Convert hexadecimal encoding into readable text

This tool converts hexadecimal encoding into readable text. It provides flexible options so you can convert every hexadecimal sequence in your text, convert only those you specify, convert all except allowed sequences, or replace them with a custom placeholder. Simply enter your hex-encoded text, choose the processing mode that suits your needs, and process your text.

Processing Modes:

Convert All Hexadecimal Sequences
Finds every contiguous block of hex digits (at least two digits) in the text and converts them to readable text.

Convert Only Specified Hexadecimal Sequences
Converts only the hexadecimal sequences you specify. Enter a comma‑separated list of hex sequences (e.g., 48656c6c6f,576f726c64).

Convert All Except Allowed Hexadecimal Sequences
Converts every hexadecimal sequence except those you explicitly allow. Enter a comma‑separated list of hex sequences (e.g., 48656c6c6f).

Replace Hexadecimal Sequences with a Placeholder
Replaces every hexadecimal sequence with a custom placeholder string instead of converting. Enter the placeholder text below.
