Private by design
This tool processes the files and text you select inside your browser. It does not upload their contents to Azad. Your original files remain unchanged unless you explicitly download a new result.
Browser compatibility
Modern Chrome, Edge, Firefox, and Safari are recommended. Very large files may be limited by the memory available to your browser and device.
