Base64 to PDF Decoder
Input: Base64 Encoded PDF
What is Base64?
Base64 is a method of encoding binary data into ASCII characters to facilitate data transfer and storage.
What is Base64 Decoding?
Base64 decoding is the reverse process of Base64 encoding, where binary data is converted back into its original form after being encoded into a human-readable format. The decoding process involves dividing the encoded Base64 string into 6-bit sequences and converting each sequence back into an 8-bit byte using a lookup table. The resulting bytes are then reassembled into the original binary data.
How Does Base64 Decoding Work?
Base64 decoding works by mapping characters from Base64-encoded text back to their binary values. The original binary data is then recreated by combining these binary values. The encoded data is returned to its pre-encoded state after this reverse transformation, ready for processing, storage, or transmission.
Base64 decoding is often used to extract binary data from text-based settings, such as graphics contained in HTML or email communications.
What is a PDF?
PDF is an abbreviation for Portable Document Format. It’s a versatile file format developed by Adobe that enables individuals to exhibit and exchange documents regardless of the software, hardware, or operating systems they’re using. PDF files can contain links, buttons, form fields, audio, video, and business logic.

Base64 Characters
Here is the set of 64 ASCII characters used in Base64 encoding:
- Uppercase and lowercase letters (A-Z, a-z): 26 characters each
- Digits (0-9): 10 characters
- Special characters (“+” and “/”): 2 characters
- Padding character (“=”): Used when the length of binary data is not a multiple of three bytes, ensuring a consistent output format.
