What is Base64?
+
It's a way to represent binary data using only readable text (letters, numbers, and a few symbols), useful when a system only accepts plain text.
Is Base64 a form of encryption?
+
No. Base64 doesn't hide or protect anything — anyone can decode it easily. It's just encoding, not encryption. If you need to actually protect a file, use our "Encrypt file" tool.
Is my text sent to any server?

No. Encoding and decoding happen completely in your browser.
