Are my files uploaded to a server?

No. The conversion runs entirely in your browser using your device — your files never leave your computer and are never uploaded to us or anyone else.

Why is my JPG smaller than the PNG?

JPG uses lossy compression tuned for photos, which is usually far more efficient than PNG for photographic content.

What happens to transparent pixels?

They are filled with white, because the JPG format cannot store transparency.

Why convert PNG to JPG?

PNG is lossless and great for graphics, but photos saved as PNG are often very large. JPG produces much smaller files for photographic images, ideal for sharing and faster web pages.

What happens to transparency?

JPG does not support transparency. Any transparent areas in your PNG are placed on a white background when converting to JPG.
