Hide text in images
Use pixel-level LSB hiding or trailer-based embedding. Export PNG files that preserve your hidden payload without visible artifacts.
Steganography Studio
Hide and extract text in images, audio, and video
Stego Studio gives you a browser-based steganography app with dedicated pages for each carrier type. Start with the medium you actually need instead of sorting through a generic tool first.

Capabilities
Hide and extract text across multiple media types
Each medium gets its own page, its own guidance, and its own embedded tool experience.
Work with audio files
Embed text in WAV files using PCM sample LSB encoding, or use trailer mode for compressed audio formats like MP3 and AAC.
Embed in video files
Hide text in video containers using trailer embedding. The file stays playable while carrying your hidden message.
Choose your medium
Go straight to the page that matches your file
Dedicated pages for each carrier type with embedded tools and detailed guidance.
Hide or extract text in image files
Use pixel-level image hiding or a trailer-based option depending on how durable the file needs to be after export.
Open image pageWork with WAV steganography or compatibility-first audio files
Use PCM LSB for true waveform-level hiding in WAV, or switch to trailer mode for compressed audio workflows.
Open audio pageHide text in video with a browser-safe workflow
Use video trailer embedding when you need the file to stay playable without betting on fragile browser-side frame encoding.
Open video pageHow it works
Three simple steps
A simple workflow that gets you from carrier selection to exported result.
Choose a carrier
Start with image, audio, or video depending on the file you actually need to work with.
Hide or extract text
Use the embedded medium page or the full app to encode a message or recover one from an existing file.
Export and keep moving
Download the resulting file or copy the extracted text without leaving the browser workflow.
Why use it
Start from the workflow you have
Built around real use cases instead of forcing every tool into one generic interface.
One tool for three media types
You do not need separate utilities just to move between image, audio, and video text hiding workflows.
Hide and extract from the same interface
The app is built for round trips, not just encoding. Pick a medium, hide text, and recover it later from the same surface.
Useful for learning and practical tests
The medium-specific pages explain the tradeoffs, limitations, and recommended workflows instead of hiding the messy parts.

Use /app if you want the full multi-carrier workbench in one place. Use the image, audio, or video pages if you want a guided page with the relevant tool embedded directly in context.

FAQ
Frequently asked questions
Common questions about Stego Studio and how to use it.
What can I do with Stego Studio?
You can hide text inside images, audio files, and video files, or extract text from files that were previously encoded.
Where should I start?
If you already know your carrier type, go straight to the image, audio, or video page. If you want the all-in-one tool, open the main app.
Which medium is best?
It depends on the workflow. Images are good for straightforward visual assets, audio is useful for WAV or compatible media exchanges, and video is best when you specifically need a video container as the carrier.
