What does the DOC to DOCX converter do?
+
It converts a DOC document into DOCX. Text, paragraph styles, tables, and embedded images are preserved as closely as the target format allows.
Will the formatting of my DOC survive the conversion to DOCX?
+
Headings, paragraph styles, tables, and embedded images carry across. Advanced layout (text boxes, complex columns, macros) may simplify when DOCX does not support the feature one-for-one.
Is the DOC to DOCX conversion reversible?
+
You can convert the DOCX back to DOC on this site. If either format involved is lossy, the round-trip is not bit-perfect even though it is visually or audibly close.
What output quality should I expect from DOC to DOCX?
+
Default settings target broadcast / web quality — visually identical to the source for most viewers. For archival use, pick the highest quality option in the converter settings.
Is there a file-size limit when converting DOC to DOCX?
+
Anonymous uploads are capped at a generous default; signed-in free accounts get a higher cap, and Pro accounts have no per-file limit. Browser memory is usually the practical constraint long before our server-side limits kick in.
Can I batch-convert several DOC files to DOCX at once?
+
Yes. Drop or pick multiple DOC files in one upload — the converter processes them in parallel and returns a ZIP of the DOCX results. There is no need to repeat the upload step per file.
What happens to my DOC files after the conversion?
+
Uploaded files and DOCX outputs are auto-deleted after a short retention window. We do not inspect, share, or train on user files. Direct download links are time-limited and tied to your session.
Can I edit the DOCX after converting from DOC?
+
Yes — DOCX opens in Word, Google Docs, LibreOffice, and most office suites. Text, formatting, and tables are editable.
Do I need to install software to convert DOC to DOCX?
+
No. The converter runs entirely in your browser plus our cloud — no plugin, no install, no admin rights. It works on Windows, macOS, Linux, ChromeOS, iOS, and Android.
Do I need an account to convert DOC to DOCX?
+
No. DOC to DOCX conversion is free and works without an account. Signing in unlocks higher file-size caps, batch history, and API access.
Is there an API for DOC to DOCX conversion?
+
Yes. Every conversion this site offers is also exposed via a JSON API — see /api/ for endpoints, authentication, and rate limits. DOC to DOCX is one of the supported pairs.
What if my DOC fails to convert to DOCX?
+
Failures are usually caused by corrupted source files or unsupported DOC variants. Re-export from the original app and try again; if it still fails, the contact page forwards the file to support so we can diagnose.
