To unlock one you have the right to change, open it with the password and save a copy with the security turned off: in Adobe Acrobat, in Preview on a Mac, by printing it to a new PDF in a browser, or with `qpdf --decrypt` on the command line. If you have forgotten the open password, there is no legitimate shortcut. Disclosure: The Drive AI publishes this guide and makes free PDF tools at [thedrive.ai/tools](https://thedrive.ai/tools). None of them removes a password; the methods below use Adobe, Apple, Google and open-source software. Vendor steps were checked on each vendor's own pages in October 2026. ## How do you unlock a PDF? Open the PDF with its password, then save a copy without the security settings. Which tool you use depends on what you have: Acrobat removes either password from its security settings, Preview on a Mac exports a copy with new permissions, any browser can print a readable file to a fresh PDF, and qpdf decrypts a file on the command line. Every method needs either the open password or a file that already opens without one. ## What is the difference between an open password and a permissions password? A PDF's encryption has two passwords, and they do different jobs. | | Open password (user password) | Permissions password (owner password) | |---|---|---| | What you see | A prompt before the file opens | The file opens, but some actions are greyed out | | What it blocks | Reading anything | Printing, copying text, editing, filling or extracting pages | | Can you unlock it without the password? | No | Often you can make an unrestricted copy, if the file opens | | Typical source | Bank statements, payslips, confidential reports | Published reports, forms, e-books, signed documents | The open password is real protection: the contents are encrypted with a key derived from it, so without it the file is unreadable. The permissions password is closer to a request. The file is still encrypted, but any reader can decrypt it to display it, and it is the reader that chooses to honour the restrictions. The qpdf manual puts it plainly: restrictions "may or may not be enforced by any particular reader", and qpdf "does not obey encryption restrictions already imposed on the file." ## How do you remove a PDF password in Adobe Acrobat? Acrobat removes either password from the document's security settings, as long as you can open the file and you know the permissions password. The open password alone is not enough to change security. The path below is the one Adobe's community experts give; Adobe's own help page would not load for us in October 2026, so check it against your version. Some versions also offer **Remove Security** under the Protect tool. ### Step 1: Open the PDF in Acrobat Enter the open password if it asks for one. You need the full Acrobat app; according to Adobe's community answers, the free Acrobat Reader cannot change a document's security. ### Step 2: Open the security settings Choose **File > Properties** (Ctrl+D on Windows, Command+D on a Mac) and open the **Security** tab. ### Step 3: Set the security method to No Security In **Security Method**, choose **No Security**. Acrobat asks you to confirm, and asks for the permissions password if the file has one. ### Step 4: Save the file Click **OK**, then save. Save under a new name if you want to keep the protected original. One case Acrobat will not change: a PDF secured with a server-based security policy. Only the policy's author or a server administrator can lift that. ## How do you unlock a PDF on a Mac with Preview? Preview can save a copy of a PDF with different security settings, through the same **Permissions** dialog it uses to add them. Apple's Preview guide for macOS 27 (October 2026) documents that dialog for setting passwords; clearing its options is how you take them off. Apple's page does not describe removal as a separate command, so check the result by reopening the copy. 1. Open the PDF in Preview and enter its open password. 2. Choose **File > Export** and give the copy a new name, so the original stays as it is. 3. Click **Permissions**. Deselect **Require Password To Open Document**, and select the actions you want to allow without a password, such as printing. 4. If Preview asks for the owner password, enter it. Then click **Apply** and **Save**. To change the original file in place, **File > Edit Permissions** opens the same options. Users on Apple's community forums report that behaviour has varied between macOS versions, so try it on a copy first. ## How do you unlock a permission-locked PDF in Chrome or another browser? If the PDF opens without a password but blocks copying or editing, printing it to a new PDF gives you a copy with no restrictions attached. This works in Chrome, Edge, Safari or Firefox, and it is the quickest option when you do not have Acrobat. It does not work on a file that also blocks printing, and it cannot get you past an open password you do not know. ### Step 1: Open the PDF in the browser Drag the file onto a browser window, or right-click it and open it with the browser. Enter the open password if there is one. ### Step 2: Open the print dialog Press Ctrl+P on Windows or Linux, or Command+P on a Mac. Google's Chrome help page (October 2026) describes the same route through **File > Print** for any page or file Chrome has open. ### Step 3: Choose Save as PDF as the destination In the print window, set **Destination** to **Save as PDF** instead of a printer. ### Step 4: Save the new file Click **Save** and pick a name. The new PDF is a fresh file, so it carries none of