Convert Base64 to Image

How to Use Base64 to Image Converter?

To use this converter, you will paste the base64 string and click on the convert to image button. You will get the image below the text filed. The Base64 contains all the 26 alphabets both in uppercase and lowercase.  Currently the tool supports only the conversion of Base64 string and decoding it into image. In future we will add the functionality to download the image with uploading of the text file, and fetching base64 string from the URL.

This tool works on any operating system Windows, MacOS, Linux and any browser.

More Concepts for your understanding

Base64 Encoding

  • Base64 is an encoding scheme that is used to represent binary data in a text format. It takes binary data and converts it into a series of ASCII characters using a set of 64 characters (hence the name Base64).
  • This encoding is commonly used for encoding data that needs to be transmitted over text-based protocols, such as when embedding images in HTML, CSS, or when sending binary data over email.

Image Data

Images are typically stored in binary formats, such as JPEG, PNG, GIF, etc. These formats are not text-based and consist of binary data that represents pixel information, metadata, and other image-related details.

Using Base64 with Images

Base64 encoding is often used to embed images directly into HTML, CSS, or other text-based formats. Instead of linking to an external image file, the image data itself is encoded in Base64 and included directly in the document. This can be useful in certain situations, such as reducing the number of server requests or when the image is relatively small.

Pros and Cons

  • Pros: Base64-encoded images can be easily included in text-based files, reducing the need for additional HTTP requests. This can be advantageous for small images or when performance considerations dictate such an approach.
  • Cons: Base64 encoding increases the size of the data by about one-third, as each 8 bits of original binary data turn into 6 bits of Base64-encoded data. This can lead to larger file sizes, and for large images, it might be less efficient than linking to an external image file.
