Free Hex, Bytes & Text Converter that works offline
Inspect the exact UTF-8 bytes behind text or decode a hexadecimal byte sequence into readable characters.
What this hex, bytes & text converter does
Hexadecimal writes each byte with two base-16 digits. Because UTF-8 characters may occupy multiple bytes, visible character count and byte count can differ.
How to use the Hex, Bytes & Text Converter
- Enter or paste Unicode text or a sequence of two-digit hexadecimal bytes into the tool.
- Adjust the available options so they match the format and result you need.
- Choose Convert text and hexadecimal bytes and review formatted hex bytes or decoded UTF-8 text before using it.

Private processing and offline access
This tool does not submit your input to a conversion server. Processing takes place inside the browser using local JavaScript and standard Web APIs. After the PWA has been installed or cached, the page and its core features remain available without an internet connection. Closing or clearing the page removes unsaved input; the tool does not create an account or cloud history.
Tips for accurate results
- Hex is not encryption.
- Use a dedicated parser for structured binary formats.
- Invalid UTF-8 bytes are reported rather than replaced.
