Base64 Encoder/Decoder

What is a Base64 Encoder/Decoder?

A Base64 Encoder/Decoder is a versatile data conversion tool that both encodes text and files into Base64 format and decodes Base64 strings back to their original form. This bidirectional tool helps developers, system administrators, and technical professionals handle data encoding for APIs, email attachments, data URIs, authentication tokens, and various web applications. Whether you need to encode binary data for text transmission or decode Base64 strings to retrieve original content, this tool provides both functions in one convenient interface. Our converter tools include related encoding utilities like Base64 encoders to support your data conversion needs.

How to Use Base64 Encoder/Decoder?

Encoding and decoding Base64 is simple:

1. Choose Input Type: Select whether you want to encode/decode text or upload a file for encoding.
2. Select Mode: Choose encode mode to convert text/files to Base64, or decode mode to convert Base64 back to original format.
3. Enter or Upload Data: Paste your text, upload a file, or paste a Base64 string depending on your operation.
4. Process & Copy: Click encode or decode to process your data, then copy the result or download it as needed.

This tool is essential for developers working with web APIs, data transmission, email systems, and applications where Base64 encoding is required for safe data handling and transmission across different systems and protocols.
