What is a document protection, and why do I need it?

Document protection is the process of adding a password to a document to restrict unauthorized access and modification. It is necessary to protect sensitive or confidential documents from unauthorized access, copying, and distribution. Password-protected documents ensure that only authorized users can access and modify the contents of the document. It is especially important for businesses, government organizations, and individuals who deal with confidential information to safeguard their documents from unauthorized access or modifications.

What file formats can be protected using document protection app?

The app supports the protection of various file formats, including PDF, DOC, DOCX, ODT, PPT, PPTX, ODP, XLS, XLSX, ODS, and ONE.

What is the maximum file size that can be protected?

The maximum file size that can be protected using this app is 10 MB. Any file larger than that cannot be processed for protection.

Is it necessary to install any software to use this app, or is it entirely web-based?

You do not need to install any software to use this app, as it is entirely web-based. You can access it from any device with a web browser, regardless of the operating system. This makes it convenient to use and eliminates the need to download or install any additional software.

Will the app store my documents after they are protected, and if so, how long will they be stored?

No, the app does not permanently store your protected files after the operation is completed. All files are automatically deleted from the server after 24 hours to ensure the security and privacy of your documents.

Can I remove password protection from a file once I have added it?

Sure, it is possible to remove the password protection from a file that has been password protected using our unlocker app or the native application for the document. However, you would need to provide the previous password to remove the protection.
