Is Base64 encoding safe for emoji and accented characters?

Yes. This tool uses UTF-8 encoding before Base64, so emoji, accents, and non-Latin characters are preserved exactly when you encode and decode them.

Is my text sent to any server?

No. All encoding and decoding happens entirely in your browser using JavaScript. Nothing you type is ever uploaded or stored on a server.

What is the difference between encoding and encryption?

Encoding transforms data into another format that anyone can reverse, such as Base64 or hex. It is not secret. Encryption protects data with a password so only the right person can read it.

What formats can I convert between?

Base64, URL encoding, HTML entities, hexadecimal, binary, ROT13, and Morse code. Each supports two-way conversion, and the tool can auto-detect the format of pasted text.

Is this encoder decoder free?

Yes, it is completely free with no signup or registration required.

About These Formats

Base64 — Encodes any text or binary-style data into safe A–Z, a–z, 0–9, +/ characters. UTF-8 safe, so emoji and accents survive.
URL Encoding — Percent-encodes characters that are not safe in web addresses and query strings (spaces become %20).
HTML Entities — Converts characters like <, >, & and quotes into entity codes so text displays literally in HTML.
Hexadecimal — Shows each byte of the UTF-8 text as a two-digit hex value.
Binary — Shows each byte of the UTF-8 text as 8 bits.
ROT13 — A simple letter-rotation cipher; running it twice returns the original.
Morse Code — Translates letters, numbers and common punctuation to dots and dashes.

Privacy: Everything runs in your browser. No text is ever sent to a server. Encoding is not encryption — it is reversible by anyone.

How to Use This Tool

Choose a format — Pick Base64, URL, HTML entities, Hex, Binary, ROT13, or Morse code.
Pick a direction — Encode turns plain text into the format; Decode turns it back into plain text.
Type or paste — Enter text in the Input box. The Output updates live as you type.
Copy, download, or swap — Copy or download the result, or click Swap to feed the output back in for chained conversions.
Auto-detect — Turn on auto-detect to let the tool guess the format of pasted encoded text when decoding.

Common Questions

Will emoji and accents survive Base64? Yes — the tool encodes UTF-8 first, so characters like é, ñ, and 😀 round-trip perfectly.
Is encoding the same as encryption? No. Encoding is reversible by anyone. For password-protected secrecy, use an encryption tool instead.
Is my text uploaded anywhere? No. All conversion is done locally in your browser with JavaScript.
