What is Base64 encoding used for?

Base64 encoding is used to convert binary data (like images or files) into a text format that can be safely transmitted over text-based protocols like HTTP, email, or stored in JSON.

Can I convert files to Base64?

Yes, you can drag and drop or upload a file to convert it to a Base64 string, including generating a data URL for direct use in HTML or CSS.

Is the conversion done server-side?

No, all encoding and decoding happens locally in your browser. Your data is never uploaded to any server.

Does Base64 make my data larger?

Yes, Base64 inflates data by about 33 percent. It is for transport compatibility, not compression.
