HDR image (OpenEXR). EXR is lossless, so nothing is lost from the image during conversion. RAW files are large, so each photo may take a few seconds.

Conversion happens inside your browser; your files are never sent to a server.

3. Press "Convert" and download the EXR files one by one or as a ZIP.
