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.

Launch ToolFrequently Asked Questions
- Why does my decoded output look like gibberish?
- The bytes probably aren't plain ASCII — UTF-8 multi-byte sequences, binary data, or an odd-length input will shift every following value. Verify the source encoding and that hex/binary input has an even length or full 8-bit groups.
- Does the HTML decoder also convert entities like &?
- Yes — it uses the browser's own HTML parser, so named entities (&, <) and numeric entities (&) both decode correctly in the same pass.
