What is Base64 Decoding?
Base64 decoding is the process of converting a Base64 encoded string back to its original binary or text data. It reverses the encoding process.
When to Use Base64 Decoding?
- Retrieving original data that was embedded in HTML, CSS, or JSON using Base64.

- Extracting binary content from text-based storage like XML or JSON if it was Base64 encoded.
Frequently Asked Questions (FAQ)
What is Base64 encoding?
Base64 is an encoding scheme that converts binary data into text format. It's used for safely transmitting binary data over email or web protocols that only support text.
When should I use Base64?
Use Base64 when embedding images directly in HTML, transmitting binary data through APIs, sending email attachments, or when you need to represent binary data as text.
How does Base64 affect file size?
Base64 encoding increases the size by approximately 33% because it represents every 3 bytes of data with 4 characters.
