    Steganography Tool

    Stash secret texts and files inside ordinary images. Nobody suspects a thing. 100% free, always.

    Lock It Down

    Everything gets encrypted right in your browser before it even touches the image.

    Upload Your Image (JPG, JPEG, PNG)

    or drag & drop here

    JPG, JPEG, or PNG only — that's the deal

    Done!

    Pick your data type and drop an image to get started

    Hides text messages and literally any file type

    Wait — What's Steganography?

    It's the ancient art of hiding secrets in plain sight. Unlike encryption (which scrambles data), steganography hides the very fact that a secret exists. Normal-looking image. Hidden payload. Zero suspicion.

    We do it at the pixel level — your data is encrypted then buried inside image pixels. Supports JPG, JPEG, PNG — output always PNG. Completely invisible to the naked eye.

    All crypto runs on the Web Crypto API using AES-GCM. Same stuff banks rely on.

    What It Can Do

    Any file, any size, fully encrypted — yeah it hits different

    Locked Tight

    Your data gets encrypted before it even touches the image. Nobody's cracking that, period.

    Completely Invisible

    Data buried so deep in the pixels, nobody can tell — not even forensics tools.

    Any File, Any Format

    PDF, DOCX, ZIP, MP3 — if it's a file, you can hide it. No restrictions.

    End-to-End Encrypted

    Encrypted before embedding, decrypted only with the right key. We know nothing about your secrets.

    How It Works

    3 steps, zero drama

    Step 1

    Drop Your Image

    Pick any image as your cover (JPG, JPEG, PNG) — then choose what you're hiding: a text message or any file.

    Step 2

    Encrypt & Vanish

    Your secret gets encrypted end-to-end and tucked invisibly into the image pixels. File name and type? Preserved automatically.

    Step 3

    Share It Freely

    Download and share anywhere. Only someone with the right key can decode it — everyone else just sees a picture.

    So Who Actually Uses This?

    Secret Comms

    Send hidden messages without raising any red flags. Journalists, activists, privacy nerds — this one's for you.

    Digital Watermarking

    Embed invisible copyright info or metadata in your images. Proof of ownership — no one knows it's there.

    Password Stash

    Hide sensitive passwords or recovery codes inside a totally normal-looking image. Sneaky but genius.

    Covert Backup

    Tuck important files into images for legit backup purposes. Slips through content filters without a sweat.
