Base64 encoder - encode base64 online
Encode your data effectively using the A2Z base64 encoder online
A2Z Base64 Encoder Online is a simple and secure online tool that quickly and easily decodes from Base64 encoding as well as encodes into it. Your data can be easily encoded using Base64 or decoded into a format that is readable by humans.
When it comes to encoding binary data, Base64 encoding schemes are often used, especially when the data needs to be saved and transported through mediums that is intended to handle text. This encoding helps in ensuring that the data is transported without being altered. Base64 is frequently used in a variety of applications, such as email via MIME and the storage of complex data in XML or JSON.
What Is Base64 Encoding?
Base64 encoding converts binary or text data into a printable ASCII string format. It is required to safely carry binary data via a transmission protocol/medium that does not support or correctly handle binary data.
Base64 is not an encryption or compression method. It is an encoding system that converts binary data such as images or files to the ASCII character set.
Base64 has its name because it works with a subset of 64 ASCII characters. Upper and lowercase alphabets (A-Za-z), numerals (0-9), +, and / are among the characters.
Why is Base64 Encoding used?
Base64 encoding is a method of converting binary data into the ASCII character set. Encoding is required to reliably send binary data via communication media/protocols that are only designed to handle textual data.
For instance, textual data of ASCII character sets were usually supported by email servers. If you want to transfer photos or other files via email, you must first encode the image or file to Base64 encoded format and then send the encoded data to the email server.
The encoded data can be transformed back to the original image or file at the receiver's end using Base64 decoding. Base64 decoding is the inverse process of encoding. It converts Base64 encoded data back to binary data.
It should be noted that Base64 is not to be confused with encryption or compression algorithms. It's simply an encoding algorithm. Base64 encoding should not be used to hide sensitive data.
How does the Base64 encoding algorithm work?
Encoding in Base64 is a multi-step procedure. But it's quite simple. This is how it works:
1. Change the input to 8-bit bytes.
2. Reorganize the input into 6-bit groups.
3. Determine the decimal equivalent of each 6-bit group.
4. Find the character corresponding to the decimal values using the Base64 alphabet table.
5. If the input cannot be divided into an integer number of 6-bit groups, one or two pad characters are added to the output depending on the following conditions:
If the last group has 2 bits, add four zero bits to the input.
If the last group has 4 bits, add two zero bits to the input.
The first case adds two pad characters (=) to the Base64 output, while the second adds a single pad character (=).
About A2Z Base64Encoder online:
A2Z Base64Encoder is a simple and user-friendly web application for converting any binary or text data to Base64 encoded format.
Start by typing or pasting any string into the input text section; the program will convert the data in real-time to Base64 encoded format. Once the data has been encoded, you can copy it by clicking in the output text area.
The same program can also function as a Base64 decoder.
Base 64Decoder is another basic and easy-to-use web tool for decoding any Base64 encoded data back to binary data.
Start by entering or pasting any Base64-encoded data into the input text section; the program will instantly decode your input. Clicking in the output text section will allow you to copy the decoded data once the input has been decoded.
