PNGs support either 24-bit or 8-bit colors. The higher the bit support, the more available colors there are for that PNG — and the larger the file size. If your website has a simple logo that is a 24-bit PNG, that file is taking up unnecessary space and slowing down your page ...
No, I haven't found a way to save a png larger than 8 bits. Unless they gave you a 16-bit "png" and you put save as copy. Otherwise I have not found - 13589968
Images contain redundant information.Lossless compressionremoves that redundant data, but it also tells the computer how much of the data was redundant and how to rebuild the image. The file size is reduced to save space, but the entire file can also be reconstructed from the compressed one. I...
The 2nd scaled down image actually ended up having a larger file size than the first one. I saved both of them using the largest file size option, but the scaled down one should still be smaller. Why has this happened and how can I stop it from happening? I'...
The other thing to note, however, is that the elements we need are defined aspng_uint_16, i.e., as 16-bit (or larger) unsigned integers. Thatsuggests that the color values we get back may depend on the bit depth of the image, which is indeed the case. In fact, this is true re...

HalftoneUses evenly spaced dots of varying diameter to produce apparent shades of gray. The darker the shade at a particular point in the image, the larger the corresponding dot in the halftone. Varying the size and density of the dots creates the illusion of variations of gray or co...
If the target dimensions are larger than the original dimensions, the image willnotbe scaled up. Scaling up is prevented in order to protect the quality of your images. Converting images You can use the API to convert your images to your desired image type. Tinify currently supports converting...
but libpng currently assumes that its error-handling routine will never return. This rather drastically limits the options for alternatives--basically, one can uselongjmp()orexit(), which amounts to an even largergotostatement. [104] Here, as inChapter 14, “Reading PNG Images Progressively”,...
