HDR to PDB conversion is the process of transforming a High Dynamic Range (HDR) image file into a PDB image container or palette-based bitmap format. This conversion typically involves tone mapping and color quantization to adapt HDR's wide luminance and color range into the more limited color/format constraints of PDB outputs while preserving visual detail where possible.

The MIME type for HDR files is image/vnd.radiance, primarily used for storing high dynamic range images in radiance format. PDB files usually have the MIME type chemical/x-pdb or application/octet-stream depending on the use case, often related to protein data or specialized image data. Codecs for HDR focus on preserving luminance information in a wide color range, while PDB formats rely on specific parsers suitable for 3D structure data or particular image renderers.
The PDB (.PDB) format is commonly used for image. Understanding its characteristics can be helpful when converting to or from other formats like HDR.
While specific technical details aren't available here, PDB files generally serve the purpose of storing image effectively within their domain.
Convert your HDR files to the PDB format effortlessly with our online HDR to PDB converter. Designed for simplicity and speed, this tool allows users to transform HDR images into PDB files without any software installation. Whether you are working in the Image category or need specific file type conversions, our converter ensures high-quality results every time.
HDR files typically store high dynamic range imaging data, capturing detailed light information, whereas PDB files are commonly used for 3D structural data or protein data bank files. HDR focuses on photographic quality and image detail, while PDB serves specialized purposes such as molecular modeling or specific image types. Choosing between HDR and PDB depends on your project’s requirements for image fidelity versus structural data compatibility.
Keep HDR sources under 250 MB for fastest browser-based conversions; split or downscale very large panoramas before converting.
Use tone mapping (filmic or Reinhard) to preserve highlight/shadow detail when mapping HDR to PDB’s limited range—preview results before finalizing.
Enable optimized palette generation and dithering for PDB to reduce banding while keeping file sizes small; avoid aggressive quantization if visual fidelity is critical.
For batch conversions, process HDR files to a consistent color space and resolution first to ensure uniform PDB outputs and faster processing.

Format limitation: PDB targets indexed or device-specific palettes and cannot store true floating-point HDR data, so absolute dynamic range and some color precision will be lost.
