FAQ

Is Base64 encryption?

No. Base64 is just an encoding that maps binary data to printable characters — anyone can decode it, so it offers no secrecy. Use real encryption to protect data.

Does my data get uploaded?

No. Encoding, decoding and file reading all happen locally in the browser — your content never leaves your device.

Can I encode images or other files?

Yes. Switch to the File tab and drop any file to get a Base64 Data URI you can paste straight into HTML/CSS.
