Frequently Asked Questions
BMP (Bitmap) is an uncompressed raster graphics image file format used to store bitmap digital images. It stores images pixel by pixel without compression, resulting in large file sizes but perfect quality.
To convert BMP to PNG, upload your BMP file using our converter above, select PNG as the output format, and click convert. This will significantly reduce file size while maintaining the same visual quality.
BMP files are large because they store image data without any compression. Every pixel is stored with full color information, making them much larger than compressed formats like JPG or PNG.
Use BMP when you need uncompressed image data, for Windows applications that specifically require this format, or when working with images that will be edited multiple times and you want to avoid compression artifacts.
Standard BMP format does not support transparency. If you need transparent backgrounds, convert your BMP file to PNG, WebP, or another format that supports transparency.
BMP files are uncompressed by nature. To reduce size without quality loss, convert to PNG which uses lossless compression. You can also reduce dimensions or convert to modern formats like WebP lossless.
Yes, BMP files can be opened on Mac and Linux, though they're primarily a Windows format. Most image viewers and editors support BMP across all platforms. For better compatibility, consider converting to PNG or JPG.
Both are uncompressed formats, but TIFF is more versatile with support for multiple pages, better metadata, various compression options, and cross-platform compatibility. TIFF is preferred for professional and archival use.
Upload your BMP file, select JPG as output format, and choose appropriate quality settings (80-90% for web). This will dramatically reduce file size making it suitable for web use and email sharing.
Most web browsers don't support BMP files natively. Convert to web-friendly formats like JPG, PNG, or WebP for browser compatibility. These formats are also much smaller and load faster.
