About Password Protect Files
Add password protection to PDFs, photos, Word documents, spreadsheets, videos, archives, code, or any other file by placing them inside a standard AES-256 encrypted ZIP. The password and unencrypted contents remain in this tab. Everything happens locally in your browser: nothing is uploaded, stored, or logged. This focused Password Protect Files page is designed for people securely sharing or storing any kind of file behind one password without handing the unencrypted contents to a remote service. It opens directly to the working tool, rather than hiding the function inside a general converter or account dashboard.
The input is parsed by JavaScript already loaded in the page, transformed in memory, and returned through a local browser download or copy action. Your filename and file contents stay on the device. There is no upload queue, temporary cloud copy, account record, or server-side conversion job to delete later. That makes the tool practical for personal records, work material, and drafts that should not be handed to an unknown processing service.
The important limitation is straightforward: Because arbitrary file formats do not share one password standard, the result is an encrypted ZIP rather than a modified original file. The recipient needs an archive app with WinZip AES support, such as 7-Zip, WinRAR, Keka, or a current system archive utility. Knowing that boundary helps you choose the right source file and check the result before relying on it. Processing speed and maximum size depend on your browser and available device memory, which is the honest trade-off for doing the work locally.
FileForge charges nothing for this tool and does not add a watermark. Once the page and its processing engine have loaded, the operation can continue without sending the file over the network. Use the numbered steps below, download the result, and review it before replacing an original file.
