THREE SMALL STEPS

How to png to jpg converter.

  1. Choose your PNG image.
  2. JPG output is selected. Adjust quality and dimensions if needed.
  3. Download the encoded JPG file and compare its reported size.

A white background for transparent areas.

PNG can hold transparent pixels, while JPG cannot. This page selects JPG output and fills transparent areas with white. Use it when a service expects a photographic JPG or when a white-backed version of a graphic is appropriate.

Choose a quality level that keeps thin edges and small lettering readable. JPG is a lossy format, so a logo or screenshot may show ringing around sharp shapes. Converting a flat graphic is not guaranteed to make it smaller than its PNG original.

The output is a newly encoded JPG, rather than a renamed PNG. Colour changes and layers already in the editor are included in the export. Keep the original transparent PNG if you may need a different background later.

A FEW USEFUL DETAILS

Before you download.

What happens to transparency? +

Transparent pixels become white because JPG has no alpha channel. Choose PNG or WebP when transparency needs to remain.

Will JPG always be smaller? +

No. Dimensions, image detail and quality affect the size. The download message reports the actual file size.

Can I get the transparent PNG back from the JPG? +

The new JPG has flattened those pixels. Keep your original PNG for a transparent version.
