How to Base64 Encode Text
Published September 11, 2026 · 2 min read
Base64 encoding turns arbitrary text or binary data into a safe, ASCII-only text representation — commonly needed for embedding data in URLs, JSON, or authentication headers. This encodes any text you provide directly in your browser.

Frequently asked questions
No — base64 is a reversible encoding, not encryption. Anyone can decode it back to the original text; it provides no confidentiality or security on its own.
Yes — the text is encoded as UTF-8 bytes first, so any Unicode text, including emoji, encodes and decodes correctly.
Use the companion Base64 Decode tool to convert an encoded string back into readable text.
Because encoding happens instantly in your browser, this is a quick way to prepare text for a URL parameter, config file, or API payload without any external service.
