About Base64 Encoding
Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format. It is commonly used for:
- Encoding binary data for email transmission
- Storing images inline in JSON or HTML
- API authentication (HTTP Basic Auth headers)
- Data serialization in JSON and XML payloads
Need to encode URL parameters instead? Use the URL Encoder.
Frequently Asked Questions
What is Base64 encoding used for?
Base64 is used to encode binary data for safe transmission in text-based formats like email, JSON payloads, and Basic Auth headers.
Does Base64 encoding encrypt my data?
No. Base64 is encoding, not encryption. Anyone with the Base64 string can decode it back to the original text.
Is my data sent to a server?
No. Encoding and decoding happen entirely in your browser. Your data is never transmitted.
