Convert between plain text and binary in both directions — encode text into its base-2 representation or decode binary strings back to readable text, byte by byte. Files are converted locally in your browser — nothing is uploaded.
Encode any text into binary (base-2) byte sequences with visible separators. See exactly how computers store letters — local encoding, free, no signup.
Decode binary strings back to readable Unicode text with strict validation. Recover messages from bit dumps — local decoding, free, no signup.
Convert numbers between binary, octal, decimal, and hex with bitwise views. Read 0xFF as 255 instantly — local math, free, no signup.
Encodes text or small files into Base64 strings and decodes them back with automatic MIME-type detection for binary safety. Code never leaves your device — formatting and validation run locally in your browser.
Encode text to Base32 or decode Base32 strings back — the alphabet TOTP apps and authenticator URIs use. Both directions, fully local.
Text is converted to binary using UTF-8 encoding. Each character is represented as its 8-bit binary equivalent (e.g., 'A' = 01000001).
Use spaces between 8-bit groups (e.g., 01001000 01100101). Commas are also accepted as separators.
Yes. UTF-8 encoding supports all Unicode characters including accented letters, emoji, and non-Latin scripts.
Paste the binary string to decode it back to readable text — both directions work in the same tool.
