Hex to ASCII Converter

Paste hex byte pairs — spaced out like 48 65 6c 6c 6f or run together like 48656c6c6f — and read the plain-text message they encode.

What is the Hex to ASCII Converter?

The Hex to ASCII Converter decodes hexadecimal byte values back into readable text. It accepts both common formats: byte pairs separated by spaces or commas, and one continuous unbroken hex string, so you don't need to reformat data copied from a network capture, hex editor or API payload before decoding it.

How It Works

The converter strips any spaces or commas from each line, checks that what remains is a valid, even-length hex string, then splits it into two-character byte pairs. Each pair is parsed as a byte value and the full byte sequence is decoded as UTF-8 text, so accented characters and other multi-byte sequences come through correctly rather than as garbled symbols.

Real-World Use Case

Reverse-engineering a protocol or reading a raw hex dump from a packet sniffer often leaves you staring at strings like 47455420 2f20485454502f312e31 — pasting that in here immediately reveals it says GET / HTTP/1.1 instead of decoding it byte by byte in your head.

Frequently Asked Questions

Does it matter if there are spaces between the byte pairs?

48 65 6c 6c 6f and 48656c6c6f decode to the exact same text — the converter strips whitespace and commas before splitting the string into byte pairs.

What happens with an odd number of hex digits?

That line is flagged as invalid, since a byte always needs exactly two hex digits — an odd-length string means a digit is missing or extra somewhere.

Can it decode more than one message at once?

Yes. Put each hex message on its own line and every line is decoded independently, with its own line in the result box.
