In addition, PSB can have up to 300,000 pixels, while PSD file is limited to 30,000. PSB supports all of the same Photoshop features as PSD, making it an attractive option for handling large Photoshop files.
Adobe Photoshop is the primary program to use for opening PSB. It is also the best program for converting PSB to another file format, such as GIF, JPG, EPS, PNG, and several other formats. You can also convert a PSB file without using Photoshop with FreeConvert.com converters like PSB to JPG or PSB to PDF.

WebP is an open-source file type that uses predictive compression to create images that are ideal for web pages and mobile applications. WebP images are as much as 30 percent smaller than JPEG (JPG) and Portable Network Graphics (PNG) files, with similar visual quality. WebP images load quickly on web pages and mobile applications.
The default program for opening WebP is Google Chrome (Chrome), which works across platforms. WebP files also open automatically on GIMP and Microsoft Paint. Besides Chrome, all other web browsers support the WebP format.
Alternative free viewers to try are Pixelmator and Photopea. Also, try Corel PaintShop Pro. Prior to using IrfanView, Windows Photo Viewer, and Adobe Photoshop, be sure to install the plugins for opening WebP.
