What is Image Steganography?
Image Steganography is the art and science of hiding secret data inside a cover image. Unlike encryption which makes data unreadable but draws attention, steganography hides the very existence of the secret message, making the cover image look completely normal to the naked eye.
How to use the Image Steganography tool?
- Upload Image: Select or drag and drop your image file (PNG, JPG, WebP) into the upload area.
- Configure Settings: Use the sliders, buttons, or select menus to rotate, adjust, or compress your image as desired.
- Live Preview: View the real-time visual changes instantly in the high-fidelity preview panel.
- Export: Click the export button to download the processed image at full resolution locally to your device.
