Online File Type & MIME Detector
Accurately identify the real file type and MIME type of any file using binary-level inspection — not just by file extension.
This browser-based tool supports batch detection and folder-level scanning, covering a wide range of file formats including images, videos, documents, archives, fonts, and more.
✅ What This Tool Does:
Detects the true file type and corresponding MIME type from the file's internal binary content.
Accurately reports misnamed files. For example, if a file is named demo.jpg but is actually a PNG image, the tool will detect it as PNG and show image/png as the correct MIME type.
100% privacy-friendly: All file analysis is done locally in your browser, and no data is uploaded to any server.
Supports batch file analysis and folder selection — there is no limit to the number of files you can scan. Performance depends on your device and browser, and the tool can theoretically handle tens of thousands of files.
