This application is an ultimate PDF password remover tool that enables you to unlock PDF files online using your browser. You can easily unprotect PDF files and remove password security when it is no longer needed without installing any software in seconds.
PDF (Portable Document Format) contains all the required information about the printed documents, furthermore, you can scroll through the document, search text, fill input fields, add comments, and protect a file from being opened by unauthorized users. Protection is required when we want to secure sensitive or personal information and to make sure that the only person with the password can open and view your file. Of Course, PDF security can't fully protect your file from brute-force password attacks so it is good to remember to set complex passwords created by password generators.
PDF format supports multiple levels of protection. When protecting the PDF you can set Document Open Password (User Password) that will be required to open a file. You can also set Permissions Password - the password for changing document permissions such as permission for printing, text copying, and editing.
When a PDF document is protected with Document Open Password you will be prompted to enter a password to open a file and view its contents.
To unlock PDF files using GroupDocs.Unlock application, upload your file, type the password, click Unlock button, then download the unprotected file. The download link will be available for 24 hours then we automatically remove the files from our servers.
