Base64 Encoder
Encode/decode Base64 strings
How to Use the Base64 Encoder/Decoder:
- 1 Enter the text you want to encode or the Base64 string you want to decode into the "Input Text" area.
- 2 Click "Encode" to convert your text to Base64, or "Decode" to convert Base64 back to text.
- 3 The result will appear in the "Output" area.
- 4 If decoding fails (e.g., due to an invalid Base64 string), an error message will be shown.
- 5 Click "Copy" to copy the output to your clipboard.
What is Base64 Encoding?
Base64 is a group of binary-to-text encoding schemes that represent binary data in an ASCII string format by translating it into a radix-64 representation. In simple terms, it's a way to encode any data (like text, images, or files) into a limited set of common, readable characters.
This is particularly useful when data needs to be stored or transferred over media that are designed to deal with text. Common use cases include:
- Embedding Images in HTML/CSS: Using a "Data URI" (e.g., `data:image/png;base64,...`), you can embed an image directly into a webpage's code, avoiding an extra HTTP request. You can use our Image to Base64 tool for this.
- Email Attachments: Base64 is used in the MIME standard for email attachments.
- Storing Binary Data in Text Formats: It's a common way to store binary data in text-based formats like JSON or XML.
How It Works
Our tool correctly handles Unicode (UTF-8) characters for both encoding and decoding, ensuring that special characters and emojis are processed accurately. All operations are performed client-side in your browser, so your data is never sent to our servers.
