The Problem:
As a developer and data security engineer, I regularly handle files from unknown or untrusted sources. My old workflow was messy and fragmented: separate tools for checksums, hex viewing, EXIF lookup, and document metadata review.
It gets risky and time-consuming when you need to verify if a file extension is fake, inspect nested content inside Office/iWork/PDF files, uncover incomplete redactions, or audit private embedded data before sharing files.
Comparison:
Most existing tools either lack deep inspection or objects extractions capabilities or lock advanced features behind expensive bulky suite subscriptions, or just simply not maintained any more.
- File Info Professional: outdated, and checksum/hex only
- More Info: only checksums
- FileMate: EXIF and metadata
The Solution:
File Deep Info works as an all-in-one native macOS forensic & privacy inspection utility, consolidating all file deep analysis into a single lightweight app — no more juggling multiple CLI or standalone tools.
Core Capabilities:
- Hidden Data Discovery Uncover hidden rows/sheets, invisible white-on-white text in Office files, fake PDF redactions, hidden layers, and trailing/steganography data inside images.
- True Format Identification Ignore misleading file extensions to detect spoofed formats, disguised executables, and extension-less suspicious files.
- Metadata & Privacy Audit Extract full edit history, author info, EXIF/GPS data, and macOS extended attributes — including the original download source URL of a file.
- Embedded Object Extraction Drill into internal document structure and extract nested assets: media inside PDFs, OLE objects in Office/iWork docs, and nested embedded content.
- Hex & Checksum Tools Instant MD5/SHA hash calculation plus hex header preview for fast file signature validation.
Why use this?
Perfect for anyone inspecting sketchy files before opening, verifying whether PDF redactions actually remove sensitive content, or auditing personal/client documents for private metadata leakage — all in one, no subscription, no telemetry, no tracking, 100% offline!
Pricing:
- Free Tier: Full fingerprint analysis, format detection, metadata extraction, and hidden content discovery — covers nearly all the daily use cases.
- Pro Version: $12.99 for one-time purchase to unlock Shadow Data deep parsing, recursive multi-level analysis (Analyze in New Window), and unlimited embedded object extraction.
