Base64 Previewer Tool

What is Base64 Encoding?

Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format. It's commonly used to encode data that needs to be stored and transferred over media designed to deal with textual data. This ensures that the data remains intact without modification during transport.

Step-by-Step Guide to Using This Tool

1. Encoding Text to Base64: Select "Text" as input type, type or paste your text in the input field, and click "Encode to Base64". The Base64 result will appear instantly.
2. Decoding Base64 to Text: Select "Base64" as input type, paste your Base64 string, and click "Decode from Base64". The decoded content will appear in the preview area.
3. Encoding Files: Use the file upload button to select any file (image, PDF, document). The tool will automatically convert it to Base64.
4. Previewing Content: Switch between Text, Image, and Hex preview modes to view your decoded content in different formats.
5. Copying Results: Use the "Copy Base64" or "Copy Decoded Text" buttons to quickly copy results to your clipboard.
6. Validating Base64: Click "Validate Base64" to check if your string is properly formatted Base64 data.

Common Use Cases

• Embedding images directly in HTML or CSS using data URLs
