Encode and decode Base64, URLs, JWT, hex, HTML entities, binary and Morse — text or files — all without uploading anywhere.
Encoding tools
- Base64 encoder / decoderEncode text or files to Base64 — or decode Base64 back to text and binary files. Standard and URL-safe alphabets.
- URL encoder / decoderPercent-encode or decode URLs and query parameters. Choose between component, full URI, or form (x-www-form-urlencoded) variants.
- JWT decoderDecode a JSON Web Token to inspect its header, payload, and signature — entirely in your browser. Signatures are NOT verified.
- Hex encoder / decoderEncode any text into hex (UTF-8 byte sequence) or decode a hex string back to text. Separator and case configurable.
- HTML entities encoder / decoderEncode special characters to HTML entities (named, numeric or hex) or decode entities back to characters.
- Binary encoder / decoderConvert text to its UTF-8 binary representation (8 bits per byte) — and back.
- Morse code encoder / decoderTranslate text to Morse code (international) and back. Optional audio playback through your speakers.
