PSB file contains a large Photoshop document project, of size larger then 30 000 by 30 000 pixels, saved in proprietary format developed by Adobe. PSB can store images up to 300 000 by 300 000 pixels. For smaller projects the PSD format is used.
Files in the JP2 format are generated by the JPEG 2000 Core Coding software and are used in order to store compressed bitmap images . JP2 files are also known as JPX because they differ only regarding the name of the extension.
After converting the file to the new format, you will be able to use other programs to support it. Keep in mind, however, that the PSB file after converting to JP2 may differ slightly from the original. The most important information should be kept, but if you want the file after conversion from PSB to JP2 to be the same, you have to do this carefully and choose the proper application from the list below.
There is no guarantee, of course, that the conversion will come up to all your expectations, but it will certainly help you. If, after all, the effect of converting PSB to JP2 does not meet your expectations, you can simply try to find on the Internet a different version of your file in PSB format, properly converted to a JP2 file by someone else. If this fails, use the information provided in the further part of the website.
If after converting the file PSB the desired result was not achieved, you can try to change the format of PSB file to other than JP2. On our website you will find more information on the following conversion options
Unfortunately, if after performing the two previously described steps (trying to find your PSB file converted by someone else, and the attempt to convert it to JP2 on your own) you still have a problem with your file, then there are only a few solutions left. You can once again try to find and install an application that can open the PSB file in its original format (without conversion to JP2 file). Such a solution will be difficult to implement, but it certainly will give the best result.
