Step 1

Open the File Encryptor at ConvertCraft by navigating to <https://www. convert-craft. com/tool/file-encryptor/> in any modern web browser.

Step 2

Select the files you wish to secure directly from your local storage. Because this is a 100% local (WASM) tool, the files are processed instantly within your browser environment without any server-side interaction.

Download your encrypted files directly to your machine. Once the process is complete, the files are ready for secure storage or transmission, having never touched a third-party server.

Tips for Best Results

• Use Modern Browsers: For the best performance with our WebAssembly-based processing, ensure you are using an up-to-date version of Chrome, Firefox, or Edge. These browsers are optimized for local file processing, ensuring a smooth experience.
• Manage Batch Sizes: Remember that the free tier allows for up to 5 files per batch. If you have a large folder of documents, process them in smaller groups to maintain optimal browser performance.
• Verify File Integrity: Since all operations are 100% local, you can verify your encrypted files immediately after the process finishes. This local file processing approach eliminates the risk of data corruption during transit to a server.
