No re-upload neededThese tools accept .PNG - your file is handed over directly.
No. Everything runs in your browser - your file never leaves your device. How this is verifiable
A GIF stores only 256 colours per frame and knows transparency only as a hard on-or-off. APNG (animated PNG) lifts both limits: full 24-bit colour and a soft alpha channel with 256 levels of transparency. An animation that looks grainy as a GIF or frays at soft edges looks markedly cleaner as an APNG - and plays on its own and on a loop in every modern browser.
The tool decodes every single frame of the GIF along with its display duration and its transparency, assembles the frames pixel-accurately and encodes an APNG from them. The frame order, the per-frame delays and the endless loop are preserved. Because the source GIF only had 256 colours per frame anyway, this step is lossless - no artefacts are added.
The whole conversion runs strictly locally in your browser - the GIF is not uploaded and no library is loaded from a foreign server. The APNG file carries the .png extension and is a valid PNG; programs without APNG support simply show the first frame.
A clever detail of APNG: programs that do not know it simply show the first frame as a normal PNG - so the animation never breaks into a broken image. The price of the better colours and the soft transparency is size: an APNG is usually noticeably larger than the GIF, because every full frame is stored losslessly.

Limitations: The frame sequence, the per-frame delays and the endless loop are preserved; because GIF is limited to 256 colours, converting to the more colourful APNG is lossless. Static GIFs become a single-frame APNG. For memory reasons at most 1000 frames and 100 MB per file are allowed.
No. The conversion runs entirely in the browser - even in airplane mode.
Yes. All frames, their delays and the endless loop are carried over.
APNG is an extension of PNG. The file is a valid PNG; browsers with APNG support play the animation, others show the first frame.
Full colour instead of 256 per frame, and soft transparency instead of hard on-off edges.
