Big Filter Software

For decades, we have developed software tools in-house to support our own operations, refining them over years of real-world use. These applications were built to solve practical challenges, improve efficiency, and meet the high standards required in our industry. As technology evolves and our systems mature, we are now beginning to release certain components that may also be valuable to others. While these tools were originally created for internal purposes, we believe they can benefit the broader community, and we are pleased to make them available free of charge as we gradually share more of our work over time.

Currently, we are offering our PDF Toolkit, a versatile application designed to handle various PDF-related tasks.
