PEF vs BMP Format Comparison

Aspect	PEF (Source Format)	BMP (Target Format)
Format Overview	PEF Pentax Electronic Format RAW image format capturing unprocessed sensor data from Pentax digital cameras, preserving maximum detail. RAW	BMP Bitmap Image File Raster graphics image format for storing bitmap digital images, supporting uncompressed and lossless formats. Lossless
Compression	Lossless or minimal compression retaining all sensor data for maximum post-processing flexibility.	Typically uncompressed or RLE compression, preserving pixel-perfect fidelity.
Color Depth	Typically 12-bit per channel RAW data with extensive dynamic range.	Supports 1-bit to 24-bit or 32-bit per pixel (with alpha channel).
File Size	Large files (20-70 MB) containing full sensor data and metadata.	Large files (5-50 MB) depending on resolution and bit depth.
Processing Stage	Unprocessed RAW sensor data requiring development software for viewing and editing.	Processed, ready for editing, printing, and archiving without further conversion.
Advantages	Maximum image quality and dynamic range Non-destructive editing capabilities Extensive post-processing flexibility Professional photography standard	Uncompressed storage ensures no data loss Wide compatibility with Windows and editors Simple structure for easy processing Supports alpha channel in BMP v4 and later
Disadvantages	Requires specialized software for viewing and editing Limited compatibility with standard viewers	Large uncompressed files impact storage and bandwidth No native web support without conversion Limited compression options compared to modern formats
Use Cases	Professional photography workflows Fine art and commercial photography High-end photo editing and retouching	Image archiving and printing Windows application development resources Lossless editing workflows
Tooling & Ecosystem	Pentax Digital Photo Professional and Lightroom Professional RAW processing tools Custom camera profiles and plugins	All Windows systems and basic editors Graphics and image processing libraries Design and printing software
Web Compatibility	No direct browser support; requires conversion for web display.	Not natively supported on web; requires conversion to web formats.
Metadata Support	Extensive EXIF data and proprietary metadata preserved.	Limited metadata in BITMAPINFOHEADER; typically stripped.
Transparency Support	No transparency support; solid RAW data.	Supports alpha channel in newer BMP versions.

Why Convert PEF to BMP?

Converting PEF to BMP provides a simple, uncompressed image format ideal for lossless editing and archival. BMP’s straightforward structure ensures pixel-perfect fidelity and compatibility with a wide range of software.

Our converter retains all color information and allows batch processing to convert multiple PEF files into BMPs, streamlining workflows for printing and processing pipelines.

Use BMP files for high-quality image editing, Windows application development, and archival where no compression artifacts are acceptable.

Key Benefits:

Uncompressed storage for maximum fidelity
Wide software compatibility, especially on Windows
Batch conversion for efficient processing
Fully online—no software installation needed

Ideal for developers, archivists, and photographers, our PEF to BMP converter delivers uncompromised quality and ease of use.
