When a picture is saved uncompressed from paint. You should use PNG instead of BMP as it still retains the quality loss-less but compresses it.
BMP the file name extension for the Bitmap image file format.
BMP is a file format for storing pictures on a computer. It stands for bit-map.
BMP
BMP files tend to be very big, as they are not compressed.
The BMP file format, sometimes called bitmap or DIB file format (for device-independent bitmap), is an image file format used to store bitmap digital images, especially on Microsoft Windows and OS/2 operating systems. Many graphical user interfaces use bitmaps in their built-in graphics subsystems;[1] for example, the Microsoft Windows and OS/2 platforms' GDI subsystem, where the specific format used is the Windows and OS/2 bitmap file format, usually named with the file extension of .BMP or .DIB (source Wikipedia) or basic metabolic panel (BMP), a group of 8 tests used as a general screening tool. (You probably are looking for the latter lol)
Macs don't support bmp file format.
I have never heard of .bif before, apparently it is an archive format and .bmp is a bitmap image file.
Yes, along with TIF, JPG.
GIF or bitmap (bmp)
The image file format you are referring to is the BMP (Bitmap) format. BMP files are uncompressed raster images that can store a variety of color depths per pixel, including grayscale. While not as commonly used on the web due to their large file sizes compared to compressed formats like JPEG or PNG, BMP files still support a range of color depth options.
JPEG and BMP image types use different programs and algorithms to record and store the data. The BMP (bitmap) is the older format while the JPEG (Joint Photographic Experts Group) format is more recent. One difference between a JPEG and a BMP file is that the bitmap file is larger in size. This is due to the JPEG file being compressed which in turn causes a loss in picture quality.
For digital cameras it is usually format jpg or jpeg.Nevertheless also formats gif, png and bmp are used.
