If you still had a rough impression of the password, then go with Brute-force with Mask Attack.
Step 4: Next, just click 'Start' icon to begin the recovery process. Your password will be displayed once it's recovered. Just copy it and open your PDF document with it.

Most of the PDF password removal tools only works for permission password. If you want to remove open password for a PDF file, you can try using an open-source utility like Hashcat. Be warned, however, that this is not for newbies and requires some amount of experience working with command-line utilities. The steps are broken down into hash extraction and password recovery and are outlined below.
To extract the hashes, you can use a program like pdf2john.py to extract and store (dump) the hash into a separate file. This file can be used in the next step to recover the password. Run the command shown below in Terminal on your Mac.
Step 1: Visit pdf2john.py page and click RAW button to open the text page. Click Ctrl + s to save the .py on your Mac.
Step 2 : Create a new folder on Desktop and copy pdf2john.py file as well as the password protected PDF file to it.
Step 3 : Open Terminal app on Mac and go to the new folder via 'cd' command. Then type the following command to extract the hash file from PDF:
python pdf2john.py test.pdf > test.hash
Step 4 : Download Hashcat binaries from its website and unzip the files. You will get a list of executable files. For macOS, it is hashcat-cli64.app. If there is no such an file in the folder, please try to install hashcat (brew install hashcat) on Mac via homebrew.
Step 5: Now copy test.hash file to Hashcat folder and type the command in Terminal to start cracking PDF password from given hash file generarated in above step.
Note: This command has several parameters that you need to specify, so follow it carefully.
Step 6 : Once the recovery process is successful, you'll see an output like this:
The password in this instance is 1806, which you can see in the screenshot above. Use that to open the PDF file. Unfortunately, Hashcat is not very good with long and complex passwords, and it could take several hours or even days to crack such hashes. You can also consider using the next utility shown below.

Although all the tools described until now are quite effective at what they do, you might not want to install anything on your Mac for this purpose. If that's the case, you can consider this next method, which uses an online service to remove forgotten password from PDF files..
The website (Onlinehashcrack.com) is purely a password cracking service for security experts and IT professionals. It's very simple to use but it does have a file size limit of 400MB. That's pretty good for most PDF files except really large documents. Here's how to do it:
Step 1: Go to the onlinehashcrack website and click on 'Browse' on the right side to upload your file. You can also copy the hash value from the hash file we described in Method 1 from the leftside options.
Step 2: Enter your email ID in the text field below that and hit the 'Submit' button. The cracked file will be emailed to that address when it's ready.
The only problem with this service is that it is free for simple passwords or those that are found in standard word lists; however, if you're using a custom word list or need to use Brute Force because the password is complex, the site charges $9 an hour. If your password takes a day to crack, it could cost as much as $200 or more.
All of these tools are great at what they do, but we recommend using PassGeeker for PDF because of its easy-to-use interface, speed, and its ability to handle any type of Open or permissions password. This is currently the best way to remover password from PDF on Mac.
