What this tool does

Convert text to binary and binary back to text, right in your browser. Pick UTF-8 (the modern default, handles Chinese / Japanese / emoji), strict ASCII (errors on bytes above 127, useful for teaching), or UTF-16 big-endian (2 bytes per BMP code unit). Group output in 8, 16, or 32-bit chunks, with space or 0b prefix separators — or no grouping at all for a raw bit stream. The decoder ignores whitespace and 0b prefixes, reports the exact position of any non-binary character, and tells you precisely how many bits your input is off by when it's not byte-aligned. Round-trips emoji and Han characters losslessly. No uploads, no tracking, no signup.

How Text to Binary Converter fits into your work

Use it for quick browser-side encoding, decoding, hashing, token checks, and share-safe transformations.

Encoding jobs

  • Checking small payloads, tokens, hashes, and encoded values quickly.
  • Preparing values for APIs, URLs, docs, or support tickets.
  • Avoiding account-based tools when the input might be sensitive.

Encoding checks

  • Do not paste live secrets unless you are comfortable with local browser handling.
  • Confirm whether the operation is reversible before sharing the result.
  • For hashes, compare the exact algorithm and casing expected by the receiver.
