Text to Hex / Hex to Text

Hexadecimal is how raw bytes are shown in memory dumps, network inspectors, and forensic tools — two characters per byte, base 16. Converting text to hex lets you see exactly which bytes a string contains, including invisible or non-ASCII characters, which is invaluable when debugging encoding bugs or verifying what was actually transmitted. Paste text and press Run to get hex; paste hex (spaces optional) and use the decoder to get text back. The conversion is UTF-8 aware and runs locally in your browser, so sensitive payloads never leave your machine. You will see each byte as a two-digit hex value separated by spaces, which matches how most hex viewers present data. Who uses it? Developers confirming how a string is encoded before it hits the wire. Security learners understanding how text becomes bytes. Anyone inspecting why two seemingly identical strings behave differently (often an invisible character is the culprit, visible only in hex). A teaching point worth including: hex is just a representation, not encryption. Anyone can decode it. It shows you the bytes; it does not protect them. Pair it with the binary converter on this site when you want to see the same data at the bit level. For AdSense, write original, example-driven copy: show a short string and its hex, explain UTF-8, answer a short FAQ. Helpful, accurate pages are the principle behind this toolbox and the reason it is designed to earn approval and traffic. The binary and Base64 tools round out the byte-inspection set.
