Which image formats can I convert between?

You can convert any image your browser can open into JPG, PNG, or WEBP.

Does converting to WEBP reduce file size?

Usually yes. WEBP typically produces smaller files than JPG or PNG at a similar visual quality.

Is my image uploaded anywhere?

No. Conversion happens locally in your browser. Your file never leaves your device.
