Free Online Decoders
When data arrives encoded — a hex dump from a debugger, binary from a wire capture, ASCII codes from a legacy system, or HTML entities in scraped markup — these decoders turn it back into readable text instantly. Paste hexadecimal byte pairs, space-separated binary octets, ASCII or octal code values, or entity-escaped HTML, and get the original string with no manual table lookups.
Each decoder validates its input and points out malformed values instead of failing silently. All processing happens in your browser, so encoded payloads from production systems never leave your machine. Free, instant, and no sign-up required.
