Encode text to Base64 or decode Base64 to text instantly. Support for text, images, and files.
Base64 is a binary-to-text encoding scheme that converts binary data into a printable ASCII string format. It's commonly used to encode binary data (like images) for transmission over text-based protocols like email or embedding in HTML/CSS.
Base64 encoding increases file size by approximately 33%. It's encoding, not encryption - data can be easily decoded. Don't use it for sensitive information.
No, Base64 is not encryption. It's simply encoding that can be easily decoded. Never use it to protect sensitive data.
Base64 uses 6 bits per character instead of 8 bits per byte, resulting in approximately 33% larger output.
Standard Base64 uses + and / characters which have special meaning in URLs. URL-safe Base64 replaces them with - and _ to be safely used in URLs.
