Frequently Asked Questions
Base64 is a way of representing binary or text data using only 64 printable ASCII characters, which makes it safe to include in places (like URLs, JSON, or emails) that don't reliably handle raw binary data.
No — Base64 is encoding, not encryption. Anyone can decode it back to the original text instantly, so it should never be used to protect sensitive information like passwords.
Standard Base64 uses characters (`+`, `/`) that have special meaning in URLs; URL-safe Base64 replaces them with `-` and `_` so the encoded text can be used directly in a URL without extra escaping.
No — encoding and decoding both happen entirely in your browser.
Yes — paste a Base64 string and decode it back to plain text instantly.
It's commonly used for authentication tokens, embedding small files or images inside text-based formats, and safely transmitting binary-like data through systems designed for plain text.

About Base64 Encoder
Base64 Encoder converts plain text into Base64 format, and decodes Base64 back into readable text — commonly needed when embedding data in a URL, working with authentication tokens, encoding data for an API request, or including small binary data (like an image) directly inside a text-based format such as HTML or JSON. URL-safe Base64 encoding is also supported for text that needs to go directly into a URL or query string.