the original's encryption. The trade-off: printing rebuilds the pages, so links, bookmarks, form fields and digital signatures may not survive, and a signed document stops being a verifiable signed document. Use this for reading, quoting and printing, not to replace an original you need to keep intact. ## How do you remove a PDF password with qpdf? qpdf is a free, open-source command-line tool for transforming PDFs, and its `--decrypt` option writes a copy with no encryption at all. The qpdf 12.4.2 manual (October 2026) describes `--decrypt` as creating "an output file with no encryption even if the input file is encrypted", and `--password` as the way to supply "a password for accessing encrypted, password-protected files." ### Step 1: Install qpdf It is in the usual package managers: `brew install qpdf` on a Mac, `apt install qpdf` on Debian or Ubuntu, and builds for Windows are linked from the project's site. ### Step 2: Decrypt a file that opens without a password For a PDF with only a permissions password, run: ```bash qpdf --decrypt locked.pdf unlocked.pdf ``` ### Step 3: Supply the open password if there is one For a PDF that needs a password to open, pass it in: ```bash qpdf --password='your-password' --decrypt locked.pdf unlocked.pdf ``` On a shared machine, `--password-file` reads the password from a file or standard input instead of leaving it in your shell history. qpdf keeps the pages, links and structure intact, which makes it the better choice than printing when the file has forms or bookmarks. A shell loop runs it over a whole folder. The manual adds a caution of its own: decryption "is not intended to be used for bypassing copyright restrictions or other restrictions placed on files by their producers." ## Is it legal to unlock a PDF? It is when the document is yours, or when you have the password and permission to use the file as you intend. A permissions password is the document owner saying how the file may be used. Removing it from someone else's report, e-book or form may breach their terms of use or a licence you accepted, even when a tool lets you do it. In some countries, circumventing protection on copyrighted material is unlawful in itself. When in doubt, ask the sender for an unrestricted copy. And if you have forgotten the open password to your own file, there is no legitimate shortcut. The contents are encrypted with a key that comes from that password. Online "PDF password recovery" services work by guessing it, which only succeeds for short or common passwords, and they require you to upload a confidential file to a stranger. The better routes are the sender (banks and payroll providers can reissue a statement or tell you the password format they use), a backup of an unprotected version, or the original document the PDF was made from. ## What can you do with a PDF once it is unlocked? Whatever the restrictions were blocking: combine it with other files, shrink it to send, sign it or edit it. Our free browser tools work on the unlocked copy without uploading it anywhere: [merge PDF files](https://thedrive.ai/tools/merge-pdf) into one document, or [compress a PDF](https://thedrive.ai/tools/compress-pdf) that is too large to email. For changes beyond pages and size, such as filling a form or editing text, see the guide to using an [AI PDF editor](https://thedrive.ai/blog/ai-pdf-creator-fill-edit-manipulate). ## Frequently Asked Questions ### Can you unlock a PDF without the password? Only when the lock is a permissions password. If the file opens without a prompt but blocks printing, copying or editing, you can print it to a new PDF or run `qpdf --decrypt` to get an unrestricted copy. If it asks for a password before it opens, the contents are encrypted and nothing legitimate opens it without that password. ### Why can I open a PDF but not copy text from it? The file has a permissions password, also called an owner password, that tells PDF readers to block copying. The text is still there; the reader is honouring a restriction. If you have the right to use the text, print the file to a new PDF, or ask the sender for an unrestricted copy. ### Does unlocking a PDF reduce its quality? Removing the password in Acrobat, Preview or qpdf does not change the pages; the file is the same, minus the encryption. Printing to a new PDF from a browser rebuilds the pages, so it can drop links, bookmarks, form fields and signatures, though the text and images look the same. ### Is it safe to use an online PDF unlocker? It means uploading the file to someone else's server, and a password-protected PDF is usually protected because it is confidential: a bank statement, a payslip, a contract. Prefer a method that runs on your own computer, such as Preview, a browser's print dialog or qpdf, which never send the file anywhere. ### Does The Drive AI unlock PDFs? No. The Drive AI's free PDF tools merge, split, compress, rotate, watermark and sign PDFs, and none of them removes a password. Unlock the file with one of the methods above first. The agent can add a password to a PDF, and it can open a protected PDF to work on it if you give it the password. --- Once a PDF is unlocked, most of what people do next is ordinary file work: merge it into a packet, compress it to send, file it with the rest of the documents it belongs to. The [free PDF tools](https://thedrive.ai/tools) handle the single-file jobs in your browser. When the work is a folder of PDFs to sort, rename or summarise, The Drive AI's agent does it from a plain-English request, with a preview of every change before it happens.
