How to Convert Multiple AVIF Images to JP2?
1. Download and Install reaConverter
reaConverter installs quickly on any Windows PC. No dependencies, no bloatware — just a clean setup that's ready to use immediately. Built-in editing tools let you resize, crop, or watermark as you convert.
2. Load your AVIF files
Add your AVIF 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 JP2 as output format
Pick JP2 as the output format. Set the destination folder and optionally configure resolution, quality, or file naming.
4. Start AVIF to JP2 conversion
Start the conversion with one click. reaConverter handles everything and notifies you when it's done.
When the batch finishes, your JP2 files are ready in the destination folder you chose earlier.
AVIF to JP2: what to expect from the conversion
AVIF and JP2 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. One AVIF file can hold several pages or frames, while JP2 holds one image each. reaConverter writes a separate output file per page and numbers them, so a single input can produce a whole folder of results.
