What this file tool does
Encrypt one file with AES-256-GCM using a PBKDF2-derived key, a unique random salt, a unique IV, and a self-describing Callfile header.
The result is calculated from the actual bytes and metadata of the files you provide, using browser-native APIs.
Your files stay in this browser tab. Performance and maximum file size depend on the memory available to your browser.
Supported inputs and limits
Use current desktop versions of Chrome, Edge, Firefox, or Safari. Browser memory and security restrictions may limit very large jobs.

Example and practical tips
Try the tool on a small copy of your files first. Check the downloaded result before changing or deleting any original data.
- Keep a backup for important work.
- Avoid closing the tab during processing.
- Use clear output names so results are easy to identify later.
Frequently asked questions
Can I use the aes file encryptor without uploading files?
Yes. Processing happens locally in your browser, and the page does not send the selected file contents to a server.
Will the aes file encryptor change my original files?
No. Browser file access is read-only here. The tool creates a new downloadable result and leaves the originals untouched.
What happens if I close the tab before downloading?
The generated result is held temporarily in this tab. Closing or refreshing the page clears it, so download the result first.
Can I process very large files in a browser?
It depends on available memory, browser limits, and the operation. Start with a smaller batch if the page becomes slow or unresponsive.
Does a successful result guarantee that every file is safe?
No. This tool performs the stated file operation only. It is not an antivirus scanner and does not certify the trustworthiness of file contents.
