Two Types of PDF Protection: What Can Be Removed Instantly?

There are two fundamentally different forms of PDF protection. Understanding the difference can save you hours and help you choose the right tool.

Permissions Password — Remove editing/usage restrictions INSTANT

✅ Removed in 1–2 seconds without brute-force!

If a PDF opens without a password but you cannot:

  • Print the document
  • Copy text
  • Edit content
  • Extract pages or images

…then it has a Permissions Password (also known as the “Owner” password). Accent PDF Password Recovery instantly removes this protection, regardless of the password's complexity.

Document Open Password — REQUIRES BRUTE-FORCE

If the PDF won't open without a password, it's the Document Open Password (also known as the “User” password). This type requires testing possible passwords using a brute-force method.

Encryption Type PDF Version Recovery Techniques Recovery Feasibility
RC4 40-bit PDF 1.2 (legacy) Key extraction and decryption without password; brute-force if needed Guaranteed (outdated encryption)
RC4 128-bit PDF 1.3–1.6 Brute-force; GPU acceleration available Moderate (effective when the password is simple)
AES 256-bit PDF 1.7 EL3 Brute-force; increased speed due to a known implementation issue Above average (password hints recommended)
AES 256-bit PDF 1.7 EL3/EL5/EL7 and PDF 2.0 Brute-force with mask attack and dictionary mutation Low without hints (password structure knowledge is important)

💡 How to determine what type of PDF protection you have

Try opening the document normally:

  • The file opens, but actions are restricted → Owner password → Removed instantly
  • The file asks for a password before opening → User password → Requires password recovery (brute-force / masks / dictionaries)

Key Advantages

  • Support for Adobe PDFs (Acrobat 1.0 to Acrobat DC)
  • Recovery of PDF passwords with speed guaranteed to amaze (details)
  • Saves time during password search thanks to unique features
  • Best ratio of price to performance

Accent PDF Password Recovery supports all versions of the Adobe PDF format, successfully recovering passwords from documents written yesterday and from documents created ten years ago.

The program’s highly optimized source code is smart enough to know the strengths and special features of Intel and AMD processors, guaranteeing that it is a blazing-fast way to find PDF passwords on any computer.

By carefully tweaking the password space (the range of potential passwords to try), you can exclude massive ranges of potential passwords from scanning and speed up the process considerably.

The program's speed – giving some of the fastest results ever, according to testing results – and ability to restrict the password space make Accent PDF Password Recovery the best solution for finding lost passwords for PDFs.

Why Not Online Services? Risks for PDFs

Online services can be convenient in some cases, but they pose serious risks for sensitive documents, such as contracts, financial reports, medical records, and NDAs.

Comparison: Online Services vs Accent PDF Password Recovery

Criterion Accent PDF Password Recovery Online Services
(iLovePDF, SmallPDF, Sejda)
Data Security ✅ Everything runs locally on your PC
✅ Document never leaves your computer
❌ Document is uploaded to a third-party server
⚠️ Risk of sensitive data exposure
What Can Be Removed ✅ Owner password (permissions) instantly
✅ User password (document opening)
✅ Only Owner password (restrictions)
❌ User password not recoverable
Limitations ✅ No file size limits
✅ Unlimited usage
❌ File size: 5–50 MB
❌ Daily operation limits
Speed for User Password ✅ Depends on PDF version and PC performance ❌ Not supported
Cost From 40₽ for the first year $6–15/month subscription
or $10–20 per operation
Internet ✅ Not required (works offline) ❌ Always required

⚠️ Note: Uploading sensitive documents to an online service puts you at risk of losing control over your data. Even if the service promises to delete the files, they still pass through the service's servers and may end up in logs, backups, or databases.

Recommendation: Only use online services for public documents without confidential information. Always use local desktop solutions for business documents, contracts, and financial reports.

Diverse attacks

Accent PDF Password Recovery offers three methods for password recovery: brute force, attack by mask, and attack by dictionary. Each attack has plusses and minuses. Depending on the situation these types of attacks will have different success rates.

How to choose a password recovery method

Selecting the right method can significantly speed up recovery:

  • Use a dictionary attack if the password is based on words, names, dates, or their combinations. The program can check millions of options in minutes.
  • Choose a mask attack when you remember the password structure: length, positions of known characters, types of characters used (letters only, letters with numbers, etc.).
  • Brute-force attack — the last resort for short passwords when other methods fail. Start with the minimum length and increase gradually.

Pro tip: Start with faster methods (dictionary, mask with known parts) before moving to a full brute-force search.

PDF decryption

AccentPPR rescues your data that has been encrypted in PDFs in Adobe Acrobat 2–4 format (40-bit encryption). The program simply decrypts the password-protected file and creates an exact copy that does not have the password. The time needed to find the decryption key is always the same – it does not depend on the length or complexity of the original password.

Automatic password search

A special feature for beginners. The program evaluates the computer’s configuration and performance to automatically select the script that best balances search time and the number of passwords to try.

Advanced masking for brute force attacks

A special feature for professionals. The advanced mask support built into the program adds new features for creating sophisticated masks that can verify passwords and save time by omitting unneeded potential password candidates.

Macro language

A special feature for professionals. The built-in macro language describes the rules for mutating the passwords tried in dictionary-based attacks. This changes the shape and appearance of passwords, adding words and characters, combining passwords from several dictionaries, etc. Unusual passwords such as "pa55word" and "VeryStrongPassword1234" are found much more quickly.

How to purchase the Accent PDF Password Recovery

Frequently Asked Questions

Is it legal to use PDF password recovery software?

Yes, as long as you are recovering access to your own documents or have the legal right to access the file. Using the software to access someone else's documents without permission is illegal. Accent PDF Password Recovery is intended for legally recovering access to your own files.

Is my data safe when I use the software?

Absolutely safe. Accent PDF Password Recovery works entirely on your computer — no data is sent over the internet. Your document remains confidential and never leaves your PC. The program contains no spyware and does not collect any user information.

Does the software support the newer PDF versions (ISO 32000‑2 / PDF 2.0, Revision 6)?

Yes. Accent PDF Password Recovery supports all Adobe PDF versions — from Acrobat 2 (PDF 1.2, /R 2) up to the latest Acrobat DC revisions (PDF 2.0, /R 6). The program automatically detects the document’s PDF version and encryption type. As soon as you select the file, you’ll see the format version and protection details before choosing an attack method.

What if I only remember part of the password?

Use the program's powerful positional mask attack feature. Specify known and guessed characters for each position, and the program will test only the unknown positions under the given constraints. For instance, if you recall that the password begins with "company" and ends with "2024," the search time could be reduced by thousands or even millions of times.

Can a very complex password be recovered?

In theory, yes. In practice, it depends on several factors, such as the PDF version, the complexity of the password, and whether you have any hints. For example, a six-character password containing letters and digits for a PDF compatible with Acrobat 6.0 and later and later can be recovered in a reasonable amount of time, especially with GPU acceleration. However, the same password for a PDF compatible with Acrobat X and later may require years of computation due to slower validation, especially on CPU-only systems. In any case, Accent PDF Password Recovery provides a realistic time estimate based on your PC's specifications and the settings you choose to help you decide whether recovery is practical.

Most importantly, it offers assured security: no ads, malware, spyware, or uploading of your files to the internet.
