What is a BMP file?
BMP (Bitmap) is a raster image format developed by Microsoft. It stores image data pixel by pixel, which makes it simple and widely supported but often results in large file sizes due to a lack of compression.
BMP is mostly used in Windows environments and ideal for storing high-quality images where file size is not a concern. It supports various color depths and is easy to process programmatically.
How to open BMP files
BMP files are supported natively on all major operating systems — including Windows, macOS, and Linux. You can open them with default tools like Paint, Preview, or with editing software like GIMP, Photoshop, or IrfanView.
They can also be converted easily using online platforms such as AnyConv.
