Save refers to storing your file in the application's default format, preserving all editable data, settings, and layers. Export converts your current file or project into a different file format suitable for use outside the original application, often simplifying the content for broader compatibility. The core distinction lies in intent: Save keeps your work within the native environment for future editing, while Export prepares a version optimized for sharing, printing, or use in other software.

For example, in photo editing software like Photoshop, using "Save" stores the layered PSD file for future edits. Using "Export As" creates a flattened JPEG for sharing online. Similarly, in a document editor, "Save" keeps the editable DOCX file, while "Export" generates a PDF that maintains formatting but restricts editing.

The key advantage of Save is maintaining full editability. Export's strength is creating universally accessible or specialized output formats. However, Export often reduces file complexity, potentially losing layers or editing history. Choosing correctly is crucial: Save for ongoing work, Export for final sharing. Improper reliance solely on Export can result in lost original work.
