KEEP
Both files live on your device.
No upload, no cloud.
What it actually does
01
DECODE
PNG decoded by the browser. Pixel grid extracted.
Lossless source. Every pixel exact.
02
ENCODE
BMP written as standard 24-bit uncompressed RGB.
Predictable byte layout. Windows-shaped. Legacy-tool-friendly.
04
BATCH
Drop a folder.
Each PNG becomes a BMP in parallel.
How it works
- Open morph.cool in any modern browser.
- Drop your .png file onto the drop zone, or click to browse.
- Pick BMP as the output format.
- Download your converted .bmp file. Done in seconds.

Why it lives in the tab
PNG is what BMP would have been if it were designed for the modern web. Going the other direction — PNG to BMP — only makes sense when something downstream specifically wants raw uncompressed pixels in the Windows-bitmap byte order. We do that conversion locally so the file never has to round-trip through someone else's server.
Frequently asked
Why convert PNG to BMP?
Some industrial software, embedded systems, and legacy Windows applications only accept BMP. PNG → BMP is the predictable raw-pixel handoff.
Will the file be much larger?
Yes — BMP is uncompressed, PNG uses DEFLATE. Expect 2–4× size increase.
Does the alpha channel survive?
Standard 24-bit BMP doesn't carry alpha. The transparent areas become solid background. For alpha-preserving output, use PNG → PNG (which is a no-op).
Does this batch?
Yes. Drop a folder; each PNG becomes a BMP.
Is the conversion lossless?
For 24-bit RGB content, yes. For PNGs with alpha, the alpha is dropped (BMP limitation).
