How to Convert Multiple SCN Images to AVIF?
1. Download and Install reaConverter
reaConverter is a standalone Windows app — download, install, and start converting SCN files in under two minutes. You can also resize, crop, and adjust images during conversion.
2. Load your SCN files
Add your SCN files to reaConverter. Whether it's a handful or an entire archive, the batch engine processes them efficiently.
Browse for files, drag them in, or add entire folders at once. reaConverter queues everything automatically.
3. Select AVIF as output format
Pick AVIF as the output format. Set the destination folder and optionally configure resolution, quality, or file naming.
4. Start SCN to AVIF conversion
Start the conversion with one click. reaConverter handles everything and notifies you when it's done.
When the batch finishes, your AVIF files are ready in the destination folder you chose earlier.
Before you convert SCN to AVIF
SCN carries 16 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. SCN and AVIF both compress by discarding data, so this is a re-encode rather than a copy. The output is built from already-compressed pixels, and the artefacts of the first encode are carried into the second. Use a high quality setting, and convert from the original whenever you still have it.
