Batch HDR Converter

The Batch HDR Converter allows you to convert multiple images into HDR-supported formats or generate tonemapped HDR-style visuals in bulk. HDR (High Dynamic Range) provides richer colors, deeper contrast, and more detail — perfect for professional imaging, photography, and modern displays.

What Is HDR Imaging?

HDR (High Dynamic Range) is a technique used to capture and display a wider range of brightness and colors compared to standard images. HDR images preserve more shadow and highlight detail, making photos look more realistic and vibrant — especially on HDR-capable screens.

Why Convert Images to HDR in Bulk?

Professional Photography: Convert multiple shots into HDR-ready visuals.
Modern Displays: HDR images look stunning on 4K, OLED, and high-brightness screens.
Better Color & Contrast: Tonemapped HDR enhances depth and detail.
Design & CGI: HDR is widely used in 3D rendering, VFX, and digital art.
Batch Efficiency: Process hundreds of images at the same time.
