TEXTfromPDF is marketed as shareware. As such, you are entitled to freely try out the software for a period of 20 days. The 20 day period represents days of actual usage rather than consecutive calendar days. This will allow you ample opportunity to test TEXTfromPDF. At the end of the 20 day trial period you must purchase a license to continue using it.
During the trial period you will be able to test out the full functionality of TEXTfromPDF with some slight restrictions:
1) Only the first 10 pages of the PDF Document(s) will be processed.
2) Watermark text will be added to the beginning and end of each of the output text files. The watermark text will state that the file was created using an unlicensed version of the product.
These limitations can be removed by purchasing a license.
