Hide files inside an image

Steganography conceals data inside another media file. This tool creates a duck image that can carry a hidden payload for private experiments, puzzles, and secure handoffs.

Decode with the right file and password

When decoding, upload the generated duck image and provide the password if one was used. Avoid re-saving or editing the image, because that can damage hidden data.

Common Use Cases

  • Create steganography demos for education.
  • Hide small text or files inside a PNG image.
  • Build puzzle or challenge assets.
  • Experiment with LSB encoding locally.

Frequently Asked Questions

What is steganography?

Steganography hides information inside another file so the carrier still looks like a normal image.

Can I edit the generated duck image?

Avoid editing, resizing, or re-saving it. Image processing can remove or corrupt hidden data.

Is processing local?

Most processing runs locally in your browser whenever possible, so your files are not uploaded for routine conversions and edits.
