Localix
Local privacy.

macOS Native Apple Silicon

Localix is a native macOS privacy toolkit designed for anyone who handles sensitive images — journalists, security researchers, OSINT analysts, and privacy-conscious users. Strip metadata, split secrets, hide files in plain sight, watermark, encrypt, and batch-process everything locally. Nothing ever leaves your machine.

Everything you need

Six tools. One application.
Zero compromises.

Every operation runs locally. Your files never touch the network.

Metadata Stripping

Remove EXIF, XMP, IPTC — every byte of embedded metadata — using exiftool -all=. Operates on a clean copy so your originals are never modified.

Batch support • Zero-loss

XOR Secret Sharing

Split any image into 3 cryptographically-random shares. No single share reveals anything. All 3 shares required for reconstruction. Pure random noise, impossible to brute-force.

3-of-3 scheme • os.urandom()

LSB Steganography

Hide any file inside a carrier image by replacing the least significant bits of each pixel. Optional XOR-based password protection with SHA-256 key derivation.

Encode / Decode • Password protection

Watermarking

Two modes: simple single-position text overlay with configurable opacity, or Filigrane — a repeating tile pattern with density and orientation controls. Save and load presets per project.

Presets • Filigrane mode

Secure Containers

Encrypt all processed output into a single password-protected archive. AES-256 via pyzipper with PKWARE ZipCrypto fallback. Optional auto-wipe of originals after packing.

AES-256 • Auto-wipe

Batch Processing

All operations support multiple files simultaneously. Live progress bar with per-file error reporting. Output organized by date and image name in a clean directory structure.

Multi-file • Progress bar

Simple workflow

Select. Configure. Execute.
No learning curve.

Select Files

Drag and drop or pick files. All common image formats supported — JPEG, PNG, HEIC, WebP, TIFF.

Choose Operation

Pick from the tab bar: Metadata, Crypto, Steganography, Watermark, or Container. Configure your options.

Execute

Hit the action button. Everything runs locally. Output is saved to a neatly organized directory.

Privacy Guarantees

Trust is not required.
Verification is.

Localix makes zero network connections. No telemetry, no analytics, no crash reporting. Every operation is fully offline.
