Popular Base64 Tools


Base64 Encoder

Base64 Encoder is a tool for converting binary data into a text format that can be securely transmitted over a transmission mechanism that does not properly support binary data.


Base64 Decoder

Base64 Decoder is a program that decodes Base64 text and converts it back to its original form. This is handy for debugging, testing, or simply examining the original Base64-encoded data.


Image to Base64

Image to Base64 is a process of converting an image file into a Base64 encoded string. This can be useful for storing images in a text format.


Base64 to Image

This tool allows you to convert Base64 encoded data into images. This is ideal for those who need to restore images from Base64 encoding.

And Even More Tools

We provide a range of tools for Base64, Base32, and other variants to assist with encoding, decoding, and conversion. Our tools are user-friendly, free, and readily available for use.


What is Base64?

Base64 is a binary-to-text encoding scheme that represents binary data in a textual format. It is often used to transmit binary data over protocols that only support text, such as HTTP.

How does Base64 work?

Base64 works by dividing binary data into 6 bit groups. Each group of six bits is then converted into a character from a subset of 64 characters that are safe to send over text-based protocols.

Where is Base64 used?

Base64 is used in a wide range of applications, including:

  • Encoding binary data in an ASCII string format
  • Transporting binary-formatted data across channels that can only reliably support text content
  • Embedding image files or other binary assets on the World Wide Web within textual assets such as HTML and CSS files
  • Sending e-mail attachments, because SMTP was originally designed to transport only 7-bit ASCII characters.
  • Using the data URI scheme to represent file contents, for example, background images and fonts can be specified as data: URIs in a CSS stylesheet file instead of being supplied in separate files.
