Reduce size of PSB Files
PSB format can be easily compressed if you save it as PSD, but PSD format doesn't support the image that are more than 30000 pixels on width or height. In this case compressing PSB file is more complex solution. You can try PSB Compress Software but we can not guarantee that final compressed PSB file will be readable. This app uses not documented features of PSB format. To improve chance of the correct work, please try compress features that will not remove important data. Reduce size of PSB provided "as is". It's better to use common PSD Size Reduce Application
Drag and drop a file or select add Image
You can reproduce the main functionality of this built-in app using Aspose.PSD for .NET

PSB files can be up to 2gb, so you can get the case when this app is can not upload PSB file to reduce its size. In this cases it's better to use on-premise psd format solution as Aspose.PSD and write compress code by yourself. The code examples hot to compress PSB format can be found in this article, just switch the tabs in built-in PSB File Reduce App
