This PDF lock tool allows you to set a password on a PDF file so that it cannot be opened without the correct credentials. Password protection is useful when you share sensitive documents such as contracts, financial statements, personal records, or internal reports. By applying encryption at the document level you add an extra layer of security on top of email or storage protections. After uploading your PDF you choose a strong password, then download the protected version and distribute it only to people who should have access. This approach helps reduce the risk of accidental exposure, especially when files are forwarded or stored in shared locations.
