BMP to PNG Converter – Professional Bitmap to PNG Conversion

BMP (Bitmap) is an uncompressed image format that stores pixel data without any compression, resulting in large file sizes but perfect image quality. PNG (Portable Network Graphics) is a modern, compressed format that supports transparency and is ideal for web use. Our BMP to PNG converter helps you transition from the legacy BMP format to the versatile PNG format while maintaining image quality.

Why Convert BMP to PNG?

While BMP files offer uncompromised quality, there are many practical reasons to convert them to PNG:

  • Smaller File Sizes: PNG files are typically 50-90% smaller than equivalent BMP files
  • Transparency Support: PNG supports alpha channels for transparent backgrounds
  • Better Web Performance: Smaller file sizes mean faster loading websites
  • Universal Compatibility: PNG works across all modern browsers and devices
  • Lossless Compression: PNG compression doesn't reduce image quality
  • Metadata Support: PNG can store text metadata like copyright information

  • Compression: BMP has no compression, PNG uses DEFLATE compression
  • Transparency: BMP has limited transparency support, PNG supports full alpha channels
  • Web Usage: PNG is web-friendly, BMP is not recommended for web use
  • Color Depth: Both support 24-bit color, PNG also supports palette-based images

  • For Web Graphics: Use PNG for logos, icons, and images with transparency
  • For Photos: Consider JPG for photographic content to reduce file size further
  • For Archival: Keep original BMP files as your master copies
  • For Printing: PNG is suitable for printing if file size isn't a concern
  • For Email: PNG works well for email attachments due to good compression

Frequently Asked Questions

No – PNG uses lossless compression, so the image quality remains identical to the original BMP file. All pixel data is preserved exactly.

Yes – if your BMP file has transparency information, our converter will preserve it in the PNG output using alpha channels.

You can upload files up to 50MB. If your BMP file is larger, we recommend using desktop software for conversion.
