File Metadata Viewer — Name, Size & Type Info
Inspect a file’s basic properties, browser-reported MIME type, detected signature, hash, and first-byte sample before sharing, documenting, or comparing it.
Works with
Any file type
Hashing
SHA-256
Signature
Magic bytes
Workspace
Inspect a file locally in your browser.
Drop a file here or click to browse
Works with any file up to 150 MB. The tool reads metadata, computes a SHA-256 fingerprint, and inspects the first bytes locally.
What you get
- File name, extension, size, and timestamps
- Browser MIME type
- Detected format from magic bytes
- SHA-256 file fingerprint
- Hex and ASCII preview of the first bytes
Why it helps
This is useful for quick triage, documentation, basic forensic checks, comparing files, spotting renamed formats, and preparing clean notes before you open a suspicious file elsewhere.
Summary
