What Is BMP to PNG Conversion?

BMP (Bitmap) is an uncompressed raster image format native to Windows, producing large file sizes. PNG (Portable Network Graphics) is a lossless compressed format that offers the same image quality at a significantly smaller file size with full transparency support and universal browser compatibility. Converting BMP to PNG is ideal for reducing storage and sharing images on the web.

Frequently Asked Questions

Will the PNG be the same quality as the BMP?

Yes. PNG uses lossless compression, so every pixel is preserved exactly. There is no quality degradation.

Why is the PNG smaller than the BMP?

BMP files are uncompressed, storing raw pixel data. PNG applies lossless compression (DEFLATE), which typically reduces file size by 50–80% with no quality loss.

Does PNG support transparency from BMP?

BMP files rarely contain transparency, but if your BMP has a 32-bit depth with an alpha channel, the PNG output will preserve the alpha information.

Is my BMP file uploaded to a server?

No. Everything runs in your browser using the HTML5 Canvas API. Nothing is uploaded or stored.
