File Sniff

File Sniff tells you what a file really is. It reads file headers and container structure instead of trusting the extension, and flags mismatches such as a video named .pdf or a program named .jpg. Unknown content is reported as Unknown.

File analysis runs on your device. File Sniff does not upload the files you scan, their names or their contents. There is no account to create.

SCAN AND COMPARE
• Import files and folders from Files, or use the Share extension from apps such as Mail.
• Identify images, audio, video, archives, documents, fonts, executables and text.
• Search, sort and filter mismatches. See diagnostic notes for incomplete or unusual files.
• Use the side-by-side inspector on iPad and keyboard commands on supported devices.

SAVE COPIES WITH PRO
• Save a copy with the detected extension. Original files stay unchanged.
• Run supported conversion and extraction actions on selected files and choose where to save the results.

INSPECT WITH FILE SNIFF PRO
• Read image metadata, document properties, archive contents, hex bytes and SHA-256 hashes.
• Inspect embedded Content Credentials (C2PA) and IPTC provenance declarations. File Sniff reads declarations; it does not verify C2PA signatures or decide whether a file is safe or AI-generated.
• Convert Outlook .msg messages to .eml, convert images, remove image metadata, and extract attachments from winmail.dat.
• Export results as CSV or JSON.

File Sniff Pro is available as a lifetime purchase or an auto-renewing annual subscription. Eligible customers can try the annual plan free for seven days. Prices and eligibility are shown in the app before purchase. Pro works across Mac, iPhone and iPad with the same Apple Account; available actions vary by platform. Manage or cancel subscriptions in your App Store account settings.
