How to Convert Multiple PSD Images to JP2?
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. reaConverter also includes editing tools: resize, crop, rotate, and more.
2. Load your PSD files
Add your PSD 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 PSD 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.
How PSD and JP2 differ in practice
PSD stores pixels without compression loss and JP2 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. One PSD 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.
