Understanding Base64 Encoding
What is Base64?
Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format. It's commonly used to:
- Send binary data through email systems
- Embed images in HTML/CSS code
- Store binary data in databases
- Transfer data in URLs
- Encode authentication credentials
Common Use Cases
- Web Development - Embedding images directly in HTML/CSS
- API Development - Sending binary data in JSON payloads
- Email Systems - Encoding attachments
- Data Storage - Storing binary data in text format
Features of Our Tool
- Text Conversion - Encode/decode text strings instantly
- File Support - Convert various file types to Base64
- Bulk Processing - Handle multiple conversions at once
- Data Validation - Verify Base64 string validity

Pro Tip:
Base64 encoding increases the data size by approximately 33% compared to the original binary data. Consider this when working with large files or when storage space is a concern.
