Import and export
Import content using a tool's file picker. Follow its instructions to preview, save or share the result. Exporting does not automatically replace your original files. Review results and keep backups of important originals.
Permissions and compatibility
Camera, microphone and photo-library permissions are used only by the corresponding features and can be changed in Settings. Supported formats, size limits and feature boundaries are described within each tool. Some features require real device hardware.
Using calculation results
Health, fitness, financial and scientific calculators provide general information and estimates. Read the assumptions and limitations shown by each tool. Results do not replace professional advice and must not guide driving, medical emergencies or other safety-critical decisions.
