Fast workflow
Designed to reduce friction with direct upload, quick processing, and one-click export.
Open Steganography, add your file, then choose the target output and run conversion.
This tool is optimized for security utilities and works best with * as inputs.
When processing completes, download the result in * and verify quality before sharing.
Steganography is a privacy-first utility for fast security utilities. It helps you move from * to * with consistent output quality.
Designed to reduce friction with direct upload, quick processing, and one-click export.
Files are handled in an isolated processing flow with minimal retention and clear user controls.
Outputs are tuned for real use cases across *.
A predictable sequence keeps conversion stable across devices and file sizes.
Steganography accepts * and exports *.
The pipeline is designed for privacy-first processing with clear user control over inputs and outputs.
Use high-quality source files, choose the closest matching target format, and avoid repeated reconversion cycles.
Steganography follows a deterministic conversion flow so results are repeatable and easier to troubleshoot when a file behaves unexpectedly.
Hide a file inside an image or extract hidden files. 100% local.
All steganography runs entirely in your browser using LSB (Least Significant Bit) pixel manipulation via the Canvas API. No files are uploaded to any server. The cover image and payload never leave your device.
Uses LSB (Least Significant Bit) steganography to embed file data inside the RGB pixel channels of a cover image. Each pixel stores 3 bits of payload data (one per color channel), making the visual change imperceptible. The output is always PNG format to preserve exact pixel data — JPEG recompression would destroy hidden data. The embedded file includes a magic header (CCSTEG1), original filename, MIME type, and payload length for reliable extraction.
For basic data concealment demos, bundling small config files into images, watermarking with hidden identifiers, or educational purposes. Not a substitute for encryption — combine with File Encryptor for real secrecy.
