Have you encountered a problem with a PSB file? Don’t you know which program opens a file with this extension? You will find all the information you need about working with a PSB file here. In the further part of this page we have added a list of programs that should open your PSB file. It is enough you choose a proper application for your operating system, download and install it.

Description

The PSB format is next to the more commonly used psd format, the second native graphics format of the image editing software Adobe Photoshop. The PhotoShop big file is a lossless graphics format that stores much more information besides pure image data.

Among other things, information about layers, masks, paths as well as alpha channel information and vector elements are stored. Adobe Photoshop is the standard program for professional image editing.

The difference to a normal psd file is the increased maximum resolution and the removal of file limits (Windows 4GB, Mac 2GB). Images in psd format can have a maximum of 30,000 x 30,000 pixels, whereas PSB can have up to 300,000 x 300,000 pixels. Such large pictures are made for example by some professional cameras or are produced in panoramic or satellite images.

The PSB format was introduced with the CS series and therefore can not be processed by older Photoshop versions. Opening a PSB file can cause problems, since the PSB format is not 100% downwards compatible. Each new version of Photoshop has new features that result in new data that will be stored in the PSB file.

In order to be able to save the PSB format, it usually has to be activated via the file handling in the settings. Psb files can only be used by Photoshop CS. Photoshop is available for Windows and Mac OSX.

How to open a PSB file? Advice and guidance

Absolutely most often appearing reason that prevents you from opening the PSB file is the lack of a proper application to support it in your operating system. It is notably the first thing you need to address. When one of the programs to support a PSB file from the list is already installed, you can try to rerun the file. The system should display a message asking you to choose a primary application to support PSB files. At this point we are looking for disk space where the application was installed in and we can link it with a PSB file. Since then, our operating system will use the selected program to support all PSB files.

Other issues

Despite the described problem with PSB there may be many more problems. If the existing operations were not effective, get involved with the following matters:

- verify that the PSB file is not damaged and that it has been downloaded or copied in whole
- verify that the file has a file extension that has not been intentionally changed (for example, if it do not contain other information than its extension suggests)
- make sure again whether the PSB file type is linked in the operating system with a proper program
- make sure that the file is not infected with a virus and you have up to date software and drivers.
