Is transparency preserved?
No. JPG has no transparency, so transparent areas are filled with white.

Why a transparent logo gains a white background as a JPG
This catches people out when a form, marketplace, or print supplier only accepts JPG. The format has no transparency channel at all, so the empty areas have to become some solid colour, and white is the sensible default — it is also what stops those areas turning black, which is the alternative failure everyone remembers. If the transparency matters, WEBP keeps it at a similar file size, and PNG keeps it outright. Convert to JPG when the destination demands it, not as a general-purpose way to shrink a logo.

What this tool does
Convert PNG to JPG turns PNG images into JPG (JPEG) files right in your browser. JPGs are smaller and accepted just about everywhere, which makes this the quick fix when a site, form, or app refuses a PNG. Because JPG has no transparency, any transparent areas are filled with white so nothing turns black or breaks.
How it works
Upload a PNG, set the JPG quality, and the tool decodes the image and re-encodes it as a JPEG on your device. Preview the result and download the new file. Nothing is uploaded.
