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/use 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 greyscale filter to the image. These additional options are available within the Options tab. Along with Greyscale, you can also mirror/flip the image if needed. For single BMP file uploads you will also see options to resize and rotate your image.
Here are 2 simple steps to convert your BMP to PNG.
First click the "Upload..." button, select your BMP file to upload. Select any configuration options. When the BMP to PNG conversion has completed, you can download your PNG file straight away.
We aim to process all BMP to PNG conversions as quickly as possible, this usually takes around 5 seconds but can be more for larger more complex files so please be patient.
We aim to create the most accurate conversions with our tools. Our tools are under constant development with new features and improvements being added every week.
Yes, of course! We do not store the BMP file you submit to us. The resulting PNG file, once created is deleted 15 minutes after upload and the download link will expire after this time.
Yes! Our BMP to PNG tool will run on any system with a modern web browser. No specialist software is needed to run any of our conversion tools.
Yes. Although you can use an Ad Blocker, if you like our BMP conversion tool please consider white-listing our site. When an Ad Blocker is enabled there are some conversion limits on some of our tools and processing/conversion times will be longer.
Yes! Our BMP tool supports full batch conversions. You can upload up to 25 BMP files at a time. Our tool will convert them all as quickly as possible. Once completed, you can either download the PNG files individually or download them all in a single ZIP file.
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 colour depths ranging from monocrome 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.
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-1990's 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.
