively, and DOC, ODT, and RTF import cleanly too. Convert your DOC to DOCX here, then drag the file straight into Docs or open it in Word; styles, tables, and images come through ready to edit.
