PNG to BMP converts PNG images into Windows BMP (bitmap) files. BMP stores raw, uncompressed pixels, which some imaging tools, scanners, and embedded systems expect. Converting a PNG to BMP produces a clean, uncompressed bitmap of the image.
This converter decodes your PNG with the browser's image engine and writes a standard 24-bit uncompressed BMP. Because 24-bit BMP has no alpha channel, transparency is composited onto a white background. Nothing is uploaded to a server.

A compressed PNG converts to a larger, uncompressed 24-bit BMP.
image.png (320 KB, PNG)image.bmp (2.3 MB, 24-bit BMP)How This Tool Works
The browser decodes the PNG to canvas pixels, composites any transparency onto white, and writes a 24-bit uncompressed BMP file for download.
Technical Stack
Format
Output is a 24-bit BI_RGB BMP with bottom-up rows — the most widely compatible bitmap variant.
Privacy
Your image never leaves the browser; conversion is fully client-side.
