How to Convert WebP to HDR

Radiance HDR (.hdr) was created in 1991 and was the original standard for storing high dynamic range image data, remaining in use today by architectural lighting tools and some 3D rendering software. Converting a standard WebP to HDR doesn't add dynamic range the original 8-bit WebP never captured — the conversion changes the container format and storage approach rather than adding highlight or shadow detail that wasn't there to begin with.

This is useful specifically when a piece of lighting, rendering, or visualization software expects a .hdr file as input rather than WebP, regardless of whether the source data is true HDR or not.

1. Install Batchify Image Converter and Resizer Pro on your Windows PC.
2. Open the app and select Batch Mode for multiple files, or Individual Mode for a single WebP file.
3. Drag your WebP file or folder into the app window, enabling recursive folder scanning if needed.
4. Set the "From" format to WebP and the "To" format to HDR.
5. Click Convert. HDR files are written to the output folder, fully offline.
