What does this tool show?

File name — the original filename including extension
File size — in bytes, KB, and MB
MIME type — the browser-reported media type (e.g., image/jpeg, application/pdf)
Last modified — the last-modified timestamp from the filesystem
Image dimensions — width × height in pixels and aspect ratio (images only)

No files are uploaded to any server. All analysis is performed entirely in your browser using the File API. Your files never leave your device.
