When GIF to PNG turns GIF into PNG
A GIF logo looks rough because GIF only has 256 colors. PNG can hold a clean still image and transparency.
What GIF to PNG changes in the picture
One frame is saved as PNG. The animation is not kept. The file is not uploaded.
If you needed the moving GIF, do not use this. If you needed a photo, start from the original, not from the GIF.
When GIF to PNG is the right page
GIF to PNG sits on this site because GIF and PNG are not interchangeable, even when they look similar in a file list. A GIF logo looks rough because GIF only has 256 colors. PNG can hold a clean still image and transparency. Forums, stickers, and old tools still ask for GIF. Logos with few colors survive. Use PNG when a logo must stay crisp or when the background must stay transparent.

What you give up by leaving GIF
GIF is for simple motion and flat color. It only has 256 colors, so photographs look blotchy. Converting a PNG or photo to GIF posterizes the color. A still export drops animation.
Keep the PNG or the original animation if motion matters.
What you gain, and do not gain, with PNG
The download has to be PNG, because that is the format the next step named. Use PNG when a logo must stay crisp or when the background must stay transparent. Text in a screenshot stays sharper than it does in a heavy JPG.
PNG does not rescue a photo that was already compressed as JPG.
A test that matches the real file
Start from the question the other software asked. If it asked for PNG, GIF to PNG is the matching page. If it asked for something else, switch tools instead of hoping a similar extension will pass. A GIF logo looks rough because GIF only has 256 colors. PNG can hold a clean still image and transparency. One frame is saved as PNG. The animation is not kept. The file is not uploaded. The limit is the part people skip, and it is the part that decides whether the download is usable. If you needed the moving GIF, do not use this. If you needed a photo, start from the original, not from the GIF. The file stays in your browser and is not uploaded. The limit is 100 MB. Keep the original until the download has been opened in the program that will use it. Check three things in the download: it opens, the GIF material you cared about is still there, and the file size or the layout is what the form described. A new extension alone is not those three things. If a portal, a teacher, or a client rejects the file, send them the original GIF as well when you are allowed to. GIF to PNG is a convenience copy. It is not a new master. Photos fail uploads for three separate reasons: the format name, the pixel size, and the kilobyte size. GIF to PNG only does the GIF to PNG step. If the form also prints a pixel size or a 20 KB or 50 KB cap, do that step with the matching tool, starting from the original each time. A second lossy save will not recover detail.
Here is the decision for GIF to PNG. You start with GIF and you stop when a real program accepts PNG. A simple icon can stay small and widely supported. Photographs are usually much larger as PNG than as JPG, with little visual gain. If those two sentences describe a tradeoff you do not want, do not convert. Renaming the extension by hand will not do this job. Running the tool twice on its own output will not do it either.
If you needed the moving GIF, do not use this. If you needed a photo, start from the original, not from the GIF.
A related step, if you still need one, is PNG to GIF.
Other jobs start from the homepage, where each tool is named for the conversion it actually does.
