PNG to BMP
Converting a .png image to .bmp re-encodes the pixels for a different balance of size, quality, and support. Free, private, and validated — the file never leaves your browser.

Converting a .png image to .bmp re-encodes the pixels for a different balance of size, quality, and support. A .png file is a losslessly compressed raster image with full 8-bit alpha transparency, making it the standard choice for graphics that must stay pixel-perfect. Screenshots, logos, UI assets, and diagrams are the classic .png territory, since sharp edges and flat color survive without compression artifacts.
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 PNG to BMP?
The practical trigger for this conversion is usually a mismatch: with .png, photographic content produces files several times larger than JPEG or WebP. 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.
PNG vs BMP at a glance
| Aspect | PNG image (.png) | Bitmap image (.bmp) |
|---|---|---|
| Format type | Lossless — every pixel or sample is preserved exactly | Lossless — every pixel or sample is preserved exactly |
| How it stores data | uses DEFLATE compression preceded by per-scanline prediction filters (None, Sub, Up, Average, Paeth) | pixels are typically stored uncompressed; optional RLE encoding exists only for 4-bit and 8-bit palette images |
| Strongest at | screenshots and screen recordings exported as stills | quick lossless dumps from code, since a writer takes minutes to implement |
| Weak spot | photographic content produces files several times larger than JPEG or WebP | 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. Decoding and re-encoding happen on your device using the browser's native image pipeline and hand-tuned encoders.
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.
PNG to BMP questions, answered
Will converting PNG to BMP lose quality?
Since png is lossless-oriented and bmp is lossless-oriented, the conversion preserves the source content exactly as stored; no additional compression pass is applied beyond what .bmp itself requires.
Is it private to convert PNG files here?
Yes — the .png file is processed inside your browser tab and never uploaded. Decoding and re-encoding happen on your device using the browser's native image pipeline and hand-tuned encoders. 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 PNG?
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.
What happens to the metadata in my PNG file?
In .png, text metadata lives in tEXt/iTXt chunks and XMP can be embedded there; standardized EXIF arrived late via the 2017 eXIf chunk, so many tools still drop EXIF when writing PNG. Re-encoding through the browser pipeline does not carry embedded metadata into the output, which doubles as a privacy scrub — check the exported file if you specifically need tags preserved.
Can I convert BMP back to PNG?
Yes — the reverse route exists as a separate tool. Bear in mind that round-tripping .png → .bmp → .png is not a perfect undo when any lossy step is involved; keep your original if fidelity matters.
