BMP2 to MS Converter
FileFlip converts BMP2 to MS entirely inside your browser, using ImageMagick, MuPDF and Pandoc 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 MS?#
- 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 MS and the conversion starts on its own. FileFlip downloads 79.9 MB of WebAssembly the first time and nothing after that, then runs ImageMagick, MuPDF and Pandoc on your own machine.
- Save the MS file. Your browser writes it straight to your downloads folder, because there was never a server holding it.
Does converting BMP2 to MS lose quality?#
No. The BMP2 picture is placed into the MS document at its full resolution, so every pixel reaches it intact. What you give up is that it becomes a picture inside a document rather than text.
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 MS actually does to the file#
Converting BMP2 to MS runs on ImageMagick, MuPDF and Pandoc, downloads 79.9 MB of WebAssembly the first time and nothing after that, places the picture into the document at full resolution.
| Engine | ImageMagick, MuPDF and Pandoc |
|---|---|
| Conversion path | 3 steps: BMP2 → PNG → HTML → MS |
| Downloaded to your browser | 79.9 MB, once, then cached by your browser |
| Quality | Pixels preserved |
| You get back | One file |
| Where it runs | In a background worker, so the page stays responsive |
Worth knowing before you start:
- the picture is placed in the document as a picture; no text is recognised out of it
- the file passes through HTML on the way, so anything HTML cannot express does not survive
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 an MS file?#
An MS file is a troff document marked up with the ms macro package, one of the original Unix macro sets for typesetting papers, letters and reports through groff or troff.
Use the ms macros to produce a document on a minimal Unix system where a full TeX install isn't available or wanted.
Convert ms output to PDF or HTML when the reader needs a normal document instead of a file that has to run through troff first.
BMP2 to MS 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.
What is an .ms file?
An .ms file is plain text written with the ms macro package for troff, one of the original Unix formatters for papers and reports. It's read by feeding it to groff or troff rather than opening it in a document viewer.
