The Image Format Detector identifies the format, dimensions, and properties of any uploaded image. It reads the actual file data, not just the extension.

This is useful for images with incorrect or missing extensions, or when you need to quickly check image properties.

Upload any image to see its format, MIME type, file size, and a preview.

Everything runs in your browser. Your images are never uploaded to any server.
