The pbz file extension is associated with Google Picasa, a photo and image editor and manager from Google. Picasa was also available as an online photo-sharing service.
A pbz file is a compressed ZIP archive used by the Picasa Button API. It contains Picasa button files (pbf) and Photoshop files (psd).
The PBF file contains the settings for an individual Picasa button, while the PSD file contains the button graphics.
Google Picasa was available for Microsoft Windows, Apple macOS and Mac OS X, and Linux/Unix. It is obsolete and has been replaced by Google Photos.
To view a pbz file, open it with WinZip, WinRAR, or another utility that supports ZIP archives. Because a PBZ file is a ZIP archive, it can also be renamed with a .zip file extension before opening it.
Extracting the archive displays the included PBF and PSD files. The Picasa software associated with the file is obsolete.
A pbz file does not normally require conversion. It is already a ZIP archive, so changing its file extension to .zip or extracting it provides access to its contents.
