The many advantages of PDF files make it an important document format in everyday life and work.
Not only can it ensure that the format of the presented file content is consistent across different devices, but it also has an encryption function to prevent the content from being tampered with, which can better ensure the security of file data.
However, "encryption is easy to decrypt but difficult to decrypt", how can we ensure the integrity and accuracy of the content of the PDF file while decrypting it smoothly?
In fact, all you need is an excellent decryption tool to quickly unencrypt your files. Let me tell you how to decrypt encrypted PDF files!
1: Use WPS to complete PDF file decryption
Let's take a look at what to do.
When we use the software to open the encrypted PDF file, the password input interface as shown in the figure below will pop up, we only need to enter the open password, and then select "Confirm Password", and then we can open this PDF file smoothly.
If we want to completely undecrypt the PDF file, we need to click "Protect" - Document Encryption" after opening the file, uncheck the "Set Open Password" option, and then click "Confirm".
In this way, we have finished decrypting the PDF file.
2: Use the all-in-one PDF converter assistant to complete PDF file decryption
Let's take a look at what to do.
When we open this software, we need to swipe down the page, find the "PDF decryption" function in the "PDF function" category, click the button, and we can enter the corresponding function interface.
Or we can directly enter the words "PDF decryption" or "decryption" in the search box in the upper left corner, and we can also enter the PDF decryption interface. ）
Once in the interface, we can start uploading the PDF file that needs to be decrypted.
If it is the decryption of a single file, we can click "Add PDF file" to import it; If you need to decrypt multiple files at the same time, you can click "Add PDF Folder" to upload the entire folder, effectively avoiding the repeated operation of uploading files one by one.
After entering the open password and completing the import of the PDF file, we can click on the "Page Number Selection" option, select the pages in the file that need to be decrypted (if we do not need a local decryption service, we do not need to adjust this option), and finally select "Start decryption".
3: Use Google Chrome to complete PDF file decryption

Once we have finished importing the PDF file, we will only have to find the "Save as PDF" option in "Changes" to save it again.
These three methods are not difficult to operate, and the decryption effect is quite good, I believe that after you try it, you will soon be able to master the trick of decrypting PDF files, and no longer worry about how to decrypt encrypted PDF files.
