About Password Protect app
Different file formats like PDF, ZIP, etc. allow the protection of a file from being opened by unauthorized users. The only person who knows the password can view or modify your file. This protection cannot fully secure the file from brute-force password attacks, so remember to set complex passwords created by password generators
This free online application based on the GroupDocs API adds password protection to different files. You specify the desired password to protect the file. We value your privacy, so the file and the password are visible to you only. You can download the protected file to share it securely. The application works on any device, including smartphones.
