Tool Introduction
"Remove PDF Password" is an efficient and convenient online tool specifically designed to remove the "open password" from PDF files. If you have a PDF document that requires a password to open, whether it's an important report, invoice, or contract, this tool can help you quickly remove its opening restrictions, allowing you to access the file content without entering a password every time. This tool only supports removing passwords that prevent file opening; it does not currently support removing "permission passwords" that restrict editing, printing, or copying.
How to Use
- Upload Encrypted PDF File: Click the "Upload Encrypted PDF (20MB only)" area, select the PDF file from which you want to remove the password, or drag and drop the file directly into this area. Please note that the size of a single file cannot exceed 20MB.
- Enter PDF Open Password: If your PDF file requires a password to open, please enter the correct original password in the "PDF Open Password" field. If your PDF does not have an open password, or if you are unsure, this field can be left blank.
- Start Removal Process: After confirming that the file and password (if any) are correct, click the blue "Remove Password" button. The system will begin processing your file.
- Download Password-Free PDF: Once processing is complete, you will see the original file name, size, and a downloadable "Converted File" link in the result area. Click the link to download the new PDF file with the open password removed.

Frequently Asked Questions
- Q: What input formats are supported? A: This tool currently only supports
.pdf format files as input.
- Q: What is the output format? A: After successful processing, the output result is still a
.pdf format file, but the open password has been removed.
- Q: Can this tool remove all types of PDF passwords? A: No. This tool is primarily used to remove the "open password" of a PDF, which prevents users from opening the PDF file. It does not currently support removing "permission passwords" that restrict editing, printing, copying, or adding annotations.
- Q: What if I don't know the PDF's open password? A: Unfortunately, if the PDF file has an open password and you cannot provide the correct original password, this tool cannot forcibly remove its protection. You must provide the correct original open password to successfully decrypt it.
- Q: Is there a file size limit for uploads? A: Yes, the size of a single PDF file cannot exceed 20MB.
Important Notes
- Password Type: Please be clear that this tool only removes the "open password" of a PDF. For PDF files with "permission passwords" set to restrict editing, printing, or copying, this tool cannot remove these permission restrictions.
- File Size Limit: To ensure service quality and processing efficiency, the maximum size for a single uploaded PDF file is 20MB. Please ensure your file meets this requirement.
- Password Accuracy: If the PDF file has an open password, please make sure to enter the correct original password. Incorrect passwords will lead to decryption failure. If the PDF does not have an open password, please leave the password field blank.
- Data Security: We are committed to protecting your file security. All uploaded files are used solely for processing and are deleted according to our privacy policy after processing is complete.
Types and Uses of PDF Passwords
PDF files typically have two main types of passwords, each with different functions and protection purposes:
- Open Password (User Password): This is the most common password type, used to restrict access to the PDF file's content. Users must enter the correct open password to view and read the PDF document. This "Remove PDF Password" tool primarily targets this type of password for removal.
- Permission Password (Master Password/Owner Password): This password does not prevent users from opening and reading the PDF file, but it restricts users from modifying, printing, copying text or images, adding annotations, filling out forms, and other operations on the file content. Even if the open password is entered, if the file also has a permission password set, these operations may still be prohibited. This tool does not currently support removing this type of permission password.
Understanding the difference between these two types of passwords will help you better use PDF tools and manage your document security.
