Inspect files: sizes, real types from file signatures, hashes and text contents.
Check a file before you trust or share it: generate its hash, detect its real type from its signature, view its first bytes in hex, or analyse a text file's contents. These file tools examine everything in your browser — files are not uploaded anywhere, which matters when the file is sensitive.
The File Hash Generator produces a checksum you can compare against a published one, the MIME Type Detector identifies files whose extensions lie, the Hex File Viewer shows the raw opening bytes, and the Text File Analyzer reports what a plain-text file contains. Developers, support staff and the cautiously minded use them before opening anything unknown. PDF-specific inspection belongs to the pdf tools, typed measurement conversions to the unit converter section, and hashes of pasted text rather than files to the password tools.
