Binary Translator

How does this work?

Every character on your keyboard has a numeric code (its Unicode code point). The letter A is 65, lowercase a is 97, the space character is 32. To encode text as binary, each of those numbers is written in base 2 and padded to 8 bits. So Hi becomes 01001000 01101001.

Decoding is the reverse

Split the input on whitespace, read each chunk as a base-2 number, look up the matching character. The decoder here is forgiving — it strips anything that is not a 0 or 1 before parsing, so binary you copied from a noisy source will still decode cleanly.

When is this useful?

Mostly for fun, learning, and puzzles. Binary encoding shows up in escape rooms, CTF challenges, computer science homework, and as a hidden-message gimmick in social media posts. It is not encryption — anyone can decode it — but it does make text unreadable at a glance.
