Encode text to Base64 or decode Base64 strings back to plain text. Supports UTF-8 characters. Fast and private.
Base64 is a binary-to-text encoding scheme that represents binary data as a string of ASCII characters. It is commonly used to embed binary data in text-based formats like JSON, XML, HTML, and email.
Base64 is commonly used for embedding images in CSS or HTML, sending binary data in JSON APIs, encoding email attachments (MIME), and storing binary data in text-based databases or configuration files.
Yes. Base64 encoding increases the data size by approximately 33%, because every 3 bytes of binary data are represented as 4 ASCII characters.
No. Base64 is an encoding scheme, not encryption. It does not provide any security. Anyone can decode a Base64 string back to its original content. Do not use Base64 to protect sensitive data.
