FAQ
HDR to AVIF Conversion
What are HDR files?
The HDR file format (.hdr) is a raster image format designed to store high dynamic range (HDR) data, capturing a wider range of brightness levels than standard formats like JPEG or PNG. Developed by Radiance, it uses a 32-bit floating-point representation per channel, enabling realistic lighting, shadows, and highlights.
What are AVIF files?
AVIF is a new image format launched at the end of 2020. AV1 Image File Format was developed by the Alliance for Open Media in collaboration with Netflix, Google and Cisco. This format was created to be an open-sourced and royalty-free image format with a super-compression efficiency. Multiple graphics compression tests show that the .avif format outperforms the JPEG, PNG and WebP image formats for its image quality to compressed file size ratio.
