File Type Detector
Detect file types by reading magic bytes.
What This Tool Helps You Do
File Type Detector helps you detect file types by reading magic bytes. It is designed for people repackaging files, comparing versions, checking formats, and moving content between common file types who need file type, magic bytes, and detect format without switching into a heavier toolchain than the task actually requires.
Use these utilities when you need quick file inspection, conversion, packaging, extraction, or checksum verification from one place. On this page, the focus is file type and magic bytes. For this tool, the main processing happens in your browser tab and the output is prepared on the same device. That makes it a better fit for quick edits, conversions, cleanup, and review work that should stay close to the source file or pasted data.
