About Base64 encoding
What is Base64?
Base64 is a binary-to-text encoding scheme that represents binary data in ASCII format. It's commonly used for encoding data in email, data URIs, and web applications.
Common Use Cases:
- • Embedding images in HTML/CSS (data URIs)
- • Email attachments (MIME encoding)
- • API data transmission
- • Storing binary data in text formats
Features:
- • Text and file encoding/decoding
- • Image preview for uploaded files
- • URL-safe encoding support
- • Copy to clipboard functionality
- • File download capability
- • No server upload required
Note: All encoding/decoding happens in your browser. Files are not uploaded to any server.
