The world of coding is a complicated one, especially if you are looking from the outside. You may have encountered Base64 encoding and wondered what that term means. Suppose you want to ship binary data across a network. It would be wise to refrain from streaming the bits and bytes in their raw format.
The best thing to do would be to encode the data into a Base64 format. Encoding also prevents your binary data from being damaged. Stick around to learn four efficient methods to convert your PDF to Base64.
In this article
What Is Base64?
Base64 is an encoding scheme representing a sequence of 8-bit bytes in sequences of 24 bits. These bits are then classified into four 6-but digits in the Base64 format. Base64 is commonly used in the World Wide Web and helps developers embed binary assets and other image files into textual assets.
Another everyday use for Base64 is sending email attachments. Simple Mail Transfer Protocol was initially designed to transport 7-bit ASCII characters. Unfortunately, this encoding system led to a high percentage of overhead due to inserted line breaks. Base64 has proven to be a more reliable way to send email attachments.
The moment you have a good grasp on Base4, you can apply it to OpenSSL, Kubernetes secrets, and email applications. You can also be in a better position to understand how data is stored in the tools you use every day.
Why Use Base64?
Some various mediums and protocols cannot handle data in the binary format. Base64 converts binary data into printable text that is simple to read and recognizable to these mediums.
Where ASCII uses 8 bits to represent individual characters, Base64 uses six. The 8-bit chunks are too large for some mediums to handle, making it necessary to break them down into 6-bit chunks, which are smaller. You can use an ASCII-to-binary conversion table to look up the values of each character. The final step would be to use a Base64 table to convert the 6-bit values to simple text.
Method 1. PDF to Base64 Converter Software
Developers have been working round the clock to design software to help users like you convert pdf to Base64 online. There are so many options in the market that you can barely exhaust them all. The first efficient software converter you can use is Base64 Encoder.
Base64 Encoder was released six (6) years ago and is a product of Sourceforge, which was founded in 1999 to be a complete software platform for business and open-source software. It can encode any file you want, including .txt and .exe files, meaning you don't have to worry about the software not recognizing the file you want to convert. Here are some other excellent features that come with this software.
- A lowered net dependency to 2.0

Method 3. Convert PDF to Base63 String in Python
Python is a high-level programming language characterized by dynamic semantics, exceptions, modules, and dynamic typing. One striking fact about Python is that it combines syntax with incredible power. Python also interfaces with many windows systems, libraries, and system calls. Last but not least, Python is extensible to both C and C++ programming languages.
Here is a list of code you can use with Python 3 to convert PDF to Base64 string.
Step 1 The following is a list of codes you could use to import the PDF file you want to convert.
Step 2 This is what the output should look like.
Step 3 Save the Base64 file in the desired output folder on your device, as shown.
Method 4. Use Java To Convert PDF to Base64
James Gosling designed Java in 1995 as a programming language mainly for coding web applications. Over the years, Java has grown in popularity, and most developers prefer to use it over other programming languages in the market.
You can use Java in the Internet of things, cloud computing, developing games, artificial intelligence, data processing engines, and server-side technologies. Since Java is a network-centric, object-oriented language, you can use the platform the way it is,
This section of the article will show you how to use Java to convert your PDF to Base64 file format.
Step 1 Pass the PDF through java.util.Base64.Encoder to transform the digital document into bytes. Here is the code to help you achieve that.
Step 2 If you have limited memory and are converting large files, you can perform the encoding method using a stream, as shown below.
