What is Base64 Encoding?
Base64 is an encoding scheme that converts binary data into ASCII text format. It uses 64 characters (A-Z, a-z, 0-9, +, /) to represent binary data, making it safe for transmission over text-based protocols.
Base64 encoding is widely used for:
- Data Transmission: Embedding binary data (images, files) in text formats like JSON, XML, or HTML
- Email Attachments: Encoding binary attachments in email systems
- API Communication: Sending binary data through text-based APIs
- Data Storage: Storing binary data in databases that only accept text
It's important to note that Base64 is encoding, not encryption. It's easily reversible and should not be used for securing sensitive data. The encoded data is about 33% larger than the original binary data, but it ensures safe transmission through systems that only handle text.
Frequently Asked Questions
No. Base64 is an encoding scheme, not encryption. It is easily reversible and should not be used to secure sensitive data.
It is commonly used to embed binary data (like images) into text files (like HTML or JSON) or to ensure data survives transmission without corruption.
