Convert Base64 encoded data back to original format

Understanding Base64

Base64 is an encoding method that converts binary data into ASCII text. It is widely used when binary data needs to be stored or transmitted as text. Decoding reverses this, revealing the original content.

Where You See Base64

Email Attachments: Files are Base64 encoded for transmission
Data URIs: Images embedded directly in HTML or CSS
API Responses: Binary data returned as text
Authentication: Basic auth headers use Base64

What This Tool Does

Paste any Base64 encoded string and see the decoded output. The tool handles both text content and can identify binary data.

Recognizing Base64

Base64 strings contain only letters (A-Z, a-z), numbers (0-9), plus (+), slash (/), and may end with equals signs (=) for padding.
