PNG to BMP Converter
/png-to-bmpConvert PNG images into classic BMP (bitmap) files with uncompressed 24-bit pixels for maximum compatibility.
Some systems, printers, and legacy software still demand uncompressed BMP files. This converter produces classic 24-bit bitmap files from PNG images with maximum compatibility. It is the dependable path when nothing else accepts PNG. Conversion happens entirely in your browser.
Industrial printers, kiosk displays, lab instruments, and medical devices frequently accept only uncompressed BMP files, a requirement that modern graphics software no longer offers as a save option. When a production system's firmware expects a 24-bit bitmap with exact pixel layout, converting your PNG is the reliable path. The uncompressed file guarantees the device reads raw scanlines without dealing with PNG's compression or color-profile chunks, eliminating the mysterious image-corruption and blank-output failures that appear when a device silently rejects modern formats.
Retro game engines, embedded framebuffers, and texture tools often demand pixel-exact BMP data so they can address memory directly. PNG's lossless compression is fine for storage, but many engines load bitmaps by mapping the file into memory and reading raw pixel values. Converting to 24-bit BMP gives you a file whose pixel layout matches what the engine expects, with no decoding step and no chance of compression-dependent offsets. For sprite sheets and UI assets that must render identically byte for byte, this is the dependable format bridge.

FAQ
Frequently asked questions
Everything you need to know about png to bmp converter.
Why convert to BMP?
BMP is universally readable with zero compression, which makes it useful for embedded systems, printers, and legacy software that cannot read PNG.
What bit depth is used?
The output is an uncompressed 24-bit BMP, the most widely compatible variant, with a bottom-up row layout and a standard BITMAPINFOHEADER.
Is transparency preserved?
No. 24-bit BMP has no alpha channel, so transparency in the source PNG is dropped and only RGB pixels are written.
Will the file be larger?
Yes. BMP stores every pixel uncompressed, so the file is typically much larger than the PNG source — that is the cost of maximum compatibility.
Which PNGs are supported?
8-bit grayscale, RGB, and RGBA PNGs are supported; 16-bit, palette, and interlaced images produce a clear error instead of a bad file.
