FAQ
What is the difference between URL encoding and Base64?
URL encoding converts characters into %xx form to make them safe inside URLs. Base64 converts binary data into ASCII strings. They solve different problems.
Is Base64 encryption?
No. Base64 is reversible encoding. If you need secrecy, use encryption.
Is my data sent to a server?
No. Everything runs locally in your browser and nothing is uploaded.
