The Base64 Encoder/Decoder handles both directions effortlessly. To encode, paste your text into the input field or upload a file — the Base64 output appears instantly. For decoding, paste a Base64 string and click Decode to see the original content. The tool auto-detects whether you're encoding or decoding based on your input. For images, it generates complete data URIs you can copy directly into HTML or CSS. Batch mode lets you process multiple strings at once, one per line. All processing is done locally in your browser for maximum speed and privacy.
Base64 is a binary-to-text encoding scheme that converts binary data into ASCII characters, commonly used for embedding data in web pages and APIs.
Yes, upload any file and the tool converts it to a Base64 string. This works for images, documents, and any binary file.
No, Base64 is encoding, not encryption. It's easily reversible and should not be used for security purposes. Use proper encryption for sensitive data.
Encoding converts plain text or binary to Base64 format. Decoding converts Base64 back to the original text or binary data.
Yes, the tool can generate data URI strings with the proper MIME type prefix, ready to use in HTML img tags or CSS.
