How to protect PDF files — instructions
- Drag the PDF file into the upload area or click to choose files.
- Enter the password you want to use in the “Password” field.
- If needed, enter an “Owner password”. If you leave this field empty, the same password will be used.
- Set the printing, copying, and editing permissions. To restrict an action, uncheck the corresponding option.
- Click “Protect PDF” — the protected file will be downloaded to your device automatically.
Protect PDF files with a password and access restrictions
PDF documents often need to be shared without giving every recipient unrestricted access to their contents. Konvertus lets you protect PDF files with a password and separately control whether printing, copying, and editing are allowed.
The protection can be configured according to how the document should be used. If someone only needs to read the PDF, copying, editing, and printing can all be restricted. If printing should remain available, that permission can stay enabled while the other actions are blocked.
The file is processed directly on your device without being uploaded to the Konvertus server. After protection is applied, the resulting PDF is downloaded automatically.
What PDF protection options are available?
In addition to setting a password, Konvertus provides three separate permissions:
- allow printing;
- allow copying;
- allow editing.
When an option is checked, that action remains available. To restrict it, uncheck the corresponding option before processing the document.
This means you do not have to block every action at once. For example, you can allow printing while restricting copying and editing. You can also prevent editing while keeping printing and copying available.
Before clicking “Protect PDF”, check all three options to make sure the resulting document has the permissions you need.
Password protect PDF files
The “Password” field is used to set a password for opening the document. Once protection has been applied, the password will be required to access the contents of the file.
To password protect PDF files, add the document, enter the password you want to use, and configure the printing, copying, and editing permissions. Then click “Protect PDF”. The protected file will be downloaded to your device automatically.
Keep the password in a safe place. If you send the protected document to another person, they will also need to know the password to open it.
The opening password and PDF permissions serve different purposes. The password controls access to the document, while the permissions determine which actions are available after the PDF has been opened.
What is an owner password?
Konvertus also provides a separate “Owner password” field. This password is associated with the permissions applied to the protected PDF.
Entering a different owner password is optional. If you leave the field empty, the same password entered in the main “Password” field will be used. This is also stated directly below the owner password field.
Using separate passwords can be useful when access to the document and control over its restrictions need to be separated. If you do not need that separation, simply leave the owner password field empty.
Before protecting the document, check both the password settings and the selected permissions.
Protect PDF from editing
Sometimes a document needs to remain readable but should not be modified. Editing can be restricted independently of printing and copying.
To protect PDF from editing, uncheck “Allow editing” before processing the file. “Allow printing” and “Allow copying” can remain enabled if those actions should still be available.
This makes it possible to create a PDF that can be opened, read, printed, and copied while restricting normal editing. If copying should also be limited, uncheck that permission as well.
Because each permission is controlled separately, you can choose the combination that matches the intended use of the document.
Protect PDF from copying
If recipients need to read a document but should not be able to use the normal copy function, disable the “Allow copying” option.
To protect PDF from copying, uncheck this option before applying the protection. Printing and editing can be configured separately, so you can still allow the document to be printed while restricting copying.
After processing, the selected copying restriction is stored in the PDF. PDF readers that respect document permissions should not provide the normal copying function for protected content.
Copy restrictions should not be treated as absolute protection against every external method of capturing visible information. For example, restricting copying does not prevent someone from taking a screenshot. The setting controls the copying permission provided by the PDF format.
How to restrict copying and editing at the same time
If a document should remain readable while both copying and editing are restricted, disable both corresponding permissions.
For users looking for how to protect PDF from copying and editing, uncheck “Allow copying” and “Allow editing”. Printing is controlled independently and can either remain available or be restricted as well.
You can also set an opening password at the same time. This lets you control both who can access the document and which actions are available after it is opened.
Remember that a checked permission means that the action remains allowed. Review all three checkboxes before clicking “Protect PDF”.
Can printing be restricted?
Yes. Printing is controlled separately from copying and editing. If the document should only be viewed on screen, uncheck “Allow printing”.
If recipients need to print the PDF, leave this option checked. You can still disable copying or editing without affecting the printing permission.
For example, a document can be readable and printable while normal copying and editing are restricted. Alternatively, only editing can be disabled while both printing and copying remain available.
These separate permissions make it possible to configure the PDF according to how the recipient needs to use it.
Encrypt PDF with a password
In English search results, encrypt PDF is also commonly used for protecting PDF documents with a password. Konvertus lets you define the password before processing the document and configure the available permissions at the same time.
The password controls access to the PDF, while the individual settings determine whether printing, copying, and editing remain allowed.
After the protection settings are configured, click “Protect PDF”. The resulting file is downloaded automatically, so there is no separate download page or additional button required.
Before sharing the protected document, you can open the downloaded file and verify that the password and selected restrictions work as intended.
Protect PDF online without uploading it to a server
To protect PDF online, drag the document into the upload area or click to choose a file from your device. Enter a password, add an owner password if needed, and configure the three permissions.
Processing takes place without uploading the PDF to the Konvertus server. Once everything is configured, click “Protect PDF”. The protected document is then downloaded automatically to your device.
The resulting file remains a PDF that can be stored, shared, and opened using software that supports the format. What changes are the access settings and the permissions applied during protection.
If an opening password has been set, it will be required to access the file. If printing, copying, or editing has been disabled, PDF readers that support these permissions should apply the selected restrictions.
What to consider before protecting a PDF
A password and document permissions do not perform the same function. A password limits access to the file, while permissions determine what a user can do after opening it.
Before processing the PDF, decide which actions the recipient actually needs. If the document is only meant to be read, printing, copying, and editing can all be restricted. If it must also be printed, keep the printing permission enabled.
It is also important to save the password before sharing the file. The protection page does not provide a function for recovering a forgotten password.
PDF permissions also do not replace control over who receives the document itself. The selected restrictions affect how compatible PDF software handles the file, while sharing the document remains a separate action.
Frequently asked questions
How do I protect a PDF with a password?
Add the PDF, enter the password you want to use, configure the printing, copying, and editing permissions, and click “Protect PDF”. The protected file will download automatically.
Can I use a different owner password?
Yes. Konvertus provides a separate “Owner password” field. If you leave it empty, the same password entered in the main password field will be used.
How do I prevent a PDF from being edited?
Uncheck “Allow editing” before protecting the document. Printing and copying can remain enabled if you still want to allow those actions.
How do I prevent copying from a PDF?
Uncheck “Allow copying”. After processing, the PDF will contain the corresponding copying restriction.
Can I restrict copying and editing at the same time?
Yes. Uncheck both “Allow copying” and “Allow editing”. Printing can be allowed or restricted separately.
Can I prevent a protected PDF from being printed?
Yes. Uncheck “Allow printing” before clicking “Protect PDF”.
How do I open a password-protected PDF?
If an opening password has been set, enter that password when opening the document in your PDF reader.
Is the protected PDF downloaded automatically?
Yes. After processing, the protected PDF is automatically downloaded to your device.
Is my PDF uploaded to a server?
No. The file is processed without being uploaded to the Konvertus server.
Does copy protection prevent every way of copying content?
No. The restriction limits the normal copying function in PDF software that respects document permissions. It does not prevent external methods such as taking a screenshot.
