Does converting PNG to JPG reduce image quality?

JPG uses lossy compression, so there is some quality trade-off, but at the default quality setting the difference is generally not visible to the eye. You can re-convert at a higher quality if you notice artifacts.

What happens to transparency when converting PNG to JPG?

JPG does not support transparency, so any transparent areas in your PNG file will be filled with a solid white background during conversion.

Is my image uploaded to a server?

No. The conversion from PNG to JPG happens entirely on your device using your browser's built-in image processing — your files are never uploaded anywhere.

PNG and JPG are both common image formats, but they serve different purposes. PNG is typically used for screenshots, while JPG is best known for photographs. Converting from PNG to JPG takes seconds with this tool — just drop your files below, and the conversion happens instantly on your own device.

Screenshots and design exports often arrive as large PNGs — converting to JPG shrinks them dramatically before attaching to an email or uploading to a site with a strict file-size limit.

JPG remains the most universally compatible photo format — converting to JPG is a safe choice when you need a file that will open correctly in absolutely any app, browser, or printer.
