How to Convert Multiple EXR Images to AVIF?
1. Download and Install reaConverter
reaConverter installs quickly on any Windows PC. No dependencies, no bloatware — just a clean setup that's ready to use immediately. Apply image edits like resize, crop, or color adjustment while converting.
2. Load your EXR files
Load your EXR files into reaConverter. You can add individual files or point to folders, and the software will queue everything automatically.
Select EXRs from a folder or drag-and-drop them directly into the reaConverter window.

3. Select AVIF as output format
Choose AVIF for output and set your save location. reaConverter lets you customize quality and apply edits before conversion.

4. Start EXR to AVIF conversion
Press the Convert button and reaConverter takes care of the rest. Processing time depends on file size and volume.

After processing, find all your new .avif files in the output location. The log shows details for each conversion.
What changes when you convert EXR to AVIF
EXR carries 32 bits per channel and AVIF carries 12, so tonal steps get coarser during conversion. It shows up first in smooth gradients such as skies. If the result will be edited further, move to a 12-bit format only at the very end. EXR stores pixels without compression loss and AVIF does not, so this is a one-way step. Choose a high quality setting, and avoid converting the same file back and forth, because each pass compounds the artefacts.
