How to Unlock PDF password

Hello,

If you're trying to load a password protected PDF using our SDK, that can be done in a few ways:

• Using our RasterCodecs load options:

  Code:

  
  // For example:
  rasterCodecs.Options.Pdf.Load.Password = "some password";
  

  
  
• Using our document SDK load options:
  
  • .NET: https://www.leadtools.com/help/leadtools/v20/dh/dox/loaddocumentoptions-password.html
    
  • JavaScript: https://www.leadtools.com/help/leadtools/v20/dh/javascript/dox/loaddocumentoptions-password.html
    

If this wasn't what you were wanting to do or you have any further questions, please let me know.

Thanks,

nice info

In the last month, I was also having issues unlocking my PDF password-protected file, I tried several tools to solve the problem but using multiple software causes my device to slow down while unlocking the PDF, and some of them take a long time to install and do not work properly because they remove some of the content from the PDF file. So, following my friend's recommendation, I switched to OSTtoPSTAPP PDF Unlocker Software and used it. Fortunately, this application works and is easy to install. This program protects the PDF's integrity and attachments while unlocking the PDF file. It also allows me to specify the location of the unlocked PDF document. This tool performs its tasks safely and error-free.
