Base64 Encoder and Decoder Online Tool

What is Base64 Encoding/Decoding?

Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format. It's commonly used to encode binary data that needs to be stored and transferred over media that are designed to deal with text. This encoding helps to ensure that the data remains intact without modification during transport.

Base64 is commonly used in a number of applications including email via MIME, and storing complex data in XML or JSON.

Base64 Encoding/Decoding Tips

• Base64 encoding increases the data size by approximately 33%
• Use Base64 encoding when you need to transmit binary data over text-based protocols
• Be cautious when decoding Base64 strings from untrusted sources, as they may contain malicious data
• Remember that Base64 is not an encryption method and does not provide any security
• When encoding, the result will always be a multiple of 4 characters (padded with '=' if necessary)
