Base64 Encode/Decode

Base64 is a binary-to-text encoding scheme that converts binary data into ASCII characters. It is commonly used to embed images in HTML/CSS, transmit binary data over text-based protocols, and encode credentials in APIs.

Use Base64 when you need to include binary data (like images or files) in text-based formats such as JSON, XML, HTML, or email. It is also used for basic authentication headers and data URIs in web development.

Yes, Base64 encoding increases the data size by approximately 33%. This is a trade-off for the ability to safely transmit binary data through text-only channels without corruption.

Yes, you can encode plain text strings to Base64 and decode Base64 strings back to their original text. The tool supports standard Base64 encoding and decoding operations.

No, Base64 is not encryption. It is an encoding scheme that anyone can easily decode. Never use Base64 to protect sensitive information. For security, use proper encryption methods like AES or RSA.
