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.

Clients kept asking to ‘just peek’ at my layered PSDs. Now I convert them to locked PDFs with reaConverter before sending. No more ‘accidental’ edits from ‘helpful’ clients!

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.

FAQ

CS1 to PSD Conversion

What are CS1 files?

CS1 is a RAW image format associated with CaptureShop, a program used for editing and organizing photographs shot with Sinar cameras. Sinar cameras are large or medium sized and are generally preferred by professional photographers. The main advantage of shooting in RAW mode with such a camera is the possibility to customize the image as desired during digital post-processing.

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.
