The short answer

Why use Steganography?

Browser APIs can handle many small file and device jobs without another upload step. The tool also shows a clear message when a permission or format is unavailable.

Steganography focuses on encrypting text and hiding it inside the pixels of a PNG. The task uses browser storage, permissions, cryptography, or clipboard features. Sensitive values are not added to analytics.

The selected file stays in this browser tab and is released when you leave the page. Permissions and supported features differ by browser. Camera, clipboard, screen capture, and geolocation require HTTPS and a user action.

Working limit: File tools use the 50 MB image or 100 MB document limit; device tools depend on browser permissions. Watch the preview at full size before you save.

Frequently asked questions

If you cannot find what you are looking for, write us a message and we will get back to you.

What should I check before saving with Steganography?

Permissions and supported features differ by browser. Camera, clipboard, screen capture, and geolocation require HTTPS and a user action.

Does my file get uploaded?

No. Processing happens in your browser and the working file is cleared when you leave the page.

Can I use Steganography on a phone?

Yes, in a current mobile browser. Large files may need a desktop because phones have tighter memory limits.

Will Steganography overwrite my original file?

No. The browser reads the source and creates a separate result for download.

Why might the Steganography result look different in another app?

Browsers and apps may decode formats or scale previews differently. Compare the downloaded file at 100% zoom and check its actual dimensions.

Is Steganography free to use?

Yes. There is no signup to run it. Processing stays in this browser tab for local tools. ExtractPics does not put this page behind a paywall.

How does Steganography work?

The browser reads your file, encrypting text and hiding it inside the pixels of a PNG, and writes a separate result. Close the tab and the working buffers are released.

What can I put into Steganography?

Supported input is listed on this page. Limit: File tools use the 50 MB image or 100 MB document limit; device tools depend on browser permissions. If the file is larger, shrink or split it first.

How do I save the result from Steganography?

Use the download (or copy/print) control in the workbench. Output: A downloaded file, copied value, live preview, decoded text, or browser dialog. The original file on disk is not replaced.

Why did Steganography fail or look wrong?

Check the preview at the size you will actually use. Try a current Chrome or Edge build, a smaller file, and a desktop if the phone ran out of memory. If a format is listed as unsupported, this tool will not invent a decoder for it.

Will Steganography keep a copy of my work?

No. There is no cloud library of your exports. Download or copy the result before you close the tab.
