How to Open .BMP Bitmap Image Files

Updated: February 2026

The .BMP file format (Bitmap) is an uncompressed raster image format developed by Microsoft. BMP files store images pixel-by-pixel without compression, resulting in large file sizes but perfect quality preservation.

Opening BMP Files

All operating systems include native BMP support: Photos (Windows), Preview (Mac), or Image Viewer (Linux). Simply double-click to view. Web browsers also display BMP files.

Free BMP Editors

  • Paint: Windows built-in editor for basic BMP editing
  • GIMP: Professional free editor with full BMP support
  • Paint.NET: User-friendly Windows image editor
  • IrfanView: Fast viewer/editor for Windows
  • Photopea: Online editor supporting BMP format

When to Use BMP

BMP is rarely used today due to large file sizes. It's useful for archiving images without any compression loss or when compatibility with legacy Windows software is required. For most uses, PNG is better.

Converting BMP Files

Convert BMP to PNG for lossless compression or JPEG for smaller files. Use any image editor (GIMP, Paint.NET) or online converters. PNG offers same quality with much smaller file size.
