About Base64 Encoder/Decoder
What is Base64?
Base64 is an encoding scheme that converts binary data into ASCII text format. It's commonly used to encode binary data (like images or files) for transmission over text-based protocols such as email, URLs, or JSON APIs.
Why Use Base64 Encoding?
Base64 encoding is essential in web development and data transmission:
- •Embed images directly in HTML or CSS (Data URLs)
- •Transmit binary data through text-based APIs
- •Include attachments in email protocols
- •Safely transmit data that might contain special characters
- •Encode/decode instantly without server uploads
How to Use
- Choose between Encode or Decode mode
- Enter your text or upload a file
- Click Encode or Decode to convert
- Copy the result or download the decoded file
Pro Tips
Use Base64 for embedding small images (<10KB) in CSS or HTML to reduce HTTP requests. For larger files, consider using direct file hosting. Base64 increases data size by approximately 33%.
Privacy & Security
All encoding and decoding happens in your browser using native JavaScript APIs. Your files and images never leave your device - everything stays in your browser. No uploads, no servers, ensuring complete privacy and security for your sensitive data.
