"Security was our top concern when evaluating file conversion tools. reaConverter’s offline mode and role-based access controls let us lock it down for sensitive environments. No unexpected network calls or bloat — just clean, fast conversions. Even passed our pen-testing scans without a hitch."

CPT to STP Conversion: FAQ

What are CPT files?

The CPT file extension is associated with Corel PHOTO-PAINT, a raster graphics editor developed by Corel. CPT files use Corel PHOTO-PAINT's own bitmap format to store edited digital photos. In other words, they are graphic files with distinct layers, alpha channels and transparency, all of which allow for future image editing. CPT is very similar to the TIFF format in terms of image quality and size, but the latter tends to be more popular and easier to handle using regular image viewers.
