How do I convert an AVIF file to ERF with LetsConvert?

Why would I want to convert AVIF to ERF?

ERF is Epson's raw image format, which stores unprocessed sensor data. AVIF files are compressed, so converting to ERF allows photographers to work with the AVIF image in raw-compatible software for advanced editing like white balance and exposure adjustments. It's also useful for archiving in a recognized raw format.

What happens to metadata and quality when AVIF is converted to ERF?

Our converter retains EXIF metadata such as camera make/model and settings. Color profiles (ICC) are embedded to preserve color accuracy. However, since ERF is a raw format, transparency in AVIF is flattened, and any lossy compression artifacts from AVIF remain in the converted file. We use lossless RGB-to-ERF conversion to prevent further quality degradation.
