What is PGM format used for?

PGM (Portable Gray Map) is commonly used in scientific computing, computer vision, and academic settings. Its simple structure makes it easy to read and write programmatically, and it's supported by most image processing libraries like OpenCV, MATLAB, and ImageMagick.

Will my color image become black and white?

Yes, PGM is a grayscale-only format. The converter transforms your color BMP image to grayscale using luminance-preserving weights that maintain perceived brightness from the original colors.

What is the difference between P2 and P5 PGM formats?

P2 is ASCII format where pixel values are stored as human-readable numbers, while P5 is binary format with raw byte values. Our converter uses P5 for smaller file sizes and faster processing while maintaining full compatibility.

Can I open PGM files in regular image viewers?

Most modern image editors like GIMP, Photoshop, and IrfanView support PGM format. Scientific tools like MATLAB and Python's PIL/Pillow can also read PGM files directly.

Is the BMP to PGM conversion completely free?

Yes, our BMP to PGM converter is completely free with no hidden costs, watermarks, or limitations. Convert as many images as you need without any registration or subscription requirements.

Are my images secure when using this converter?

Absolutely. All image processing happens locally in your browser. Your BMP files never leave your device or get uploaded to any server, ensuring complete privacy and security for your images.
