How to use Convert Hexadecimal to ASCII
- 1. Paste your hex bytes. Paste space separated hexadecimal byte values like 48 69 into the input pane. Two digit pairs are read as a single byte across the full 00 to FF range.
- 2. See each byte parsed. Each two digit hex value is parsed as base 16 and mapped to its ASCII character. The tool works through the whole hex string in the order it was pasted.
- 3. Copy the decoded text. Copy the resulting text from the output pane once the hex string has been converted. Paste a new hex string to decode another value right away.
When to use Convert Hexadecimal to ASCII
Convert Hexadecimal to ASCII decodes hex byte values, the format used in hex editors, memory dumps and low level debugging tools, into the readable text they represent. Reading a long hex dump by converting each pair of digits by hand is slow, so this tool converts the whole string in one pass.
- Reading a hex editor selection. You highlighted a range of bytes in a hex editor while inspecting a binary file and want to know if it spells out a readable string. Pasting the hex values here shows the text immediately.
- Decoding a hashed or encoded token. A session token, API key fragment or encoded parameter appears as hex in a URL or log file. Converting it reveals whether it is plain text underneath rather than a genuine hash.
- Inspecting malware or firmware strings. A reverse engineer scanning a binary for readable strings finds a suspicious hex sequence in the disassembly. Decoding it here confirms whether it is a command, URL or plain configuration text.
- Checking a network protocol field. A raw packet capture displays a field as hexadecimal rather than ASCII. Converting the bytes clarifies whether the field carries a text based value like a hostname or cookie.
