How to Convert Multiple CR3 Images to AVIF?
1. Download and Install reaConverter
Download reaConverter and install it in seconds. The setup is straightforward — no complex configuration, no extra software required. Built-in editing tools let you resize, crop, or watermark as you convert.
2. Load your CR3 files
Start reaConverter and add your .cr3 files. The software processes everything locally, so your files never leave your computer.
Select CR3s from a folder or drag-and-drop them directly into the reaConverter window.
3. Select AVIF as output format
Choose AVIF as the target format. Pick a destination folder or let reaConverter save files alongside the originals.
4. Start CR3 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.
Before you convert CR3 to AVIF
CR3 files hold unprocessed sensor data, so white balance and exposure are still adjustable. Converting to AVIF bakes those decisions into the pixels, and highlight recovery is no longer available afterwards. Set white balance and exposure before the run rather than after. CR3 carries 14 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.
