Base64 to Image Converter

Free Base64 to Image Converter

Our online Base64 to Image Converter is a tool that takes a Base64 encoded string, which represents binary data (such as an image file) in a text format, and converts it back into its original binary form, effectively decoding it into an image. Base64 encoding is commonly used for transmitting binary data over text-based protocols such as HTTP or storing binary data in text-based formats like JSON. Our converter extracts the Base64 encoded data from the string and decodes it to reconstruct the original image file. This can be useful, for example, when working with web APIs that return images encoded as Base64 strings or when decoding images embedded in data payloads.

What is Base64?

Base64 is a method used to encode binary data into an ASCII string format using a specific 64-character set. This encoding is designed to make binary data survive transport through transport layers that are not 8-bit clean, such as mail bodies.

Base64 encoding takes every three bytes of binary data (which equates to 24 bits) and converts it into four Base64 characters, each character representing 6 bits of data. This transformation increases the size of the data by approximately 33%, making it slightly larger than the original binary input.

The character set used in standard Base64 encoding includes:

• Uppercase letters A-Z
• Lowercase letters a-z
• Numbers 0-9
• Plus sign (+)
• Slash (/)

In addition, Base64 encoding uses the equals sign (=) as a padding character to ensure that the encoded data has a length that is a multiple of 4.

Base64 is commonly used in many applications including email via MIME, and storing complex data in XML or JSON formats.
