As a user of the online tool "I Love PDF", I encounter difficulties when it comes to password protecting a PDF document. Despite the versatile functions of the tool, which include merging, splitting, compressing and converting PDF files, I seem unable to find an effective method for assigning a password to my PDF files. This problem occurs even though the tool offers a user-friendly interface and requires little technical knowledge for most of its functions. This issue affects the security of my PDF documents and has an impact on my work, both in the private and professional context. Furthermore, it raises questions about the security of the data stored on the I Love PDF servers, which is supposed to be deleted after a certain period of time.

To protect a PDF document with I love PDF, you can use the "Password protection" feature. After uploading your document, select this option from the menu. Enter your desired password in the corresponding field and confirm it before clicking on "Protect PDF". Your PDF document will then be secured with the specified password and downloaded. The next time the document is opened, this password must be entered to view it. In this way, I Love PDF offers a user-friendly and effective way to ensure the data security of your PDF documents.
