Base64
Base64 is a binary-to-text encoding scheme widely used for embedding images in CSS, transmitting binary data over text protocols, and encoding credentials in HTTP headers. Our Base64 tool lets you encode and decode Base64 strings instantly.
Simply paste your text to encode it into Base64, or paste a Base64 string to decode it back to readable text. The tool supports UTF-8 encoding, making it compatible with international characters and multi-byte text.
Common use cases include encoding data URIs for images, decoding API responses, working with HTTP Basic Authentication headers, and processing email attachments. All operations run locally in your browser with zero data transmission.
Base64 is a method to encode binary data into ASCII text using 64 printable characters. It's commonly used to embed images in web pages, transmit binary data over text protocols, and encode credentials.
Yes. You can encode any text content. For images, the resulting Base64 string can be used as a data URI in HTML or CSS (e.g., data:image/png;base64,...).
No. Base64 is an encoding scheme, not encryption. It makes data portable as text but does not provide any security. Anyone can decode Base64 back to the original data.
