変換は DOC と HTML の両方を表現できるすべての情報を保持します。HTML フォーマットがサポートしないフォーマット特有の機能 (例えば、ラスター出力のベクトルデータ、プレーンテキスト出力の公式) はラスター化またはストリップされます。結果ページのフォーマット特有の注意を参照してください。
Can I convert many DOC files to HTML at once?
+
Yes — drop multiple DOC 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.
Does the DOC to HTML converter work on phones / tablets?
+
Yes — the UI is responsive and the conversion pipeline runs server-side, so mobile devices upload-then-download just like desktops. iOS and Android browser file pickers (camera roll, Files app) work end-to-end.
Which browsers does the DOC to HTML converter support?
+
Chrome, Firefox, Safari (15+), Edge, and Opera. The converter uses standard `<input type="file">` upload — no WebAssembly or PWA dependencies — so even older browsers work.
Are my DOC files kept private?
+
Yes — uploaded DOC files are processed in isolated workers and deleted within minutes. We never view, retain, or share content. See /privacy/ for the data-retention window.
What if the HTML download doesn't start automatically?
+
Disable any pop-up blocker, then click the download button manually. The result link stays active for 24 hours, so if your network fails mid-download, you can re-trigger from the result page without re-uploading the DOC.
How long does DOC to HTML conversion take?
+
Typically seconds for small files, a minute or two for files near the size cap. Server-side pipeline runs on dedicated workers — your laptop CPU isn't the bottleneck.
Do I need to install software to convert DOC to HTML?
+
No — the converter runs entirely in your browser plus our servers. No desktop install, no plugin, no extension. Just upload, wait, download.
Can I convert DOC to HTML without an account?
+
Yes for one-off conversions. Sign up free for batch history, server-side file storage, and higher conversion limits. Premium adds parallel workers, bigger file caps, and no ads.
