Every one is aware that you can secure PDF file by password, so only authorized users can read and access the data contained within the document. This is fairly common with everything from contracts to accounting and financial records, and it’s equally common to sometimes require the removal of the password encryption from that same PDF document
To remove the password from a PDF file on the Mac, you will use the same OS X Preview app that can be used to secure the PDF with a password. Simply follow the steps given below
- Open the encrypted PDF file into Preview and enter the password to get access to the document. First you have to unlock the document to be able to remove the password from the PDF file, the file is encrypted and it is not possible to do so without (at least for most users).
- Choose the file menu and select save as.
If you save over the existing file it will remove the document, otherwise saving as a new file name will create a new secondary PDF file without the password protection. Re-saving secured PDF without the encrypted password will completely remove the password from the new document, allowing it to be sent and viewed as normal without password entry.
In a similar manner, you can use this trick to change a password on a protected PDF file too, simply by saving the file without a password, then re-saving it yet again with a new password. That may sound like a bit of work, but it’s a quick process, and certainly beats sharing a primary password with other users if you happened to have set one that wouldn’t be appropriate to share.
