Questions about Base64 Encode / Decode

More answers in the TextVix FAQ.

Is Base64 encryption?

No. Base64 is an encoding that anyone can reverse. Never use it to protect passwords or secrets.

Can I decode a Base64 image?

This tool decodes to text only. If the data isn’t readable text, you’ll see a message instead of garbled output.
