how to edit a locked pdf

To edit a locked PDF, you first need to identify what kind of restriction it has, as some PDFs are protected with a password, while others limit editing, printing, or copying.

If you know the password, you can simply enter it after opening the file in PDF.net and edit it directly, or copy and paste the content into a Word file for further editing. If you don’t know the password, you will have to use specialized software.

In this article, we will delve further into the different types of PDF restrictions, ways to work around them, and common problems you might encounter when troubleshooting the issues.

What Does “Locked” Mean in a PDF?

In a PDF, “locked” means there are restrictions preventing you from fully accessing or editing the file.

However, not all locked PDFs are the same; generally, there are password-protected PDFs and permission-restricted PDFs.

  1. Password-protected PDFs require you to enter a password before you can open the file. This is the strongest form of locking because, without the correct password, you can’t even see the content. When you password-protect a PDF, you keep sensitive information secure from unauthorized viewers.
  2. Permission-restricted PDFs, on the other hand, allow you to open the file but restrict certain actions like printing, copying text, editing, or adding comments. These restrictions are set by the person who created the PDF to control how the content is shared.

PDFs are usually locked to protect sensitive data such as contracts, medical records, or financial documents. Copyright protection is another common reason for doing so since publishers may lock PDFs to prevent unauthorized distribution of their work. Finally, locked PDFs help safeguard sensitive information so that only authorized users can access the content.

Types of Restrictions

The types of restrictions often used for secured PDFs are:

  • Printing restrictions, which prevent users from printing the PDF or limit the number of pages they can print.
  • Copying restrictions, which keep users from copying and pasting the PDF’s content.
  • Editing restrictions that block any changes to the document, such as direct typing, highlighting, or adding fillable fields.
  • Commenting restrictions, which stop users from adding, editing, or deleting comments and annotations.
  • Form-filling restrictions that disable the ability to fill out form fields within an interactive PDF.

How to Edit a Locked PDF

To edit a locked PDF, you can either unlock it by entering the password if you have it or use specialized tools to remove restrictions if you don’t. Once you unlock your PDF, you can edit it, or convert it into a .docx file and make changes in Word.

Edit a Locked PDF if You Know the Password

Editing a locked PDF is easy if you know the password. To do so, follow these steps:

  • Open PDF.net, hover over More tools in the header, and choose Unlock PDF.

Edit a Locked PDF if You Don’t Know the Password

If you don’t have the password, your options to remove PDF passwords online are more limited and complicated. Some third-party tools can remove PDF restrictions or unlock permission-protected files.

However, you need to be cautious when choosing these, as it is important to select reputable ones to avoid risks such as data theft. Also, keep in mind that removing a PDF password online without permission can violate copyright or privacy laws, so having permission is essential.

Convert the PDF to Another Format

Converting the PDF format to another format, such as .docx, is another way to edit the content of your file, and PDF.net comes in handy for this as well. However, keep in mind that you still need to unlock your PDF using one of the two methods above first.

Here’s how to convert your PDF to Docx:

Open the PDF-to-Word converter tool and upload your file
  • Select DOCX and click Convert to DOCX.

Once converted, you can change the text as needed and then save the file as a PDF again to keep the formatting intact.

Is It Legal to Edit a Locked PDF?

It is legal to edit a locked PDF when you have the proper rights to do so. For example, if you are the owner or have been given explicit consent by the owner, unlocking and editing the PDF is perfectly fine.

However, editing a locked PDF without permission may violate copyright laws, terms of use, or confidentiality agreements. If the document contains protected intellectual property, sensitive information, or is clearly marked as restricted, bypassing its security can be illegal. When in doubt, it is best to seek permission or legal advice to avoid potential issues.

3 Common Issues When Unlocking PDFs

There are three common issues that you might encounter when unlocking PDFs, and they are as follows:

#1. Incorrect Password

Many unlocking attempts fail simply because the password is incorrect. PDF passwords are case-sensitive and must be exact, including any special characters or spaces. So, if you mistype the password or use an outdated one, the PDF will remain locked.

This problem also often happens if the document owner has given you the wrong password by mistake or changed it to another one. Unfortunately, there is no way to guess or bypass a password-protected PDF without the correct one, so you will need to double-check your entry and verify the password with the source if possible.

#2. Corrupted File

A corrupted PDF file can also cause unlocking problems. Corruption can happen while downloading, saving, or transferring the document. It can damage the file so it won't open properly or accept the password.

When a PDF is corrupted, your viewer software might crash or fail to unlock it. In these cases, even having the right password won’t help. Repairing a corrupted PDF requires using specialized recovery tools or obtaining a fresh copy from the document owner.

#3. Unsupported Encryption Type

PDFs can be secured with different levels of encryption, some of which are more complex than others. If your unlocking software doesn’t support the encryption type used on the PDF, it won’t be able to remove the restrictions or open the file.

This often happens with proprietary encryption standards, which are usually adopted by businesses, legal firms, and government agencies. To solve this, you may need to use more advanced software, update the one that you are using, or use the official software that created the PDF.

Unlock and Edit Your PDFs with Ease

If you have the password, PDF.net lets you quickly unlock your document for easy editing. You can choose from the editor’s full suite of tools to insert images, reorder or remove pages, add annotations, and make other changes to customize your document exactly how you need it.

Final Thoughts

The key to editing a locked PDF is matching the method to the situation. When a password is available, unlocking is quick with a password-protected PDF editor; meanwhile, without the password, third-party services can be an effective workaround.

Regardless of the method, remember to always keep legal and ethical considerations in mind, especially when handling sensitive files. This way, you protect both the content and yourself.

How to Edit a Locked PDF FAQs

#1. How do I edit a PDF that doesn't allow editing?

To edit a PDF that doesn’t allow editing, you can unlock it with the correct password using PDF.net and then edit it directly there. Alternatively, you can copy and paste the PDF’s content to Word, make your changes, and then save it back as a PDF.

#2. Will unlocking a PDF damage the file?

Unlocking a PDF will not damage the file if you use reputable software. There shouldn’t be any missing text issues, though some complex elements may shift slightly when using certain third-party tools or during conversions.

#3. What’s the difference between a locked and an encrypted PDF?

The difference between a locked and encrypted PDF is that a locked PDF has restrictions on actions like editing or printing, while an encrypted PDF uses password-based encryption to prevent unauthorized access to its content entirely. Additionally, some PDFs can be both locked and encrypted.
