You can save the resulting carrier file and open it any default file viewer of your OS. including ios, macos, windows etc.

Regarding being detected, like anything else in security it is always a cat and mouse game.

for anyone who wants to try a consumer grade stegongraphy in browser. I built some thing here. Its free and loads a static page with a wasm binary. Once the page loads everything is handled in the browser.

You provide a carrier file (currently .mp4, .pdf, .jpeg or .png ) and impregnate it with an entire encrypted file system with a full viewer and gallery mode. Also supports streaming, so you can actually encrypt a a full blueray movie and run range requests.

Locally running fully working steganography in the browser.

Create and insert entire files into pngs, mp4, pdfs and jpgs. The site is a static website that loads a wasm bin that does everything in browser with wasm. So no login, or network calls.

Essentially impregnate images and videos that open normally in your browser, but have a full file system with a full gallery mode for images, pdfs and images inside. videos do seek and stream so even if you embed a 4GB video file, it opens quite fast and just works.
