Base64 Decoder

This is an online Base64 decoder tool. Choose the text you want to decode from Base64, paste your Base64 string here, and then you can choose which character to replace the "=" padding with.

This tool helps convert Base64 string/text into an image. After conversion, you can download it as a jpg file.

To convert an image to Base64, you first need to obtain the file contents. This can be done using PHP's file_get_contents() function.

Once the content is fully retrieved, it is encoded in Base64, providing a human-readable text version of any data. This encoding is used when transmitting textual data from a web server or embedding binary files into an HTML page.

Let me explain Base64 encoding and why it matters to you as a DevOps engineer. The reason we use Base64 is actually quite interesting; it essentially comes down to transmitting data over the Internet. When using protocols like HTTP or email, many times the data gets encoded; if the data contains special characters, binary data can get lost or distorted during transmission. To solve this problem, Base64 is used to convert binary data into a simple text string that can be transmitted without loss.
