Image Tools

BMP to PNG

Converts one BMP image to PNG in your browser. BMP is typically stored uncompressed, and PNG stores the same pixels losslessly, so the output is normally much smaller with no loss of detail.

  • Output is PNG, which is lossless, so the pixels are preserved

  • No options to set: the file is decoded and re-encoded as PNG
  • Runs in your browser using the canvas API; the file is not uploaded for the conversion

FAQ

Why is the PNG so much smaller than my BMP?

BMP files are commonly stored without compression, so file size grows with pixel count. PNG applies lossless compression to the same pixel data, which usually shrinks the file a lot without changing how the image looks.

Does converting BMP to PNG lose any quality?

No pixel data is discarded by the PNG encoding, so the image should look identical. Anything the BMP had in the way of unusual colour depth is normalised to the browser's standard 8-bit-per-channel canvas.

My BMP will not open. Why?

The tool relies on your browser being able to decode the file. Unusual BMP variants, such as some older compressed or very low colour-depth types, may not load, in which case an error is shown instead of a result.

Can I convert BMP to JPG here?

Not on this page, which outputs PNG only. The Image Converter tool offers PNG, JPEG and WebP output.
