Text to Binary Converter — Free Online Tool 2026
Text to binary conversion encodes each character as an 8-bit binary number using ASCII (or UTF-8 for extended characters). The letter 'A' is 01000001, 'B' is 01000010, and so on. Binary is the fundamental language of computers — all text, images, and data are ultimately stored as sequences of 0s and 1s. Our text to binary converter handles all ASCII characters plus UTF-8 extended characters, and shows binary, hexadecimal, and decimal representations simultaneously. No sign-up required — your data never leaves your browser. Works instantly on desktop, tablet, and mobile. Completely free with no daily usage limits, no watermarks, and no account needed. Trusted by students, professionals, and businesses worldwide. FixFlowHub is a browser-based toolbox with 120+ free utilities covering PDF, image, text, calculator, and productivity tools.
Frequently Asked Questions
How does text to binary conversion work?
Each character is converted to its ASCII decimal value, then that number is written in binary (base-2). 'A' = ASCII 65 = binary 01000001.
What is 'Hello' in binary?
Hello in binary: H=01001000, e=01100101, l=01101100, l=01101100, o=01101111. Full: 01001000 01100101 01101100 01101100 01101111.
Why do computers use binary?
Binary uses only 0 and 1 — which map to off and on electrical states in transistors. This simple two-state system is reliable and easy to implement in physical hardware.
