How can I convert JP2 to JPEG?

One of the most common questions about JPEG is, “What’s the difference between JPEG 2000 (JP2) and JPEG?” So, before we tackle the conversion question let’s get a general brief on the two file formats.

In 2000, Joint Photographic Experts Group developed JP2. It was developed to provide better image quality and compression than JPEG. JP2 uses either a lossy or lossless compression algorithm. Unlike JPEG, JP2 uses a wavelet compression codec while the former uses the Digital Cosine Transform codec.

JP2 is a more modern format with totally different compression algorithms producing richer and quality images. It can also handle 256 information channels while JPEG can only handle RGB data. When it comes to the compression ratio, JP2 can do 20-200% higher than JPEG. Besides, you can clearly display images at different sizes and resolutions.

In short with JP2, you get an error-resilient format that has flexible progressive decoding.

If you want to open a JP2 file, use IvanView, ACD Systems Canvas X 2019, Adobe Photoshop CC 2019, CorelDraw Graphics Suite 2019, XnView MP, Apple Safari, and Apple Preview.

However, it’s not as popular as JPEG. As a result, it has a limited browser, application, and device support. Additionally, it offers no transparency preservation. For this reason, converting JPEG 2000 to JPEG is the most popular solution.
