Why convert JPG to PNG?

PNG uses lossless compression, so converting from JPG to PNG preserves the current quality without further degradation. PNG also supports transparency.

Will converting JPG to PNG increase file size?

Yes, PNG files are typically larger than JPG because PNG uses lossless compression. However, the image quality is preserved without any further loss.

Can I add transparency after converting?

The conversion creates a PNG file which supports transparency, but the original JPG content will have an opaque background. You would need an image editor to add transparency.

Is my image uploaded anywhere?

No, the conversion happens entirely in your browser using the Canvas API. Your images stay on your device.
