Encode any text into binary (base-2) byte sequences with visible separators. See exactly how computers store letters — local encoding, free, no signup.
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 images to Base64 data URIs for CSS embedding and API payloads. Inline a logo without extra requests — local encoding, free, no signup.
Convert numbers between binary, octal, decimal, and hex with bitwise views. Read 0xFF as 255 instantly — local math, free, no signup.
Analyze each character to see its Unicode code point and ASCII/non-ASCII status. Debug mojibake with byte-level views — free, local, no signup.
Count characters, letters, digits, spaces, and punctuation as you type — totals with and without spaces plus an upper/lowercase split. Fit a 280-character post exactly — free, local, no signup.
01000001 — 8 bits: 64+1. Each character maps through its code point; the tool shows byte boundaries explicitly.
Yes — UTF-8 multi-byte sequences encode fully (é becomes two bytes). Byte counts exceed character counts for non-ASCII text.
CS classes demonstrate encoding live: type names, watch bits. Separators make nibble structure visible.
No — encoding runs locally in your browser. Text never leaves your device.
Binary to Text
Decode binary strings back to readable Unicode text with strict validation. Recover messages from bit dumps — local decoding, free, no signup.
Hex ↔ ASCII Converter
Convert between hexadecimal bytes and ASCII text. Supports custom delimiters and real-time bidirectional conversion. Code never leaves your device — formatting and validation run locally in your browser.
