If you know the password of a PDF, Docshar Unlock saves a copy that opens without it. Add the file, type the password in the Password box and click Unlock PDF. If the PDF opens without a password but blocks printing, copying or editing, leave the box empty: Unlock removes those restrictions too.
Bank and card statements, salary slips, insurance documents and downloaded e-documents often arrive protected with a password such as part of your name and date of birth. That is useful while the file travels by email, but tiresome when you open it every day, and many upload forms and other PDF tools refuse protected files.
Only unlock PDFs you own or are authorised to change. Unlock is not a password cracker. It does not guess or recover passwords: you need the password the file asks for. Removing protection from a document you have no right to access may break the law or an agreement with the sender.
Unlocking happens in your browser. The file and the password you type are not sent to Docshar's servers (see the privacy policy). Without an account, files can be up to 10 MB.
Remove the password
- Open the Unlock tool. Go to Docshar Unlock.
- Add the protected PDF. Click Choose file or drop the PDF on the page.
- Enter the password, if the file asks for one. Type it in the Password box. If the PDF opens without a password and only blocks printing, copying or editing, leave the box empty.
- Unlock the PDF. Click Unlock PDF. When it works, Docshar says "Protection removed. Text and quality are unchanged."
- Download and check the copy. Click Download. The file name ends in _unlocked.pdf. Open it to confirm it no longer asks for a password, and that all pages are there.
Two kinds of PDF protection
A PDF can be protected in two different ways, and many people only notice one of them.
| Open password (user password) | Permissions (owner password) | |
|---|---|---|
| What you notice | The PDF asks for a password before it shows anything. | The PDF opens normally, but printing, copying text, editing or filling in may be blocked. |
| What Unlock needs | The open password, typed in the Password box. | Nothing: leave the box empty. Typing the owner password also works. |
| Result | A copy that opens without a password. | A copy without the restrictions. |
A file can have both. In that case, the open password is enough: Unlock removes the restrictions along with it. When you protect a file yourself with Protect, you set the open password and choose the permissions, and you can optionally set a separate owner password.
Permission restrictions are there because the person who made the document chose them. Removing them is technically simple, but only do it when you have the right to use the document that way, for example your own statement that you need to print.
What Docshar Unlock does
- It checks whether the PDF is protected at all. If it is not, you see "This PDF is not protected. Nothing needed to be removed."
- It checks the password you typed against the file. Either the open password or the owner password is accepted.
- It decrypts the file in your browser and saves it without encryption, so the copy opens without a password and with no permission restrictions.
- Before offering the download, it opens the unlocked copy and compares its page count with the original, to make sure the copy is complete.
- It handles the standard PDF password protection used by most software, including RC4, AES-128 and AES-256 encryption.
For a few files, the unlocked copy cannot be rebuilt directly. Docshar then rebuilds the pages as images and tells you so: "Protection removed. This file uses an encryption type that could not be removed directly, so its pages were rebuilt as images (text is not selectable)." The pages look the same, but text can no longer be selected or searched; OCR can make it searchable again.
Messages you may see
- "That password is not correct." Check capital letters, spaces and the order of the parts (for example name then date of birth), and whether the date uses DDMM or DDMMYYYY. The sender's email or website usually explains the format.
- "This PDF needs a password to open. Enter it in the password box and try again." The file has an open password and the box was empty.
- "This PDF uses a custom security handler (for example a certificate). It cannot be unlocked here." See the next section.
- "This PDF is not protected. Nothing needed to be removed." If another app still refuses the file, the problem is something else, for example a damaged file.
Files that cannot be unlocked in the browser
Password protection is only one of the ways a PDF can be secured. Unlock works with the standard password-based protection. It cannot unlock:
- Certificate-protected PDFs, which open only for people who have a particular digital certificate installed, not with a password.
- Files under a rights-management (DRM) system, such as some corporate document-control systems and some e-book or publishing systems. These use their own security handler and usually check with a server who may open the file.
- PDFs whose password you do not know. Docshar has no way around a password and will not try.
For any of these, ask the sender or the document's owner for an unprotected copy, or open it in the software the sender specified.
Finding the password of a statement or e-document
Banks, card issuers, mobile operators and other services usually explain the password format in the email that came with the PDF, or on their website: often some letters of your name combined with your date of birth or part of an account or customer number. For example, UIDAI explains that the e-Aadhaar password is the first 4 letters of the name in capitals followed by the year of birth (UIDAI FAQ). Docshar cannot tell you a password.
After unlocking: signatures and safekeeping
- Digital signatures. Some PDFs, such as signed statements, certificates and e-documents, carry a digital signature that shows they have not been changed. Unlocking rewrites the file, so in the unlocked copy the signature is likely to show as invalid. If a portal or office needs the signed original, give them the file as you received it, together with the password if they ask for it.
- Anyone can open the copy. Store unlocked statements in a safe place and delete copies from shared computers and the Downloads folder when you are done.
- Protect it again if needed. To send it on securely with a password of your choice, use Protect. See how to password-protect a PDF.
- Now other tools work. Docshar's other tools refuse protected PDFs, so unlock first if you want to compress, merge or edit the file.
Tips
- Paste the password from the sender's email if it is written there, to avoid typing mistakes.
- The password field is a normal password box; your browser may offer to save it. Decline on shared computers.
- If you need to submit an unlocked statement under a size limit, see how to compress a PDF to 200 KB, 100 KB or 50 KB.
Frequently asked questions
Can Docshar unlock a PDF if I forgot the password?
No. Docshar Unlock does not crack, guess or recover passwords. If the PDF asks for a password when you open it, you must enter that password. Otherwise, ask the sender for an unprotected copy or for the password format.
My PDF opens fine but I cannot print or copy from it. What do I do?
That PDF has permission restrictions only. In Docshar Unlock, leave the Password box empty and click Unlock PDF to save a copy without the restrictions, as long as you have the right to use the document that way.
Does unlocking change the quality or text?
Normally not: Docshar decrypts the file and keeps its contents as they are, and says "Text and quality are unchanged." For a few encryption types it rebuilds the pages as images instead and tells you so; the text is then not selectable until you run OCR.
Why does Docshar say my PDF uses a custom security handler?
The file is protected with a certificate or a rights-management system rather than the standard password protection. These files cannot be unlocked in Docshar; ask the sender for an unprotected copy.
Is my password sent anywhere?
No. The PDF and the password you type into Unlock are used only inside your browser and are not sent to Docshar's servers.
Ready to unlock your PDF?
Add the PDF, type the password you know (or leave it empty for print and copy restrictions) and download a copy that opens without it.
