No. Everything runs in your browser - your file never leaves your device. How this is verifiable
PNG is the right choice when your AVIF image has transparency or you need lossless edges - for logos, screenshots or graphics. PNG is supported by every program.
The AVIF is decoded locally with a self-hosted codec and exported as PNG; transparency is fully preserved. Nothing is uploaded.
Mind the difference in method: AVIF usually stores your image lossily, while PNG stores it losslessly with the Deflate algorithm. So the conversion cannot bring back the fine detail the AVIF encoder already discarded - it only freezes the current state pixel for pixel. That is exactly what you want when a logo, a chart or a screenshot needs further editing in a program that cannot handle AVIF, or when the soft alpha channel of an icon must be preserved without new compression loss.
A frequent trigger for this step is a downloaded graphic that comes as AVIF and simply refuses to appear in a presentation or office document. As PNG that obstacle disappears at once. If you have a moving AVIF, the tool honestly takes only the first full frame, because an ordinary PNG holds no sequence of several frames.

Limitations: PNG files are larger than AVIF, especially for photos. For small photo files, AVIF to JPG is a better fit. Animated AVIF is converted as the first frame.
Yes. PNG carries a full alpha channel with 256 levels, so soft edges and semi-transparent shadows from the AVIF survive exactly - nothing is flattened onto white.
No, everything runs locally in the browser.
No, no new loss is added: PNG takes over every pixel losslessly and exactly. Artefacts the AVIF encoder stamped into the image earlier stay frozen, though - PNG cannot compute them away. The result matches exactly what you see on screen.
