Encode text to Base64 or decode Base64 to text instantly. Supports UTF-8, URL-safe mode, and line wrapping β all free and private in your browser.
All processing happens in your browser. Your data never leaves your device.
Paste your text and click Encode to convert it to Base64, or paste Base64 and click Decode to get the original text back. The tool fully supports UTF-8 characters including emoji and non-Latin scripts.
Base64 encoding is commonly used in web development for embedding data in URLs, emails (MIME), data URIs, API tokens, and configuration files. This tool lets you quickly encode or decode without writing code.
Base64 is a way to represent binary data using only printable ASCII characters (A-Z, a-z, 0-9, +, /). It's commonly used to safely transmit data through text-only channels like email or URLs.
URL-safe Base64 replaces '+' with '-' and '/' with '_', and removes padding '=' characters. This makes the output safe to use directly in URLs and filenames without additional encoding.
Yes. The tool properly handles UTF-8 encoding, so you can encode and decode text in any language, including emoji and special characters.
No. Base64 is an encoding, not encryption. Anyone can decode Base64 data β it provides no security. It's designed for data transport, not data protection.
The tool validates the input and shows a clear error message if the Base64 string is malformed β for example, if it contains invalid characters or has an incorrect length.
