How to Convert Multiple PPM 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. Apply image edits like resize, crop, or color adjustment while converting.
2. Load your PPM files
Load your PPM files into reaConverter. You can add individual files or point to folders, and the software will queue everything automatically.
Select PPMs 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 PPM 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.
PPM to AVIF: what to expect from the conversion
PPM 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. PPM 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.
