WMF to BMP
Converting a .wmf drawing to .bmp interprets the original drawing commands and outputs a portable image. Free, private, and validated — the file never leaves your browser.

Converting a .wmf drawing to .bmp interprets the original drawing commands and outputs a portable image. Windows Metafile, seen as .wmf, is the original 16-bit vector format of Microsoft Windows — a replayable log of GDI drawing commands dating back to the era of Windows 3.0. Enormous amounts of 1990s clip art, including the classic Office galleries, shipped in this format.
A .bmp file is the Windows bitmap format: raw pixel rows written to disk with a small header and, in the common case, no compression at all. Its brute simplicity makes .bmp trivial to read and write from any programming language, which is why it persists in tooling, embedded systems, and quick debugging dumps. For this route the practical draw is dead-simple structure with no decoding step at all and exactly lossless — what you write is what you read — balanced against no effective compression, so files dwarf PNG equivalents of the same image, which is worth knowing before you commit a large batch.
Why convert WMF to BMP?
The practical trigger for this conversion is usually a mismatch: with .wmf, the 16-bit coordinate space rules out precise or large drawings. Switching to .bmp buys you dead-simple structure with no decoding step at all, which is why it is the better fit for quick lossless dumps from code, since a writer takes minutes to implement. Because the conversion runs locally, trying it costs nothing but a few seconds of compute on your own machine.
WMF vs BMP at a glance
| Aspect | Windows Metafile (.wmf) | Bitmap image (.bmp) |
|---|---|---|
| Format type | Vector — resolution-independent geometry instead of pixels | Lossless — every pixel or sample is preserved exactly |
| How it stores data | 16-bit records encode GDI calls, capping coordinates at signed 16-bit values and limiting drawing precision | pixels are typically stored uncompressed; optional RLE encoding exists only for 4-bit and 8-bit palette images |
| Strongest at | opening legacy clip-art libraries from the 1990s | quick lossless dumps from code, since a writer takes minutes to implement |
| Weak spot | the 16-bit coordinate space rules out precise or large drawings | no effective compression, so files dwarf PNG equivalents of the same image |
Pick BMP as the output
Select .bmp in the output menu next to each file. The menu only offers targets this engine can genuinely produce, so if BMP is selectable, the route is real and validated.
Convert on your device
Press Convert. The drawing records are interpreted locally and rendered to a validated image without any cloud converter.
Verify and download
Each result is signature-checked before the download unlocks, so a failed encode can never masquerade as a valid BMP file. Outputs keep the original filename with the .bmp extension.
WMF to BMP questions, answered
Will converting WMF to BMP lose quality?
The conversion is exact at the resolution you rasterize to — vectors have no pixels until they are drawn. Pick dimensions that match the largest size you will display, because unlike .wmf, a .bmp raster cannot be enlarged cleanly afterwards.
Is it private to convert WMF files here?
Yes — the .wmf file is processed inside your browser tab and never uploaded. The drawing records are interpreted locally and rendered to a validated image without any cloud converter. Close the tab and the file is gone from memory.
Where will the BMP file work?
Windows treats BMP as a native citizen, and macOS, Linux, and all major browsers open it without complaint. The format's problem is never support but waste: emailing or hosting uncompressed bitmaps burns bandwidth for zero benefit, so converting to PNG is almost always an upgrade.
Will the BMP file be bigger or smaller than my WMF?
It depends on the content: pixels are typically stored uncompressed; optional RLE encoding exists only for 4-bit and 8-bit palette images. Convert one representative file first and compare before batch-processing a large set.
