Instantly encode text to Base64 or decode Base64 strings back to plain text. Perfect for encoding data, working with APIs, or debugging.
Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format. It's commonly used to encode data for transmission over media that only supports text, such as email or JSON.
Base64 encoding is useful for encoding binary data in JSON, embedding images in HTML/CSS, encoding email attachments, and working with APIs that require text-based data transmission.
No, Base64 is encoding, not encryption. It's a reversible transformation that doesn't provide security. Anyone can decode Base64 data if they have access to it.
Base64 uses 64 characters: A-Z, a-z, 0-9, plus (+) and slash (/). The equals sign (=) is used for padding at the end of encoded strings.
