We faced a massive challenge: digitizing 20 years of CGM archives into PNG format. Initial estimates projected months of work, but reaConverter's powerful batch processing and resolution scaling let us complete the project in weeks. Most impressively, it handled even our pre-1994 vector files flawlessly—zero errors, perfect fidelity.

FAQ

PRT to CGM Conversion

What are PRT files?

PRT is a file extension used by several unrelated formats. Most often it is a part file of a CAD program, a drawing or a 3D model of one component, created in Siemens NX, CADKEY, MegaCAD, or ProCAD. It can also be a print file with commands for a printer or plotter, or a raster picture in CMYK colors prepared for printing. Programs from different developers cannot open each other's PRT files, so it is important to know which program created the file.
