Encode text to Base64 or decode Base64 to text instantly.
Base64 is a binary-to-text encoding scheme that converts binary data into ASCII characters. It is commonly used for embedding images in HTML, encoding email attachments, and transmitting data in URLs.
No. Base64 is an encoding, not encryption. It transforms data into a different format but does not protect it. Anyone can decode Base64 back to the original data.
Yes. Our Base64 tool fully supports UTF-8 encoded text, including special characters, emojis, and non-Latin scripts.
Standard Base64 uses + and / characters which are not URL-safe. Base64URL replaces them with - and _ to make the output safe for use in URLs and filenames.
Base64 is used in data URIs (embedding images in CSS/HTML), email attachments (MIME), JWT tokens, API authentication headers, and storing binary data in JSON or XML.
