What is Text to Base64 encoding?
Base64 encoding converts text into a compact string made up of only letters, numbers, and a couple of symbols. Developers use it to embed data safely inside URLs, JSON payloads, HTML data attributes, email headers, and configuration files — anywhere that raw or special characters might break the format.
Paste your text above and get the Base64 string instantly. The tool encodes with UTF-8, so emoji and international characters convert correctly, and nothing you type is uploaded — it all happens in your browser.
Frequently asked questions
What is Base64 encoding?
Base64 is a way of representing binary or text data using only 64 printable ASCII characters. It's commonly used to safely embed data in URLs, JSON, emails, and data URIs where certain characters would otherwise cause problems.
Does this support special characters and emoji?
Yes. The encoder uses UTF-8, so accented letters, non-Latin scripts, and emoji are encoded correctly.
Is my text sent to a server?
No. Encoding happens entirely in your browser, so your text never leaves your device.
