Authorities said 95 suspects have been charged with possessing, distributing or producing illegal content, while courts ordered 47 of them into pre-trial detention.
Police said some of the seized material included content generated using artificial intelligence, such as images styled on Japanese comics.
"The results of Operation Hellfire show once again that there is no tolerance for the sexual exploitation of children or the distribution of such material, including content created using AI," said Wojciech Olszowy, head of the cybercrime bureau.
He added that the primary goal was to stop abuse and hold perpetrators accountable.
Investigators said those detained include a teacher accused of recording students at a language school, a man who allegedly contacted children through a messaging platform and coerced them into sexual acts, and two men suspected of secretly filming family members and others in private settings.
Police also detained a 19-year-old man suspected of recording sexually explicit material involving his underage stepsister, according to preliminary findings.
The operation was coordinated with the National Public Prosecutor’s Office and involved around 500 officers from cybercrime units, regional police forces and a police anti-trafficking division, with support from military police.
Operation Hellfire is the eighth such crackdown targeting child exploitation carried out by the bureau, according to officials.
Previous operations have resulted in nearly 6,500 searches, charges against 477 people and the seizure of more than 2.5 million illegal files.
Data from the Internet Watch Foundation, a Britain-based organisation that aims to combat online child sexual abuse, shows Poland ranks among the top 10 countries globally for reports of such material, accounting for about 3 percent of cases worldwide.
