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.
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 SAI2 file after converting to PSB may differ slightly from the original. The most important information should be kept, but if you want the file after conversion from SAI2 to PSB 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 SAI2 to PSB does not meet your expectations, you can simply try to find on the Internet a different version of your file in SAI2 format, properly converted to a PSB file by someone else. If this fails, use the information provided in the further part of the website.
If after converting the file SAI2 the desired result was not achieved, you can try to change the format of SAI2 file to other than PSB. 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 SAI2 file converted by someone else, and the attempt to convert it to PSB 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 SAI2 file in its original format (without conversion to PSB file). Such a solution will be difficult to implement, but it certainly will give the best result.
