2. Help : How to reduce colors for saving a JPEG as PNG

   en.wikipedia.org/wiki/Help:How_to_reduce_colors...

   Sometimes, you find a drawing or similar image useful for a Wikipedia article, that was saved as a JPEG but should have been saved as a PNG.JPEG is good for images where the color changes fluidly throughout the image, like in a photograph, whereas PNG files are good for images with relatively few colors, such as a drawing of a flag, a chart, or a map; note that sometimes SVG is better.

   The PNG (Portable Network Graphics) file format was created as a free, open-source alternative to GIF. The PNG file format supports 8-bit (256 colors) paletted images (with optional transparency for all palette colors) and 24-bit truecolor (16 million colors) or 48-bit truecolor with and without alpha channel – while GIF supports only 8-bit ...

   JPEG XL is another, much improved, lossless or lossy format, that is unfortunately supported much less, developed to replace lossless formats like PNG. [57] JPEG XL is more than 50% smaller than JPEG, and that can happen while it's lossless, therefore making it even smaller than PNG. [58]

6. Image scaling - Wikipedia

   en.wikipedia.org/wiki/Image_scaling

   In the case of decreasing the pixel number (scaling down), this usually results in a visible quality loss. From the standpoint of digital signal processing, the scaling of raster graphics is a two-dimensional example of sample-rate conversion, the conversion of a discrete signal from a sampling rate (in this case, the local sampling rate) to ...

   When saving a JPEG, the graphics program will let you choose the compression level. Usually the values range from 0 to 100 where 100 is the best quality possible with very little compression applied. Some apps, notably Paint Shop Pro, reverse this scale with 0 as highest quality and 100 as the lowest quality. Don't mistake the 0 to 100 scale ...
