hiddenPix is a browser-based image encryption tool for private photo sharing. Scramble images into unreadable pixel art, or hide private photos inside ordinary-looking pictures. All processing runs locally in your browser. When you share via a link, only the encrypted file is uploaded — it expires after 24 hours.
hiddenPix encrypts images in two ways. Scramble Mode shuffles pixel blocks using a password-derived key — the result looks like abstract noise. Steganography Mode embeds a private image into the pixels of a cover photo — the output looks like an unremarkable picture. Without the password, the hidden content cannot be recovered. Both modes run entirely in your browser. It is not cloud storage. It is not a messaging app. It is a small, focused tool for keeping private photos out of casual view.
Most encryption is obvious. A password-protected ZIP, a PGP message, an encrypted archive — these announce that something is hidden. Private image encryption via social steganography works differently. The hidden content exists openly, in public, disguised as something mundane. A photo in a cloud album. A post on social media. An image in a group chat. Only someone with the password knows there is a second layer. The result is public-but-private content that blends into the noise of the internet.
With hiddenPix partial encryption, you draw a curve across the image to split it in two: one side stays exactly as it is, the other is scrambled into unrecognizable pixel blocks. Show what you want shown, hide what must stay hidden — perfect for teaser previews, before-and-after reveals, or encrypting only the most sensitive region of a photo. Everything still runs locally in your browser, and the recipient restores the full original by entering the password through the share link.
Everything happens on your device. Images are never uploaded during processing — encryption and embedding run entirely in the browser, and your password is never stored. When you share an encrypted image via a link, only the already-encrypted file is uploaded, and it is auto-deleted after 24 hours. The server never receives your password or your original images, so nobody — including us — can decrypt the shared file.
Traditional encryption creates archives, ciphertext, or locked files. The encryption is visible — anyone can see that something is protected. This works for private storage but draws attention in public spaces. Encrypted files look suspicious in social feeds, cloud albums, and messaging apps. They are not designed for image encryption.
hiddenPix image encryption hides the fact that anything is hidden at all. The output looks like a normal image — shareable anywhere without raising questions. The encryption is visual, the disguise is the point, and the result is designed for the social internet. It is image encryption that does not look like encryption. Private image encryption for the real world.
hiddenPix is a browser-based image encryption tool with two modes. Scramble turns an image into unrecognizable pixel noise; Steganography hides a private image inside an ordinary-looking photo. All processing runs locally in your browser — your original images and password are never uploaded.
Scramble Mode derives a seed from your password, generates a pseudorandom Fisher-Yates permutation and shuffles the image's pixel blocks (4×4 up to 64×64) accordingly. Steganography Mode XOR-encrypts your secret file with your password and embeds the result in the least significant bits of the cover image's RGB channels (1 bit per channel). Honest caveat: this is lightweight visual protection — not AES-GCM or any audited cryptographic standard, and there is no integrity or authentication layer. If you need cryptographic guarantees, use a dedicated tool such as age, 7-Zip (AES-256) or VeraCrypt.
We make no such promise. Without the password the hidden content cannot be recovered, and visually the output looks like an ordinary image. But steganalysis tools can flag LSB-embedded images, and scrambling preserves statistical features such as the color histogram. Treat hiddenPix as everyday privacy protection against curious eyes — not as a defense against a determined attacker.
Be careful: most platforms re-compress images on upload. Re-encoding destroys LSB-embedded data — the hidden image becomes unrecoverable — and degrades scrambled images as well. Always send the encrypted PNG as a file or "original image" (a chat file attachment or a cloud drive link), and confirm the recipient can decrypt it before relying on it. The share link is the safest route because it serves exactly the file that was uploaded.
Encryption and decryption always run locally in your browser; nothing is uploaded while processing. When you generate a share link, the already-encrypted file is temporarily uploaded to cloud object storage so the recipient can download it. It is automatically deleted after 24 hours. The server never receives your password, your original image or any unencrypted data, so nobody — including us — can decrypt the shared file. Transfer metadata such as access logs remains subject to the hosting provider's policies.
It depends entirely on your password. The key is derived from your password with a simple hash — there is no key stretching — so short or common passwords can be guessed quickly. Use a long, random password and send it through a different channel than the image.
The share link stops working and the file is permanently deleted from the server. There is no backup and no recovery. Decrypt and save anything you want to keep before the link expires.
Whenever you need provable security: legally sensitive material, anything a motivated adversary is actively after, or data with compliance requirements. Use audited encryption tools like age, GPG, 7-Zip or VeraCrypt for those. hiddenPix is designed for everyday privacy — keeping personal photos out of casual view.
