Free Online Base64 Encoder & Decoder

Welcome to our versatile free online Base64 Encoder & Decoder tool! This utility is a must-have for web developers, designers, and anyone who needs to convert data to Base64 or decode Base64 strings. Whether you’re working with text snippets or embedding images directly into your code, our tool provides a fast, secure, and user-friendly solution.

What is Base64 Encoding?

Base64 is a binary-to-text encoding scheme that represents binary data (like images, audio, or entire files) in an ASCII string format. Its primary purpose is to safely transmit binary data over mediums that are designed to handle text.

Key Uses of Base64:

• Embedding Images: Commonly used to embed images in HTML (<img src="data:image/...">) or CSS (background-image: url("data:image/...")) to reduce HTTP requests.
• Data Transfer: Sending binary data (e.g., small files, encryption keys) in text-based protocols like email (MIME) or JSON.
• Obfuscation (Minor): While not encryption, it can make data unreadable to the casual observer.

Our Base64 converter simplifies this process, making it accessible even if you’re not a coding expert.

How Our Base64 Encoder & Decoder Works

Our tool offers flexible options to encode to Base64 and decode from Base64 for both text and images. All processing happens directly in your browser, ensuring your data remains private and secure.

1. Text to Base64 (Encode Text)

• Input: Type or paste any text into the input box. Our tool supports a wide range of characters, including Unicode.
• Action: Click “Encode Text to Base64.”
• Output: The Base64 string will appear in the output box.

2. Base64 to Text (Decode Text)

• Input: Paste a Base64 string into the input box.
• Action: Click “Decode Base64 to Text.”
• Output: The original readable text will be displayed in the output box.

3. Image to Base64 (Encode Image)

• Input: Click “Upload Image to Encode” and select your JPG, PNG, or WebP file.
• Action: Click “Encode Image to Base64.”
• Output: A Base64 data URL (e.g., data:image/png;base64,...) representing your image will appear in the output box, ready to be copied and used in your code.

4. Base64 to Image (Decode Image)

• Input: Paste a Base64 string (either a full data URL or just the raw Base64 data) into the input box.
• Select Format: If you provide only the raw Base64 data (without data:image/...), select the original image type (JPG, PNG, or WebP) that the Base64 represents.
• Action: Click “Decode Base64 to Image.”
• Output: A preview of the decoded image will appear, along with a download link to save it as a file.
