No. Everything runs in your browser - your file never leaves your device. How this is verifiable
GIF files are convenient but inefficient - every frame is stored completely fresh, without the compression tricks of a real video format. An old meme GIF, a screen-recording export or an animated graphic often compresses to a fraction of the size as MP4, at equal or better picture quality - and MP4 plays natively on virtually any device without the browser having to run the GIF animation separately.
Important and honest: every GIF frame is re-encoded as its own video frame, held for exactly the delay the GIF itself specifies for that frame - so playback speed is preserved exactly. This needs a hardware video encoder in your browser; without one, the tool honestly reports that instead of producing an unusable output.
Everything runs locally in the browser with mediabunny (MPL-2.0, self-hosted, no third-party CDN) on the browser's native WebCodecs API. Your file is not uploaded.

Limitations: Without a hardware video encoder in your browser, the tool stops with a clear message instead of shipping a risky file. The same intake limits as the GIF-optimize tool apply to the import: at most 1000 individual frames, 100 MB per file. Because GIF is inherently silent, the resulting MP4 carries no audio track either.
No. The conversion happens entirely in your browser tab's own memory.
Yes, every GIF frame is encoded as a video frame with exactly the GIF's own delay.
No, GIF itself has no audio track, so the MP4 has none either.
A real video codec exploits similarity between consecutive frames - GIF, by contrast, stores each frame practically from scratch.
Yes, for that there is the sibling tool "GIF to WebM".
