  5. PNG - Wikipedia

    en.wikipedia.org/wiki/PNG

    Poor compression increases the PNG file size but does not affect the image quality or compatibility of the file with other programs. When the color depth of a truecolor image is reduced to an 8-bit palette (as in GIF), the resulting image data is typically much smaller. Thus a truecolor PNG is typically larger than a color-reduced GIF, although ...

  6. Raster graphics - Wikipedia

    en.wikipedia.org/wiki/Raster_graphics

    Each raster grid has a specified pixel format, the data type for each number. Common pixel formats are binary , gray-scale , palettized , and full-color , where color depth [ 4 ] determines the fidelity of the colors represented, and color space determines the range of color coverage (which is often less than the full range of human color vision ).

  7. Image file format - Wikipedia

    en.wikipedia.org/wiki/Image_file_format

    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 palettes with a single transparent color. Compared to JPEG, PNG excels when the image has large ...

    The alternative Super series, denoted SnR, nR Plus or nR+, has an aspect ratio of 3∶2 (or as close as possible) and thus provides a better fit for standard 135 film (35 mm) at sizes of 8 inches or above. 5R is twice the size of a 2R print, 6R twice the size of a 4R print and S8R twice the size of 6R. 4D/6D is a newer size for most consumer ...

    optipng -o7 file.png advdef -z4 file.png pngout /ks file.png deflopt file.png Each of these utilities uses a different, more sophisticated "deflate" compression method variant on the PNG and generally produces a smaller file when run after the other tools. If the smallest result matters, try some experimenting to see what produces the best result.
