Why use a Base64 converter?

Base64 is common in APIs, data URLs, configuration files, and testing payloads. This tool keeps both directions in one place, supports UTF-8 text cleanly, and makes quick copy or download actions easy without switching tabs.

FAQs

Can I encode normal UTF-8 text to Base64?

Yes. The encoder supports regular UTF-8 text instead of limiting conversion to simple ASCII input.

Can I decode Base64 back to text?

Yes. Switch to decode mode and paste the Base64 string to convert it back when the input is valid.

Does this conversion happen in the browser?

Yes. Both encode and decode actions run locally in your browser.

Can I swap the output back into the input?

Yes. The swap action moves the current output into the input field and flips the conversion direction.
