How to Convert JPEG2000 to AVIF

JPEG2000 and AVIF both improve on older compression methods using more advanced mathematical approaches — JPEG2000 with wavelet-based compression, AVIF with the AV1 video codec — but they serve very different audiences. JPEG2000 is used in medical, satellite, and archival imaging, while AVIF is built for general web and consumer image delivery with far broader browser support.

Converting a JPEG2000 file to AVIF is relevant when archived or specialized imaging content needs to be published or shared more broadly, such as making a satellite image or scanned document viewable on a website, where AVIF's modern compression and wide compatibility are more useful than JPEG2000's specialized features.

1. Install Batchify Image Converter and Resizer Pro on your Windows PC.
2. Open the app and select Batch Mode for multiple files, or Individual Mode for a single JPEG2000 file.
3. Drag your JP2 file or folder into the app window, enabling recursive folder scanning if needed.
4. Set the "From" format to JPEG2000 and the "To" format to AVIF.
5. Adjust the quality setting to balance file size against visual detail.
6. Click Convert. AVIF files are written to your output folder, fully offline.
