How to Convert Multiple KMZ Files 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.
2. Load your KMZ files
Add KMZ files to reaConverter. One file or a thousand, the process is the same. Everything runs locally on your machine.
You can drag-and-drop files, browse to a folder, or add entire directory trees including subfolders.

3. Select AVIF as output format
Select AVIF from the output format list and set your destination folder. You can also adjust quality and compression settings.

4. Start KMZ to AVIF conversion
Click the Convert button to start. reaConverter will process all your files with the settings you selected.

When finished, your new .avif files will be waiting in the destination folder.
KMZ to AVIF: what to expect from the conversion
KMZ 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.
