About the Online Base64 Encoder/Decoder

Our Base64 Encoder/Decoder is a versatile online tool for working with Base64 encoding. It allows you to seamlessly convert plain text and images into a Base64 string (encode) and revert Base64 strings back to their original form (decode). This tool is essential for web developers, programmers, and anyone needing to transmit data over media designed to handle only text, such as in email attachments or for embedding binary data like images directly into HTML, CSS, or JSON files. Whether you need to encode a string to Base64, decode a Base64 string, or convert an image to a Base64 data URI, our tool provides a simple and efficient solution.

How to Use the Tool

  1. Select the desired conversion tab: 'Text to Base64', 'Base64 to Text', 'Image to Base64', or 'Base64 to Image'.
  2. For text to Base64 encoding, enter your text in the input field and click 'Encode'. The tool supports UTF-8 and other character sets.
  3. For Base64 to text decoding, paste your Base64 string into the input area and click 'Decode' to see the original text.
  4. For image to Base64 conversion, simply drag and drop an image file or click to upload. The tool will generate a Base64 data URI.
  5. For Base64 to image decoding, paste a valid Base64 image string and click 'Decode' to preview and download the image.
  6. Use the 'Copy' button to quickly get the result to your clipboard.

Frequently Asked Questions

Q: What is Base64 encoding?

A: Base64 is an encoding scheme that converts binary data into a radix-64 representation, which is made up of 64 basic ASCII characters. It's used to ensure that data remains intact without modification during transport through text-only channels.

Q: Is Base64 the same as encryption?

A: No, Base64 is an encoding method, not encryption. It is easily reversible and does not provide security. For data protection, use encryption algorithms like AES.

Q: How to convert image to Base64?

A: You can use the 'Image to Base64' tab. Upload your image, and the tool will automatically convert it into a Base64 string, which you can use in HTML `<img>` tags or CSS `background-image` properties.

Q: Why is my Base64 string not decoding?

A: This can happen if the string is not a valid Base64 sequence. A valid string should only contain `A-Z`, `a-z`, `0-9`, `+`, `/` characters, and might have `=` for padding at the end. Check for any invalid characters or corruption in the data.

Q: What is a Base64 data URI?

A: A Base64 data URI (or data URL) is a scheme that allows you to embed files, like images, inline in web pages. It starts with `data:image/[MIME_type];base64,` followed by the Base64-encoded data.
