Base64 encoding is a binary-to-text encoding scheme that represents binary data in an ASCII string format. It's commonly used for encoding data in JSON, XML, email attachments, and embedding images in HTML/CSS. Our Base64 encoder decoder provides instant encoding and decoding with no file size limits. For hashing text, try our Hash Generator.

Key Features:

  • Encode text to Base64 - Convert any text string to Base64 format
  • Decode Base64 to text - Convert Base64 strings back to original text
  • Instant processing - Fast encoding and decoding in real-time
  • No size limits - Process text of any length
  • Completely free - No registration, no limits

How to Use Base64 Encoder Decoder

Frequently Asked Questions

Is the Base64 encoder decoder free to use?

Yes, our Base64 encoder decoder is completely free to use. No registration or payment required.

What is Base64 encoding used for?

Base64 encoding is commonly used to encode binary data (like images) into text format for transmission over text-based protocols, embedding in HTML/CSS, or storing in JSON/XML.

Can I encode images to Base64?

This tool encodes text to Base64. For encoding images to Base64, you would need to first convert the image to its binary representation, then encode that binary data.
