Convert your BMP file to PNG

Convert image files with our easy-to-use and free tool. Our tool lets you upload a BMP (Bitmap Image File) file and, from this, create a new image saved in the PNG (Portable Network Graphics) format that you can then download and edit within image file editors or use for high-definition printing applications. Our conversion tool can also batch convert multiple BMP image files; up to 25 files at a time can be converted.

Along with converting BMP image files to PNG, our tool allows you to also adjust the image with some simple effects, such as applying a grayscale filter to the image. These additional options are available within the Options tab. Along with grayscale, you can also mirror or flip the image if needed. For single BMP file uploads, you will also see options to resize and rotate your image.

Description

The BMP file format is a two-dimensional image file format popular on Microsoft Windows operating systems. Data is stored in the BMP file in a raster format, with pixels being represented using various color depths ranging from monochrome 1-bit per pixel (bpp) to full color 24-bits per pixel.

The format can also contain an image alpha channel, which is typically 8 bits per pixel in size and is used to describe image transparency. BMP files can also optionally be compressed using a lossless compression algorithm, meaning smaller files with no loss of image quality.

Description

The PNG graphics file format is a commonly used format for storing 2D images, which can be highly compressed by the use of a palette if the image has a sufficiently low number of colors (256 colors in general). The PNG file is then further compressed using the DEFLATE compression algorithm to ensure small file sizes that are fast to download.

PNG files are seen as the logical successor to the GIF image file format and was devised in the mid-1990s as a superior format to GIF. PNG files are generally used for company logos, icons, and other non-photographic image content. Saving a digital photo in the PNG format will create a much larger file than an equivalent JPG image, hence the PNG format being unsuitable for most digital photo content.
