Testimonials from Our Customers

We use easyPDF SDK technology for PDF conversion and it works very well. We knew BCL is a solid company. We have also looked at several competitors and tried to use their products, but we like easy PDF SDK the best. When we talked to BCL Technologies’ design engineering team, we knew they had the knowledge and confidence to solve our problems.” Read the case study

We evaluated many PDF tools and drivers. We even wrote our own. Except for BCL’s easyPDF SDK, all had limitations we couldn’t live with. Some only converted from MS Office and not very well. Others could not do annotation or text stamping on PDF documents. None were as easy to use and as easy to integrate.” Read the case study
