How to Remove a Password from a PDF on Mac

Important: this guide is about removing passwords you know

Before diving in, a critical clarification: every method in this guide requires you to know the existing password. This is not a guide about cracking, bypassing, or breaking PDF encryption. If you do not have the password to a PDF, these methods will not help you - and that is by design. PDF encryption exists to protect documents, and any legitimate tool will require authorisation before removing that protection.

There are plenty of legitimate reasons to remove a password from a PDF you own or have authorisation to modify. Maybe you password-protected a file before emailing it, and now you want to store the unprotected version locally for easy access. Perhaps a colleague sent you a protected PDF with the password, and you need to merge it with other documents that require an unlocked file. Or you might have a batch of old files with a password you set years ago that no longer serves a purpose.

Whatever your reason, the process is straightforward as long as you have the password. This guide covers three ways to do it on macOS, with an honest look at the trade-offs of each approach.

Method 1: Using Paradise PDF (recommended)

Paradise PDF is a native macOS application with a dedicated unlock tool that removes passwords from PDF files quickly and privately. It handles both user passwords (open passwords) and owner passwords (permissions restrictions) in a single workflow.

How to remove a password from a PDF with Paradise PDF

1. Open Paradise PDF and select the Unlock tool from the sidebar. The interface is clean and purpose-built for this task - no menus to dig through.
2. Add your protected PDF. Drag and drop the file from Finder or click the add button to browse. Paradise PDF will detect the type of protection on the file automatically.
3. Enter the password when prompted. If the PDF has a user password (open password), you will need to provide it before the file can be decrypted. If it only has an owner password (permissions restriction), Paradise PDF will identify the restriction type.
4. Click Unlock. Paradise PDF decrypts the file and creates a new, unprotected copy. The original password-protected file remains untouched, so you still have the secured version if you need it.
5. Choose where to save. Pick your save location and filename. The unlocked PDF is a standard, unrestricted file that you can open, edit, merge, split, or process with any other tool.

Why this method works best

Paradise PDF handles the full range of PDF protection scenarios. Whether the file has a user password, an owner password, or both, the unlock tool removes all restrictions in one step. You do not need to figure out which type of protection was applied or use different workflows for different protection types.

The decryption runs entirely on your Mac using native macOS APIs. This matters because the whole point of unlocking a PDF is to access its unprotected contents, and you do not want those contents passing through a third-party server during the process. With Paradise PDF, the encrypted file goes in, the decrypted file comes out, and nothing leaves your machine.

Batch processing is also supported. If you have a folder of password-protected PDFs that all use the same password, you can unlock them all at once rather than repeating the process for each file. The app is built in Rust, so the decryption is fast even for large, heavily encrypted documents.

Paradise PDF also preserves the structure and formatting of the original PDF during unlocking. Bookmarks, form fields, annotations, layers, and embedded fonts all come through intact in the unlocked version.

Method 2: Using macOS Preview

Preview can remove a password from a PDF, though the workflow is not immediately obvious. It works by opening the protected file with the password and then exporting an unprotected copy.

How to remove a password with Preview

1. Open the password-protected PDF in Preview. You will see a password dialog - enter the correct password to unlock the file for viewing.
2. Go to File → Export as PDF. This is the key step. Do not use "Save" or "Save As" - you specifically need the "Export as PDF" option.
3. Make sure the "Encrypt" checkbox is unchecked. In the export dialog, look for the Encrypt option. If it is checked, uncheck it. This tells Preview to create the exported copy without any password protection.
4. Choose a save location and filename, then click Save. Preview creates a new, unprotected copy of the PDF.

The limitations you should know about

Preview's approach works for removing user passwords (open passwords), but it has significant limitations. The most important one is that it may not fully remove all owner password restrictions. If a PDF has permissions-level restrictions (like preventing printing or text copying), Preview's export process does not always strip those cleanly. You might end up with a file that still has some restrictions embedded in its metadata.

The workflow is also unintuitive. There is no "Remove Password" or "Unlock" option anywhere in Preview's menus. You have to know that the trick is to export as a new PDF without the encrypt checkbox. This is not documented well in Apple's own support pages, and many Mac users never discover it.

Preview also cannot batch-process files. If you have ten protected PDFs to unlock, you will need to open each one individually, enter the password, export it, choose a location, and save. For a single file, this is manageable. For a batch, it becomes tedious quickly.

