Embed. Extract. Detect.
Stegodon is a browser-based steganography tool by QVLx for hiding messages or files inside images and WAV audio.
It provides three primary workflows:
- Embed — hide text or a file inside an image or WAV carrier
- Extract — recover a hidden payload from a stego image or WAV
- Detect — analyze a file for signs of LSB-based steganography
All processing runs locally in the browser.
Core Features
| Feature | Description |
|---|---|
| Image steganography | Hides payload bits in image RGB least significant bits |
| WAV steganography | Hides payload bits in PCM WAV sample least significant bits |
| Text payloads | Embed plain text messages |
| File payloads | Embed arbitrary files and preserve the filename |
| 1-bit or 2-bit LSB | Choose stealthier or higher-capacity embedding |
| Channel selection | Choose R, G, B, or combined channels for images |
| Randomized placement | Shuffle payload placement using a passphrase-derived seed |
| Encryption | Encrypt payload bytes using AES-GCM |
| Capacity analysis | Estimate approximate carrier capacity before embedding |
| Extraction | Recover text or downloadable file payloads |
| Detection | Search for a Stegodon header and compute LSB suspicion heuristics |
| On-device processing | No server upload or cloud processing required |
| Theme support | Multiple built-in interface themes |
Supported Carrier Types
Images
Stegodon accepts image files as carriers and exports the stego result as PNG.
PNG is used because lossless output preserves exact embedded bits.
Audio
Stegodon supports WAV (PCM 8-bit or 16-bit) files.
Compressed audio formats are not supported for embedding or extraction.
Typical Use Cases
- Hide a private note inside an image
- Conceal a small file inside a carrier image or WAV
- Demonstrate LSB steganography for educational purposes
- Recover previously embedded payloads
- Run a quick heuristic detection pass on suspicious media
Important Notes
- Stegodon is designed around LSB steganography
- Detection results are heuristic, not definitive proof
- JPEG or heavily edited media may destroy hidden data or produce noisy detection results
- Using 2-bit embedding increases capacity but makes changes easier to detect
- Randomization and encryption are independent features and can be used together
Main Sections
Stegodon is organized into four tabs:
- Embed
- Extract

Privacy
Stegodon performs embedding, extraction, and detection locally in your browser.
No backend upload workflow is implemented in the supplied application code.
