Universal File Inspector

Upload a file and DevNestro will show what it contains, potential privacy concerns, and which tools can work with it.

Drop a file or choose one. Type is detected from signatures when possible.

      FAQ

      Do you trust the file extension?

      No. The inspector checks magic bytes for common types such as PDF, JPEG, PNG, WebP, and ZIP-based Office files, then falls back to MIME and name.

      Is the file uploaded?

      No. Bytes stay in the browser. Starting a Smart Workflow stores an artifact in IndexedDB on this device only.

      Read the original guide: Inspect a file once, then pick the right DevNestro tool or workflow.
