ASCII / HEX Converter Documentation

Convert text to its hexadecimal byte representation, or decode hex back into readable ASCII text.

SiteIndex reads each character's byte value and renders it as two-digit hexadecimal, or parses hex pairs back into their ASCII characters, with instant two-way conversion.

• Inspect the raw byte values behind a short text string.
• Decode a hex-encoded value back into readable text.
• Prepare byte sequences for low-level protocol or firmware work.

Input

Text, files, or values entered in the browser, depending on the tool.

Output

A result shown in the browser that can be reviewed or copied where supported.

• This is a text helper, not a binary-file editor. Verify the implementation's encoding against the destination protocol before using non-ASCII content.

Inputs for this browser-side tool are processed locally and are not sent to SiteIndex. Normal page analytics may still be collected as described in the Privacy Policy. Read the Privacy Policy.
