BMP2 to BMP Converter
FileFlip converts BMP2 to BMP entirely inside your browser, using ImageMagick compiled to WebAssembly. The file is never uploaded to a server: it is read off your disk, converted on your own machine, and saved back by the browser. That means no file-size limit, no queue and no account.
How do I convert a BMP2 file to BMP?#
- Drop your BMP2 file onto the converter at the top of this page, or click it to pick one from your computer. You can add as many as you like.
- Leave the target set to BMP and the conversion starts on its own. FileFlip downloads 14.1 MB of WebAssembly the first time and nothing after that, then runs ImageMagick on your own machine.
- Save the BMP file. Your browser writes it straight to your downloads folder, because there was never a server holding it.
Does converting BMP2 to BMP lose quality?#
No. Converting BMP2 to BMP writes the data out again without discarding any of it, so nothing that was in the BMP2 file is lost on the way. What changes is the size of the file, not what is inside it.
Is it safe to convert BMP2 files online?#
Yes, because nothing is uploaded. FileFlip converts BMP2 files inside the browser tab you already have open, using WebAssembly builds of the same engines a desktop converter would install. Your file is read from your own disk into the page's memory, and no request carrying it is ever made.
You do not have to take that on trust. Open your browser's network panel, run a conversion, and you will see the engine come down and your file go nowhere. There is no upload, no server-side copy, no retention window, and no account tied to what you converted.
How FileFlip works lists every engine, its version and its download size, and shows how to check for yourself that nothing leaves your machine.
What BMP2 to BMP actually does to the file#
Converting BMP2 to BMP runs on ImageMagick, downloads 14.1 MB of WebAssembly the first time and nothing after that, writes the data out again without discarding any of it.

What is a BMP2 file?#
BMP2 is ImageMagick's name for a Windows bitmap saved with the original 12-byte BITMAPCOREHEADER from 1987's OS/2 1.x, an encoding choice rather than a different file format, so the result is an ordinary uncompressed .bmp using the oldest and most limited header structure.
Choose BMP2 only when a specific legacy OS/2 or early-1990s Windows program requires the old-style bitmap header.
Save as standard BMP or BMP3 for anything opened on a modern system, since BMP2's extra compatibility buys nothing there.
What is a BMP file?#
A BMP file holds a device-independent bitmap: a pixel grid stored with a Microsoft-defined header and, in the overwhelming majority of BMP files in the wild, no compression at all.
Use BMP when a Windows-native application, printer driver, or legacy tool specifically expects it, or when pixel data has to be stored with zero encoding overhead for a processing pipeline.
Convert BMP to PNG or JPEG for anything leaving that pipeline, since both produce a far smaller file and PNG matches BMP's lossless, generation-safe quality.
BMP2 to BMP questions people ask#
What is BMP2?
BMP2 is ImageMagick's name for a Windows bitmap written with the original 12-byte BITMAPCOREHEADER from OS/2 1.x, not a separate image format. The file is still a plain, uncompressed .bmp and opens anywhere BMP does.
What's the difference between BMP2 and BMP3?
BMP2 uses the old 12-byte OS/2 1.x header and tops out at 24-bit color with no compression. BMP3 uses the 40-byte BITMAPINFOHEADER that Windows 3.0 introduced, which adds 16-bit and 32-bit pixel formats plus RLE compression, and is the header nearly every modern BMP file actually uses.
Should I use BMP2 for a new project?
No, BMP2 has no advantage on a modern system. Use plain BMP or BMP3 instead, and reach for BMP2 only if a legacy OS/2 or early-1990s Windows application specifically requires that header.
Why are BMP files so much bigger than JPEG or PNG?
Most BMP files store every pixel's color value directly with no compression, so a BMP is close in size to the raw uncompressed image data. JPEG and PNG both apply compression, lossy in JPEG's case and lossless in PNG's, which is why the same photo saved as either is a fraction of the size of a BMP.
