Although PNG is a lossless format, PNG encoders can preprocess image data in a lossy fashion to improve PNG compression. For example, quantizing a truecolor PNG to 256 colors allows the indexed color type to be used for a likely reduction in file size. [91]
In Windows, all executables that display an icon to the user, on the desktop, in the Start Menu, or in file Explorer, must carry the icon in ICO format. The CUR file format is an almost identical image file format for non-animated cursors in Microsoft Windows. The only differences between these two file formats are the bytes used to identify ...

Specifying a size does not just change the apparent image size using HTML; it actually generates a resized version of the image on the fly and links to it appropriately. This happens whether or not you specify the size in conjunction with "thumb". This means the server does all the work of changing the image size, not the web browser of the user.
As computer icons can be used in different sizes, icon design involves creating master artwork usually for the biggest size used and producing smaller sizes from it. It is desirable to comply with overall style of the icon set, using the same color palette, perspective and renderings for all icons.
Animated PNG images with a frame size larger than 12.5 million pixels cannot currently be displayed in thumbnail form in Wikipedia articles, a significantly lower limit than the GIF format, and is not fully supported on all browsers. A JPEG or other compressed image format can be much smaller than a comparable GIF or PNG format file. When there ...
For example, most image files store information about image format, size, resolution and color space, and optionally authoring information such as who made the image, when and where it was made, what camera model and photographic settings were used , and so on. Such metadata may be used by software reading or interpreting the file during the ...
