Blaze Secret Message — Encode / Decode

Blaze Secret Message

Encode hidden text into a PNG image (LSB steganography). Save the PNG and decode on any device. Optional password encryption included.

Encode
Decode
Allowed: PNG recommended. Avoid JPEG (it will destroy hidden bits).
Drag & drop an image here or click "Choose image"
Capacity: —
Tip: After encoding, download the PNG file to your device. Do not upload to a platform that converts it to JPEG — that will remove the hidden message.

How it works

This page uses LSB (least significant bit) steganography. We write bits of your secret message into the lowest bit of the red/green/blue channels of pixels. Because these are the least significant bits, the visual change is imperceptible for normal viewing.

Payload format

Header: ASCII "BLAZESTG" (8 bytes) Version: 1 byte (0x01) Flags: 1 byte (bit0 = encrypted) Length: 4 bytes (big endian) — length of message data in bytes [If encrypted] Salt (16 bytes) + IV (12 bytes) used with PBKDF2+AES-GCM Message bytes (UTF-8, or AES-GCM ciphertext if encrypted)

Important notes

  • Use PNG. JPEG and many social platforms use lossy compression that destroys the hidden bits.
  • Capacity depends on image size. A 1000×1000 image can hold roughly ~375 KB when using 3 LSBs per pixel (R,G,B).
  • Encryption is optional — use a strong passphrase if you want confidentiality.
  • Encoded PNG must remain unmodified (no resizing/compression) to decode reliably.

Integration

Copy the entire HTML into a Blogger post in the HTML editor (not the Visual editor). If Blogger auto-optimizes images or converts inline images, instruct readers to download the encoded PNG and decode locally — do not rely on images hosted by third-party CDNs which may change the file.

Developer notes

If you want to host the encoder only (no file download), the code can be trimmed to keep just the embed flow. If you want mobile-friendly copy/paste behavior, we support the paste event in the decode panel.
