Converting JPEG 2000 files using Contenta Converter PREMIUM

JPEG 2000, or JP2, is a variation of the more popular JPEG format. The JPEG 2000 has the same benefits and issues as JPEG with the primary difference being that if a file is highly compressed – a JP2 file will retain more quality than a JPG file.

The main limitation with JPEG 2000 is that it is a lossy format. Every time a JPEG 2000 file is edited and saved some visual quality is lost in the process and cannot be restored. Thus JPEG 2000 is not well suited to files that will undergo multiple edits. Indeed, the JPEG 2000 format can not be used in astronomical or medical imaging where the exact reproduction of the data is required.

If you need to edit a JPEG 2000 file, you should save it to a lossless format such as PNG, make the edits, and then create a JPEG 2000 for distribution. This is where Contenta Converter PREMIUM can be a huge assist. Using Contenta Converter PREMIUM you can load a JP2 file and convert it to formats like PNG. I will demonstrate the quick and easy way to do this with Contenta Converter PREMIUM.

Step 1: Select your photos.

Click on the Add Photos button and select from your computer the .JP2 photos you wish to convert. Then click the ‘Next’ button.

Contenta Converter PREMIUM can create JPEG or JPEG2000 images of the exact quality you need using the JPEG quality slider.

The popular JPEG format dates back to 1986 when it was designed by the Joint Photographic Experts Group. The format is popular for two main reasons. First, the files can be compressed which makes it ideal for web usage,where the bandwidth used by an image is important. Second, almost all digital cameras can create images in the JPEG format.

You can also select a different output folder if you want to. This is the location where the files converted to JPEG 2000 will be stored.

The program will default to preserve EXIF/IPTC/XMP metadatas which will preserve all the details about the photo – date it was taken, brand of camera used, model of camera used and much more detail. You can choose to turn this off to make the file a bit smaller or to hide any of that information. You can also choose to reduce the image size and in this example we’ll turn these files into thumbnail size images.
