If you have a bunch of PDF files with long and complex passwords. You know how depressing and inconvenient it is to enter a password every time you open a PDF file. (For example, I am using the Kindle 5 without a keyboard)
"Is there no tool to delete the PDF password ?" One day, someone asked me this question on Twitter. The answer is obviously yes!
Remove PDF File Password
There is a free tool named becypolicmetaedit that can help you remove the PDF File Password * without changing any other file content. (I'm not sure why developers need to give such a complicated name to such a useful tool ).
Below is what you want to do:
1. Run thisProgramIt will ask about the location of the PDF file.
2. Before you select and open the document, you need to change the mode to "complete rewrite (full rewrite )".
3. Jump to the security label and set "security system" to "no encryption (not encrypted )". Click Save to save your PDF file.
More information? Click the details navigation bar of the PDF tool.
