Does the PNG keep my GIF transparency?
Yes. Any transparency in the GIF is carried into the PNG, and because PNG uses a full alpha channel rather than the GIF's on-or-off transparency, the edges often look cleaner than they did before.

For a static graphic, PNG is almost always a better home than GIF. Both are lossless and both support transparency, but PNG does each job better. Where a GIF is capped at 256 colours and can leave visible banding on gradients, PNG handles the full colour range smoothly. And where a GIF only offers on-or-off transparency that often shows a jagged fringe, PNG stores a proper alpha channel with soft, clean edges. Converting is the natural move when you want to keep a graphic crisp and editable.
The tool reads each GIF and writes a PNG, carrying over whatever transparency the GIF held so the image still drops neatly onto any background. There is no quality setting because nothing is being compressed away; the PNG is a faithful, lossless copy. This makes it a sound choice for logos, icons, diagrams and any flat-colour artwork that you plan to reuse or place over other content.
The difference comes down to two ceilings GIF was built around, and PNG removes both. The first is colour: a GIF can show at most 256 distinct shades, and to suggest anything beyond that it scatters dithering dots that become obvious on a gradient or a soft shadow, while PNG simply stores the real colours. The second is transparency, where a GIF allows a pixel to be only fully on or fully off, leaving a stair-stepped fringe, while PNG blends edges smoothly against any background. File size can land on either side depending on the picture, but for most static images the cleaner PNG is the one worth keeping.
PNG is a single still image, so an animated GIF is converted using its first frame; the animation itself is not preserved. When you specifically need a smaller photographic file and transparency does not matter, GIF to JPG is the lighter-weight alternative. Since a GIF is already limited to 256 colours, you can also pass the PNG through Compress Image afterward to trim it without any visible loss.
Convert a single GIF or a whole set in one pass. If the PNG then needs to be lighter for a web page, PNG to WebP compresses it while holding on to the transparency.
Add one file or a whole set in a single go.
Every GIF becomes a lossless PNG, keeping whatever transparency it had. There is no quality choice to make.
One file on its own, or a ZIP when you convert several.
Yes. Any transparency in the GIF is carried into the PNG, and because PNG uses a full alpha channel rather than the GIF's on-or-off transparency, the edges often look cleaner than they did before.
For a still graphic, generally yes. PNG handles the full colour range without the banding a 256-colour GIF can show, and its transparency is smoother. Both are lossless, so you keep full quality either way, but PNG does the job more cleanly.
A PNG holds one still image, so the conversion uses the first frame of the animation and drops the rest. There is no quality loss in that frame, but the motion is not preserved.
PNG is lossless, so there is nothing to trade off. The image is copied exactly rather than compressed, which is why the tool simply converts without asking for a quality level.
It can go either way. A simple GIF with few colours may grow a little as a PNG, while a more detailed one often shrinks. Either way the PNG is lossless and cleaner, and you can pass it through Compress Image afterward if the size needs trimming.
