What is Base64 Encoding?


Base64 is a binary-to-text encoding scheme that represents binary data using 64 printable ASCII characters. It's commonly used to encode data that needs to be stored or transferred over media designed to handle text.


How Base64 Works


Base64 encoding takes groups of 3 bytes (24 bits) and converts them into 4 ASCII characters. Each character represents 6 bits of data from the original input, using an alphabet of A-Z, a-z, 0-9, and two additional characters (+ and /).


Common Use Cases


    

  • APIs & Web Services: Encode binary data for JSON/XML transmission
    • 

  • Email Attachments: MIME encoding for email content
    • 

  • Data URLs: Embed images and files directly in HTML/CSS
    • 

  • Authentication: HTTP Basic Authentication headers
    • 

  • Cookies & Tokens: Store complex data in URL-safe format
    • 

  • Configuration: Encode credentials or secrets in config files
    • 



Privacy & Security


This tool runs entirely in your browser using JavaScript. Your text is never sent to any server—all encoding happens locally on your device. Note: Base64 is encoding, not encryption—it should not be used for security purposes.


Technical Details


    

  • Output is approximately 33% larger than input
    • 

  • Padding with '=' characters ensures proper decoding
    • 

  • URL-safe Base64 replaces + with - and / with _
    • 

  • Fully supports UTF-8 text and special characters
    •

                        Yes! All encoding happens locally in your browser using JavaScript. Your text never leaves your device and is not sent to any server.
                    

                

            

                    

                
                

                    

                        Base64 is commonly used for encoding binary data in APIs, email attachments (MIME), data URLs, authentication headers, and storing complex data in URLs or configuration files.
                    

                

            

                    

                
                

                    

                        Yes! This tool properly handles UTF-8 text including special characters, emojis, and non-Latin scripts by using TextEncoder for proper byte conversion.
                    

                

            

                    

                
                

                    

                        No! Base64 is encoding, not encryption. It transforms data into a different format but does not provide any security. Anyone can decode Base64 data, so it should not be used for protecting sensitive information.
