Pick a file and see everything the browser can read: name, size, type, dates. For images you get dimensions and aspect ratio; for audio and video you get duration and format. All processing stays on your device.
Choose a file above and click Extract metadata to see results here.
Basic properties-name, size, MIME type, last modified-are available for any file. Images add width, height, aspect ratio, and total pixel count. Audio and video add duration and format. Documents get a category label. The tool does not read EXIF from images or full document internals; it uses what the browser exposes.
Everything runs in your browser. Files never leave your device. Large media may take a moment to load for duration or dimensions. Some formats may show only basic info.
For checksums and integrity, use the Checksum Validator. For listing folders and basic file info at scale, try the File List Generator. To find duplicate files, use the File Duplicate Finder.
