Paste or type your text into the input field and select "Encode". The Base64-encoded output will appear instantly. You can also drag and drop files to encode their contents.
Paste the Base64-encoded string into the input field and select "Decode". The tool will automatically detect if the input is Base64 and decode it to its original text representation.
No. Base64 is an encoding scheme, not encryption. It transforms binary data into ASCII text for safe transport but provides no security. Anyone can decode a Base64 string. For security, use proper encryption algorithms.
Base64 is commonly used to embed images in HTML/CSS, encode email attachments (MIME), transmit binary data in JSON/XML APIs, and store binary data in text-based formats like configuration files.
