There are many advantages to using PDF documents, the main one being the ability to password protect the document compared to other image files such as TIFF or JPEG. For important file protection or file copyright and other security considerations, encrypting PDF files is the safest choice. If you password protect a PDF file, you can restrict other users from copying, editing, or accessing the document, and in some cases prevent users from printing the file.
There are two types of encrypted PDF files:
● One is a file locked by the user, which means that you need a password to browse the content of the file. This kind of encrypted file is generally difficult to crack, and professional cracking software is required, and it may not be successful;
● The other is owner lock, which means you need to know the password to copy, print or modify the content of the PDF file.
Sometimes we forget the password or the PDF downloaded from the Internet is password-protected. In addition to entering the password to open it, you can also use some tools to crack the PDF password. The following will introduce three methods to clear the PDF password.

After cracking a PDF file, you can edit, modify or print it. Renee PDF Aide can provide functions of splitting, merging, rotating and watermark editing. Please refer to the introduction below for specific operations.
● Split PDF files
If your PDF file is too large or has unwanted content, you can split it. With Renee PDF Aide Converter software, you don’t need to convert it to other editable file formats and then split it.
The specific operation steps are as follows:
① Open Renee PDF Aide, click “PDF Toolset” > “Add File” to import the PDF file.
② In “PDF Toolset”, click “Split”. You can choose to “Split into multiple smaller files” or “Keep specified pages”.
③ Finally, click “Convert” to save it to the specified location.
● Merge PDF files
When you have multiple related PDF files, you can choose to merge them into one file. The merging method is very simple, and can be realized with one click through the Renee PDF Aide tool.
The specific operation steps are as follows:
① Open Renee PDF Aide, click “PDF Toolset” > “Add File”, and import the PDF files to be merged.
② In the “PDF Toolset”, click “Merge”, and you can choose to merge all pages or select some pages to merge. After selecting the ranges to merge, click “Convert” to save them to the specified location.
● Rotate PDF files
If there is an error in the PDF file you downloaded from the Internet, the content of the entire PDF page has been rotated. In order to read it normally, you need to rotate it to a normal angle.
The specific operation steps are as follows:
① Open Renee PDF Aide, click “PDF Toolset” > “Add File”, and upload the PDF file.
② Click “Rotate” and select the angle you want to choose, such as 90, 180 or 270 degrees. Also, you will need to choose which pages to select, all pages or some pages.
③ Finally, click “Convert” to save it to the specified location.
● Add watermark to PDF files
In some important documents, in order to protect the content of the document from being stolen, we usually need to add an exclusive watermark to the PDF file to indicate the source or owner of the document.
The specific operation steps are as follows:
① Open Renee PDF Aide, click “PDF Toolset” > “Add File”, and upload the PDF file.
② Click “Watermark”, please select “Add Watermark (cover surface)” or “Add Background”. This means whether the watermark floats above the text, or is added to the bottom of the text.
③ Select the watermark file to be imported, and click “…” in the “Watermark File” column to open the watermark file.
④ Select the page to be modified, all or part of it. Finally, click “Convert” to save it to a specified location.
If you know the PDF password, you can use Google Chrome to clear the PDF password. If you do not know the password, please use Method 1 to crack the password. Google Chrome has a built-in PDF reader and PDF editor, so you can open PDF files without using additional plug-ins. After opening an encrypted PDF file in the Chrome browser, you can save it as a PDF file without password protection, which will clear the PDF password.
Note: Google Chrome cannot crack all encrypted PDF files. It is recommended to use method 1 to crack.
The specific operation steps are as follows:
① Download and install on the computer and open the Chrome browser, drag the PDF file to be decrypted into the browser.
② Before opening the PDF file in the Chrome browser, you will be prompted to enter the PDF file password, and the file will be opened after the correct input.
③ For a Windows computer, please press the “Ctrl+P” keys on the keyboard at the same time; for a Mac computer, press “Command +P” to bring up the print menu. If the print menu cannot be brought up, it proves that the Chrome browser cannot decrypt the PDF file.
⑥ In the drop-down menu of “Target Printer”, select “Save as PDF”, and then click “Save” to save it to a new location.
After completing the above operations, the encrypted PDF file will be saved without a password, and you can open it directly without a password.
In addition to the above two cracking methods, you can also crack PDF passwords through online cracking tools. You don’t need to download software any more when you use the online cracking tool, and you can do it directly on the web page, but there are some obvious disadvantages when using the free online cracking tool. First of all, most of these free cracking tools will limit the size of uploaded PDF files, such as files cannot exceed 100MB or 20MB. In addition, if you want to process multiple PDF files at the same time, you will need to ensure a high-speed network connection, otherwise it will take a long time.
You can use the following online PDF password cracking sites:
If you want to use the online PDF password cracking tool, please follow the steps below to crack it:
① First, open the browser on the computer and visit the above-mentioned website for cracking PDF passwords.
② Click the “Choose File” or “Open File” button (button labels may vary by site). The Open dialog box will appear.
③ Select the PDF file whose password you want to delete.
④ Click “Unlock” or “Reset”, and wait for the cracking to complete.
