Convert your PNG images to BMP in seconds. PNG stores every pixel exactly and keeps transparency, so quality is perfect — but files are larger than JPG or WebP. BMP is uncompressed, so it opens everywhere and never loses quality — but the files are very large.
BMP is uncompressed and opens in virtually any program, at the cost of much larger files.
How to convert PNG to BMP
- Add your PNG file. Drag and drop your PNG file onto the box, or click to browse.
- Output is set to BMP. The format is already set to BMP. Change it if you need a different output.
- Download. Click Convert and your BMP file downloads automatically.
PNG vs BMP
PNG is lossless and supports transparency — best for logos, icons, screenshots, and any graphic with sharp edges or a transparent background. BMP is uncompressed and universally readable — best for legacy software and lossless interchange where compatibility beats file size.
Heads up: BMP cannot store transparency, so transparent areas in your PNG become white. To keep a transparent background, convert to WebP or keep it as PNG instead.
Is it private?
Your PNG files are converted entirely inside your browser. Nothing is uploaded to a server, so your images stay completely private — and conversion is instant, even offline.
