PSD (Photoshop Document) file format is an image file created by Adobe Photoshop, a professional image-editing program. PSD may include image layers, adjustment layers, layer masks, annotation notes, file information, and other Photoshop-specific elements.
To view and edit .psd files, we need Adobe Photoshop but here is a simple and small tool which lets you easily view PSD files without needing Photoshop.
PSD viewer is a free and handy tool to open PSD image files. It can easily convert and save opened image in other file formats as JPEG, Bitmap, GIF, PNG and other extensions. PSD viewer supports resizing of PSD images, enlarge or reduce, without losing any quality. It also has options to zoom, rotate and resize .psd images.
– Supports All Windows [Requires Microsoft .NET Framework 3.5]
GIMP is another better alternative to view PSD files.
