The hidden
layer
My first projects were steganography tools — iSteg hid text inside images, aSteg hid files inside audio. This page is their browser-native descendant. Everything runs locally — nothing you put here leaves your machine.
01 — Hide text in an image
02 — Reveal text from an image
03 — Decode hidden text from… text
Some text carries invisible zero-width characters between its letters. Paste a suspicious sentence here. The homepage might be a good place to start.
How it works: images use least-significant-bit encoding across RGB channels; text uses U+200B/U+200C zero-width characters as binary. Read the write-up.
