Why Convert PNG to BMP?

Some legacy Windows applications, embedded systems, and firmware tools only accept uncompressed BMP input. Converting PNG to BMP produces the raw bitmap those tools expect.

Common use cases

  • You have a PNG file and need it in BMP format for exchanging images with legacy windows applications.
  • The target software or platform requires BMP but your file is in PNG.
  • You want to reduce file size or improve compatibility without using desktop software.
Keep in mind: No compression — BMP files are far larger than PNG at identical quality, making them impractical for web use or sharing.

How to Convert PNG to BMP

  1. Upload or drop your PNG file into the converter above.

About the Formats

PNG (Portable Network Graphics)

PNG uses lossless compression, preserving every pixel of the original without any quality degradation. It supports full alpha-channel transparency, making it ideal for logos, icons, UI elements, and any image that requires a transparent background or pixel-perfect fidelity.

Compatibility: Universal — supported by all browsers, operating systems, and image editors.

BMP (Bitmap Image File)

BMP is an uncompressed raster format from the early days of Windows. Every pixel is stored without compression, which makes BMP files large but completely lossless and trivially simple to read — the reason it survives in embedded systems, scanners, and legacy Windows software.

Compatibility: Supported by all major browsers, Windows, macOS, and virtually every image editor.

100% Private & Browser-Based

For browser-based conversion, files up to 50 MB work best. Very large files may take longer depending on your device. We recommend splitting very large files before converting.
