What is Base64 encoding?

Base64 encoding converts binary data like images into ASCII text that can be embedded directly in HTML, CSS, or JSON without a separate file.

Is my image uploaded to a server?

No. All encoding and decoding happens in your browser using the FileReader API. Your images never leave your device.

What image formats are supported?

Any format your browser supports — PNG, JPEG, WebP, GIF, SVG, and more.
