WHY CONVERT
Why convert DOCX to HTML
02
Broader cross-platform support
HTML is accepted by a wider range of document readers and collaboration tools than DOCX. The conversion removes a recurring compatibility friction without changing what the file actually contains.
03
Portable, predictable file format
HTML is well documented and decodable by long-lived tooling, which matters for archives, deliverables, and any file that needs to outlive the software that created it.

— FAQ
Frequently asked.
Is DOCX to HTML conversion free?
Yes. LocalConvert is completely free, with no signup and no per-file or per-day limits.
Do my files get uploaded anywhere?
No. DOCX to HTML conversion happens entirely inside your browser using WebAssembly — your file never leaves your device.
What's the maximum file size?
There's no fixed cap — the practical limit is your device's available memory. Very large files may take longer or fail on low-RAM devices.
Does it work offline?
Yes — once the page has loaded, DOCX to HTML conversion works without an internet connection. Re-open the page once to cache it.
Will conversion preserve quality?
LocalConvert uses the industry-standard tools (FFmpeg, ImageMagick, Pandoc) — quality matches what professionals use on the command line. Lossy formats will still lose some quality on each re-encode.
