How to Convert Multiple OBJ Files to AVIF?
1. Download and Install reaConverter
First, grab reaConverter from the download button below. Installation is fast, and the software runs offline — no account or signup needed.
2. Load your OBJ files
Launch reaConverter and load the OBJ files you want to convert. Add a few files or thousands, batch processing handles them all.
Drag-and-drop OBJs directly into reaConverter or use the folder browser to load entire directories.
3. Select AVIF as output format
Set AVIF as output format and select where to save your converted files. Customize quality settings if needed.
4. Start OBJ to AVIF conversion
Press Convert to begin processing. You can watch the progress or minimize and let it run in the background.
Your converted AVIF files will appear in the destination folder as soon as processing completes.
Before you convert OBJ to AVIF
OBJ describes geometry rather than pixels, so it has no inherent resolution. The conversion renders it at whatever size you choose, and that choice is final: enlarging the AVIF afterwards will not recover the sharpness. Set the output dimensions or DPI before converting, not after.
