What's in Pro

  • Batch hide to .zip

    Hide the same message (optionally password-encrypted) into many cover images at once and download them as a single .zip. Any one member reveals the payload.

  • Invisible watermark

    Embed an imperceptible owner/ID signature into an image and detect it back without the original — for provenance and leak-tracking.

  • Steganography detector

    A chi-square LSB steganalysis heuristic plus a visual LSB-plane preview that flags likely hidden data in an image.

  • .hink cover format

    The self-describing, versioned HINK frame that wraps every payload so extraction is exact.

  • Ad-free

    Every ad disappears the instant you unlock.
