PFM to RB conversion is the process of transforming images stored in the Portable Float Map (PFM) format—a high dynamic range, floating-point raster used for storing precise HDR image data—into the RB format, a raster bitmap variant used by certain imaging pipelines and applications. This conversion maps PFM's high-precision float channels into the RB container and encoding, preserving dynamic range where possible or applying tone mapping when required for lower-bit RB targets.

PFM files usually have the MIME type image/x-portable-floatmap and store floating point image data, commonly used in scientific and graphic applications. RB files have the MIME type application/octet-stream and are designed for general data storage with flexible codec support. Conversion involves re-encoding image or data streams to match the target format's specifications.
The RB (.RB) format is commonly used for image. Understanding its characteristics can be helpful when converting to or from other formats like PFM.
While specific technical details aren't available here, RB files generally serve the purpose of storing image effectively within their domain.
Easily convert your PFM files to RB format using our intuitive online converter. Designed for quick and secure file transformations, our tool supports seamless conversion without the need for complex software installations. Whether you're working with PFM files for image or data purposes, converting them to RB format has never been easier.
PFM files are typically used for storing high-quality image data with less compression, while RB files are optimized for broader compatibility and efficient storage. RB format often supports more advanced features and codecs compared to PFM. Choosing RB can enhance workflow adaptability across various platforms.
Keep PFM source sizes reasonable: aim for images under 5000×5000 pixels for faster browser-based conversion and lower memory use.
Preserve quality by choosing 16-bit RB output or lossless compression when the workflow requires high dynamic range detail.
For display or web delivery, apply tone-mapping and set RB to 8-bit with gamma correction to avoid washed-out or clipped highlights.
Use batch conversion for many files but throttle concurrency: convert in groups of 10–20 to prevent CPU/memory spikes.

Format limitation: RB may not support full floating-point HDR without tone-mapping; expect quantization when targeting 8/16-bit RB outputs.
