No. Everything runs in your browser - your file never leaves your device. How this is verifiable
WOFF2 is built for the web and cannot be installed on your system directly. OTF is the classic desktop format for fonts with PostScript CFF outlines that Windows, macOS and design tools open natively. This conversion brings the font out of the web container back into an installable format - the counterpart to woff2-to-ttf for CFF-based fonts.
This tool decompresses the WOFF2 locally back to its sfnt tables. If the WOFF2 truly carries PostScript CFF outlines (the OTTO flavor baked into the font itself, independent of the file name), you get a real OTF; every glyph, kerning table and OpenType feature survives byte-for-byte, because only the container changes, never the letterforms.
Important for honesty: not every WOFF2 holds CFF outlines - many come from a TTF and carry TrueType outlines (glyf) instead. If your WOFF2 holds TrueType rather than PostScript, this tool rejects the conversion with a clear message instead of outputting a wrongly labelled file; use woff2-to-ttf for that case. This check runs on the actually unpacked font, not on the original file name.

Limitations: If the WOFF2 holds TrueType outlines (glyf) instead of PostScript CFF, the tool honestly rejects the conversion - use woff2-to-ttf for that case. No outline conversion between glyf and CFF happens. Only convert fonts you own or have a licence for.
No, everything runs locally in the browser - even in airplane mode.
Then the tool rejects it and states the reason; use woff2-to-ttf instead.
Yes. The conversion is lossless; the glyph count is verified after conversion.
Yes, you get an installable OTF for Windows and macOS.
