Free Online PNG to BMP Converter

Convert PNG images to BMP (Bitmap) format with this free online tool. BMP is a widely compatible uncompressed format that works with virtually every application, making it the right choice when you need raw pixel data or legacy software support.

PNG vs. BMP: Key Differences

PNG (Portable Network Graphics) is a lossless format with efficient compression and transparency support, widely used for web graphics and screenshots. BMP (Bitmap) is an older, uncompressed format that stores raw pixel data without any compression, resulting in larger files but guaranteed compatibility with every image viewer and editor. Converting PNG to BMP is useful for legacy systems, embedded applications, or when you specifically need uncompressed image data.

How to Convert PNG to BMP

  1. Upload your PNG file – Select the file from your device, drag and drop, or paste a URL.
  2. Click "Convert to BMP!" – The conversion is instant.
  3. Download the BMP file – Save the converted image to your device.

Important Notes

  • Transparency – Standard BMP does not support transparency. Transparent areas in PNG will be filled with a white background.
  • File size – BMP files are uncompressed and will be significantly larger than the original PNG.
  • Quality – No quality is lost during conversion since both formats store data losslessly.
