Turn UTF-8 text into hex or binary dumps, decode hex back to text, map characters to ASCII/Unicode code points, or convert integers between binary, octal, decimal and hex—all locally.
Hex, binary & ASCII converter — private
Developers in DE/FR/ES/IT search daily for hex-to-text, binary converters and ASCII tables. Convert UTF-8 text to hex or binary, peel hex dumps back to text, map characters to code points, or switch integer bases—entirely in your browser.
- Text ↔ Hex for debug dumps and firmware.
- Text ↔ Binary for teaching and bit-level checks.
- ASCII / Unicode codes for European characters beyond 7-bit ASCII.
- Need Base64 instead? Use the Base64 converter or Hex to Base64.
よくある質問
Is hex encoding the same as Base64?
No. Hex uses two characters per byte (0–9, A–F). Base64 uses four characters per three bytes. Use our Base64 converter when APIs expect Base64.
Does this support European characters?
Yes. Text modes use UTF-8, so accents (é, ü, ñ, ł) and Cyrillic encode correctly to multi-byte hex.
