About Base64
Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format. It's commonly used for embedding images in CSS/HTML, sending email attachments, and storing complex data in JSON or XML.
Text Encoding
Convert plain text to Base64 for safe transmission in URLs, cookies, or JSON payloads.
File/Image Support
Upload images or files to get Base64-encoded data URLs for embedding directly in your code.
Instant Processing
All encoding/decoding happens in your browser. Fast, private, and no data sent to servers.
Common Use Cases
Embedding Images
Convert small images to Base64 data URLs to reduce HTTP requests. Useful for icons, logos, and inline images.
API Authentication
Basic HTTP authentication uses Base64-encoded credentials in the Authorization header.
Email Attachments
Email protocols use Base64 to encode binary attachments for transmission as text.
Data Storage
Store binary data in JSON, XML, or databases that only support text/string values.
