HTMLZ → MD

Yes. The free tier accepts files up to 100 MB without registration, email capture or watermarks. Paid plans raise the size cap, enable batch conversions and provide a REST API for automation, but nothing on the free tier is quality-limited — the output is exactly the same as on any paid plan.

Yes when the source HTMLZ tags chapter starts semantically (H1 / section boundaries). Each chapter becomes a new section in the MD with a page break before it. If the HTMLZ uses only visual cues like larger font sizes, enable "detect chapters heuristically" in Advanced so we still produce clean breaks.

Uploads run over HTTPS, files are processed in isolated containers, and both the source HTMLZ and the MD output are auto-deleted within two hours. No account is required, file contents are never logged, and KaijuConverter does not use uploads for AI training. The paid plan adds a signable data-processing agreement for regulated workflows.

Yes. The cover from the HTMLZ becomes the first page of the MD (or is moved to metadata depending on document conventions). Inline images re-embed at their source resolution; you can toggle "optimise images" in Advanced to shrink the MD file size.

Most files finish in well under a minute. Small images and documents are typically ready in a few seconds; large video or audio files scale roughly with duration. Upload speed from your network is usually the dominant factor, not server time.

Yes. We produce a clean MD with paragraph and heading styles mapped to standard document styles. Open it in Word, LibreOffice or Google Docs and you can edit, comment and track changes just like any native document.
