"I'm a freelance illustrator, and I send PSDs to clients for feedback. But they can't always open them. reaConverter converts my PSDs to PDF with embedded layers, so they can view and comment without Photoshop. It's made client collaboration so much smoother."

"ReaConverter's batch conversion of PSD to WebP is a lifesaver for my e‑commerce site. I take product mockups in PSD and convert them to lightweight WebP images for faster loading. The quality is amazing, and the compression is aggressive but clean. Highly recommended for online stores."

"I had a huge PSD archive from an old project that I needed to convert to TIFF for printing. reaConverter preserved every layer and adjustment – the output was identical to the original. I've tried other converters, but they always flatten or lose quality. This one is the real deal."

GP4 to PSD Conversion: FAQ

What are GP4 files?

GP4 is an image extension included in the CALS group of formats. CALS (Continuous Acquisition and Life-cycle Support) represents an initiative undertaken by the Department of Defence in the United States in the 1980s, with the aim of creating a standard for storing and linking military data. Similar formats include CG4, CAL and CALS. Most formats that are part of the CALS group are currently considered rare and obsolete.

What are PSD files?

PSD is the default format for handling images using Adobe Photoshop and it represents a layered image file. PSDs allow later editing of available layers, including transparency, masks, alpha channels and texts, among others. After applying all desired editing, PSD files can be saved in Photoshop under more easily recognizable formats, such as JPEG or PNG, which are also smaller in size but flatten the image and hence do not allow later editing of layers.
