Isteg lets you hide any zip file into an image

Isteg is a freeware tool that lets you hide a zip file into an image file - useful when you want to hide some secret information or want to send sensitive information over a network.

Isteg is a portable tool so no installation required. Just run it, select an image, then a zip file (Win zip / 7zip) and click ‘Hide it’ button. It will create a new image on the same directory of your original image file.

The program has no option to recover the embedded zip file. To recover your file, simply change the extension of your image file just created. That is, if your image is wallpaper.jpeg, just change the extension to That’s all.

Even though the tool lets you hide any file into an image, you can only recover zip files properly. Download Isteg.


  1. Change the extension back to zip the file is useless.
    I tried with 7zip to recover the file.
    You simply ask the extraction of the image file and it works perfectly. (Do not ask me how come). Also my exe-file was more than 4 MB and was reduced to an image of 2.5 MB (?).
    Thank you for the info!

  2. @Thanks for the info, but I couldn't find a way to extract the image file (JPEG) as mentioned above.

  3. Anonymous to anonymous
    I summarizes :
    1) the new image created with the program is in the folder of the original image. His name will be preceded by "New";
    2) open 7zip (freeware) or Winzip (fee) - it seems to work only with these two (see the site of the author) - , select the "new" image file (JPEG) and ask to extract.
    3) a new directory is created at the point of extraction, containing your exe or other- file.
    Simple, right ?
