What Is a PNG to BMP Converter?

A PNG to BMP converter expands compressed PNG images into raw, uncompressed BMP files. When a tool, printer, or embedded system demands plain bitmap data with no compression whatsoever, BMP is the format it wants.

The conversion happens entirely in your browser — instant, private, and free.

Why Convert PNG to BMP?

BMP's simplicity is its virtue: a fixed header followed by raw pixels. There is no codec, no color profile interpretation, and no decoder variance — every program that reads BMP sees identical data. Certain Windows software, industrial equipment, and hardware pipelines require exactly that.

If your target system accepts BMP, this converter produces it faithfully from any PNG.

Raw uncompressed pixel data
No codec or decoder variance
Required by certain legacy systems
Predictable, fixed structure

Frequently Asked Questions

Substantially — expect 3–10× the PNG size. A 3 MB PNG photo can become a 30+ MB BMP.
Not reliably. BMP alpha support is inconsistent across readers, so treat the output as opaque.
Both formats are lossless, so converting PNG to BMP preserves every pixel exactly — it only changes how they're stored.
Legacy Windows applications, some industrial printers, embedded displays, and scientific instruments still require uncompressed BMP input.
Never. All processing happens on your device. Your files never touch our servers.
