Understanding the File Extension – PSD & PSB
The file extension “.psd” stands for Photoshop Document and “.psb” is an acronym for Photoshop Big. A PSD file is used to save image edits made in Adobe Photoshop, while a PSB file can be used to store larger images of over 30,000 pixels and up to 300GB in size. Both formats are exclusive to Adobe Photoshop and are compatible with other software programs from the Creative Suite, such as Illustrator or InDesign.
What is a PSD File and How Can You Create It In Photoshop?
A PSD file is the default file format for Adobe Photoshop, and it allows users to save their image without losing any of the layers or other editing features. It also stores all of the layers in a flat format, which means that they won't be visible when opened in another program. The maximum image size for a PSD file is 30,000 pixels by 30,000 pixels and is typically used for web or print images.
To create a PSD file in Adobe Photoshop, open the program and click “File” > “New”. Select the size of your canvas as well as any other settings you'd like to include such as color mode (RGB or CMYK) and resolution (in pixels per inch). Once you have finished making your edits, save the file as a PSD by clicking “File” > “Save As…” and selecting “PSD” in the drop-down menu.
What is a PSB File and How Does It Vary From A PSD?
A PSB file is slightly different from a PSD in that it can store larger images with sizes of up to 300GB and more than 30,000 pixels. This means that you can create very large projects such as posters, billboards or murals without any compression of the original image data. While the quality of the image may suffer slightly due to its size, the advantage of a PSB file is that you can make very detailed edits without loss of data.
