Roadmap & Disclaimer

Scope notes on Office conversion, text editing, watermark removal, and more。 Runs locally—nothing uploaded.

Office interchange (Word / Excel / PPT)

Typical approaches: self-hosted converters (LibreOffice / OnlyOffice / commercial APIs) or in-browser WASM (evaluate bundle size, licensing, and output quality).
Suggested product stance: clearly label when high-fidelity conversion requires upload to a conversion service, plus privacy terms.

Bulk text edits / watermark removal

PDF text is usually drawing operators, not an editable document tree; "Word-like" edits typically need a professional PDF engine or manual cleanup.
Watermark removal cannot be guaranteed for arbitrary files; compliant scope is removing layers added via this site's tools, with clear restrictions in terms.
