JPEG to HDR conversion is the process of transforming a standard dynamic range JPEG image into a high dynamic range (HDR) image format that preserves and expands tonal range and detail in highlights and shadows. This typically involves tone-mapping, merging exposure information (when available), and converting color and metadata to an HDR-capable container to enable richer contrast and luminance on HDR displays.

JPEG files use the MIME type image/jpeg and rely on lossy compression codecs such as DCT-based algorithms to reduce file size. HDR images commonly use the MIME type image/vnd.radiance or image/hdr and support formats that store extended luminance and color information. Typical HDR use-cases include high-end photography, 3D rendering, and display on HDR-capable monitors and TVs.
The HDR (.HDR) format is commonly used for image. Understanding its characteristics can be helpful when converting to or from other formats like JPEG.
While specific technical details aren't available here, HDR files generally serve the purpose of storing image effectively within their domain.

JPEG is a widely-used compressed image format optimized for smaller file sizes but with limited dynamic range. In contrast, HDR images store a wider range of luminance and color information, enabling more vivid and true-to-life visuals. While JPEGs are suitable for everyday viewing, HDR is preferred for professional photography and advanced display technologies.
Keep source JPEGs under 20–50MB for faster processing; very large single files increase conversion time and memory use.
For best results, start from the highest-quality JPEG (lowest compression) and, if possible, use originals with embedded color profiles to preserve color fidelity.
If you have bracketed exposures, combine them into an intermediate HDR merge first; converting a single LDR JPEG to HDR can expand tonal range but cannot recreate lost exposure data.
Use batch conversion for large sets but monitor memory and CPU: convert in smaller groups if you encounter slowdowns or crashes.
