Adobe Photoshop File Format Solution
High Code APIs and free apps for PSD, PSB with ability to reduce size of files and compress using undocumented possibilities
Reduce size of PSD Files
Reduce size of large PSD is a simple operation if you use Aspose.PSD. Reducing of the size can be archieved by removing cache data from PSD Files, Merging Layers, Converting to PSD Format with the less bit per color amount. Also, you can change color mode of PSD File, for example change from CMYK color to RGBA Color reduces the PSD file size. This app used not-documented features of PSD format, so the final result can be broken. Please use PSD File Reduce only if you clear know what you want to archive.
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
