Frequently Asked Questions

What happens to transparent backgrounds when converting PNG to JPG?

Because the JPEG format specification does not support alpha channel transparency, transparent PNG pixels are automatically rendered against a solid white background (or custom matte color) during canvas rasterization.

How much smaller will my JPG file be compared to the original PNG?

Photographic images converted from PNG to JPG typically see size reductions of 60% to 85%, depending on the quality slider setting. Graphic illustrations with flat colors may not shrink as significantly.

Are my photos uploaded to a cloud server during conversion?

No. The conversion pipeline executes entirely within your browser utilizing the HTML5 Canvas API and WebAssembly codecs. Your image data never leaves your computer or phone.
