Do you need a fast and reliable way to convert text or small files into Base64 format and decode them back? Our Base64 Encoder / Decoder app is a simple, modern, and responsive web tool that performs Base64 conversions instantly right in your browser — no downloads or installations required.
🔍 What Is Base64 Encoding?
Base64 is a method of converting binary data (like images, files, or special text characters) into readable text format. It’s often used in web development, email attachments, and APIs to safely transmit data without corruption or loss of information.
For example, when you encode an image in Base64, it becomes a long text string that can be embedded directly into HTML or CSS files. The Base64 Decoder can then easily convert that text back into its original form.
⚙️ How the App Works
- Encode Text: Type or paste your text into the input area, then click “Encode” to convert it into Base64 format.
- Decode Text: Paste Base64-encoded data into the box and click “Decode” to get the original text back.
- File Support: Upload a small file (like an image or document) to convert it to Base64 and view or copy the encoded output.
