Free Base64 Decoder Online - Decode Base64 String to Image, PDF, Text

What is Base64 Encoding and Why Use a Base64 Decoder?

Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format. It's commonly used to embed binary data (like images, PDFs, or files) directly into text-based formats such as HTML, CSS, JSON, or XML, especially when dealing with data that needs to be transmitted over mediums that only reliably support text. Our base64 decoder online free tool helps you decode these base64 strings back to their original format instantly, whether you need todecode base64 string to image, convert base64 to PDF, or extract text from base64 encoded data.

Example Base64 Encoded Image:
