Convert apng to gif with sufficiant resolution and color depth

I want to convert some animated PNG (APNG) images to animated GIF. I can successfully convert with a utility I found on the web called apng2gif. Expertly named if I may say. The problem is it does not convert the images with sufficient color depth so the output is a little bit to pixelated and not so smooth relative to the original.

开发者_C百科Does anyone know of any other image converters that might convert APNG to GIF with more that 16 bit color depth?

The problem is not with the converter, but with GIF format itself:

http://en.wikipedia.org/wiki/Graphics_Interchange_Format

The format supports up to 8 bits per pixel thus allowing a single image to reference a palette of up to 256 distinct colors.

If you need the GIF to blend better with the background, click on Settings button in apng2gif and then choose the background color you want.
