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.