There is also a subtle risk with the save behaviour. If you accidentally use "Save" instead of "Export as PDF", you might overwrite the original protected file or trigger unexpected behaviour. Always use "Export as PDF" to create a separate, clean copy.

Method 3: Online PDF unlock tools

Several websites offer PDF password removal through a browser, including iLovePDF, Smallpdf, PDF2Go, and others. You upload the protected PDF, enter the password, and download an unlocked version.

How online tools typically work

1. Visit the website and navigate to their unlock or remove password tool.
2. Upload your protected PDF. The encrypted file is transferred from your Mac to the service's servers.
3. Enter the password. You type the PDF password into the website, which the server uses to decrypt the file.
4. Click Unlock and wait for the server to process the file.
5. Download the unprotected PDF. The decrypted file is downloaded back to your Mac.

Why this approach has serious privacy implications

Using an online tool to remove a PDF password means sending both the encrypted file and its password to a third-party server. Think about that for a moment. You are handing over the locked document and the key to unlock it to a company you do not control. The server now has full access to the unprotected contents of your file.

This is arguably worse than uploading an unprotected file, because the fact that you password-protected it in the first place suggests the contents are sensitive. Tax returns, legal agreements, medical records, financial statements, confidential business documents - these are exactly the kinds of files people password-protect, and exactly the kinds of files you should not be uploading to random websites.

Even assuming the service is trustworthy and deletes your files promptly, you have no way to verify that. Server logs might record the password. Backup systems might retain the decrypted file. Employees might have access to processed documents. And the upload itself could be intercepted on an unsecured network, exposing both the file and its password in transit.

Beyond privacy, online tools have the usual practical limitations: file size caps (typically 25-100 MB), daily usage limits on free tiers, slower processing due to upload and download times, and complete unavailability when you are offline. Some services also struggle with strongly encrypted PDFs or files with complex permission structures.

Understanding what gets removed

PDF files can have different types of protection, and it helps to understand what each method actually removes:

User password (open password)

This is the password required to open and view the PDF. When you remove it, the file becomes freely accessible to anyone. All three methods in this guide can remove user passwords, though they all require you to enter the correct password first. Without the password, the file's contents remain encrypted and inaccessible.

Owner password (permissions password)

This controls what actions are allowed on the PDF - printing, copying, editing, annotating, and extracting pages. Removing the owner password lifts all restrictions, making the PDF fully editable and extractable. Paradise PDF removes these cleanly. Preview's results can be inconsistent. Online tools vary.

Digital signatures and certificates

Some PDFs are protected with digital certificates or signed with digital signatures. These are different from password protection and are not covered in this guide. Removing or altering a digital signature changes the document's verification status and may have legal implications.

Common scenarios for removing PDF passwords

Archiving documents locally

You received a password-protected PDF via email and now want to save it to your local archive without the hassle of entering a password every time you open it. Since the file is stored on your own machine and not being shared further, the password no longer serves a purpose. Remove it and save the unlocked version to your archive.

Merging protected PDFs

You need to combine several password-protected PDFs into a single document, but the merge tool requires unlocked files as input. Unlock each PDF first, then merge the unprotected versions. Paradise PDF can handle both the unlocking and the merging.

Editing a protected document you created

You password-protected a PDF before sending it out, and now you need to edit the original. Rather than working around the restrictions, simply unlock your own file, make your edits, and re-protect it if needed.

Printing a restricted PDF

The PDF has an owner password that prevents printing, but you have legitimate access and need a hard copy. Removing the owner password lifts the printing restriction. You will need the owner password to do this - if you only have the user password, you can view the file but not change its permissions.

Comparison: All three methods side by side

Here is how the three approaches compare when you need to remove a password from a PDF on Mac:

When to use each method

Use Paradise PDF when...

You need to reliably remove both user and owner passwords, the document contains sensitive information, you have multiple files to unlock, or you want to preserve the full structure of the original PDF. It is the best option for anyone who handles protected documents regularly - especially professionals dealing with confidential client files, legal documents, or financial records.

Use Preview when...

You need to quickly remove a simple open password from a single PDF, the document is not particularly sensitive, and you do not need to remove permissions restrictions. Remember to use "Export as PDF" rather than "Save", and check that the exported file does not retain any unwanted restrictions.

Use online tools when...

The document contains absolutely nothing confidential, you are on a machine where you cannot install software, and you need a one-off unlock. Be aware that you are sending both the file and its password to a third party. If the document was worth password-protecting, it is probably worth unlocking privately.
