No. Everything runs in your browser - your file never leaves your device. How this is verifiable
APNG (animated PNG) offers full colour and soft transparency, but it is not played everywhere - some older programs, previews and chat services show only the first frame. The GIF is the lowest common denominator here: for decades it has played automatically and on a loop practically everywhere. This step makes an APNG animation universally shareable.
The tool decodes every single frame of the APNG, correctly resolves its offset, blend and dispose rules into one complete frame and encodes a GIF from them. The frame order, the per-frame delays and the endless loop are preserved. Because GIF only knows 256 colours per frame, each frame is reduced to its own 256-colour palette; fully transparent areas are kept as one-bit transparency.
The conversion runs strictly locally in your browser - the APNG is not uploaded and no library is loaded from a foreign server. Because GIF is coarser in colour, this is the lossy part of the journey; a static PNG honestly becomes a single-frame GIF.

Limitations: The frame sequence, the per-frame delays and the endless loop are preserved. GIF uses only 256 colours per frame, so gradients look coarser than in the APNG; semi-transparent pixels become opaque, fully transparent ones stay transparent. A static PNG becomes a single-frame GIF. At most 1000 frames and 100 MB per file.
No. The conversion runs entirely in the browser - even in airplane mode.
Yes. All frames, their delays and the endless loop are carried over.
GIF stores only 256 colours per frame. Fine gradients become coarser as a result - that is down to the format, not the conversion.
GIF only knows one-bit transparency. Fully transparent areas stay transparent, semi-transparent ones become opaque.
