In this article, I will show you one method of extracting text from password protected PDF file directly. In the market including VeryPDF, there are many desktop version software can help you make it. However, in this part we will try to make it by cloud based application.
Different with the traditional desktop software, cloud based application can help you make it in the shortest time and the easiest method. The software I will use is named as PDF to Text Converter Cloud API.

Extract text from PDF by cloud based API application.
- In the above part, I say the cloud based API can give you the easiest method to run the conversion because by the API you do not need to download any application. The conversion of API runs within browser, so simply open any browser and input URL following the below URL then conversion could be done.
- Here is an example for your reference:
By the above URL, we can extract text from PDF . Please pay attention to the structure of the URL. It is quite easy, when you run the real conversion, please replace PDF URL to the real URL of the PDF you need to convert. Change the API code to the real one if you have. At the end of the URL, please specify the PDF password following parameters. The parameters I used in above URL are here:
- When conversion finishes, there will be a text URL showing in the new tab. Please copy and paste it to the browser then you will see all the text part showing in the browser directly.
- If you do not need to view text file in browser, you can download it directly to your computer.
-opw <string>: owner password (for encrypted files)
-upw <string>: user password (for encrypted files)
Please note when processing only owner password protected PDF file, you do not need to input password at the end of the URL as this software can process this kind of password protected PDF automatically.
By this method, we can extract text from PDF free. By the API version, there is no using time limitation. During the using, if you have any question, please contact us as soon as possible.
