About this tool
This online PNG to JPG converter draws the source image onto a white canvas and creates a JPEG at your selected quality. JPG can be convenient for photographs and platforms that do not accept PNG, but it does not preserve transparency.
How to use
- Choose the PNG image you want to convert.
- Select the JPG quality level and process the image.
- Download the JPG and check transparent regions, text edges and file size.
Features
- Creates standard JPG output in the browser.
- Provides an adjustable JPEG quality setting.
- Replaces transparent PNG areas with a white background.
Common use cases
- Upload a PNG to a service that accepts JPG only.
- Convert photographic PNG files into a potentially smaller format.
- Create a white-background copy for documents or marketplaces.
Common issues and tips
- JPG cannot store transparency, so transparent pixels become white.
- Low quality settings can create visible artifacts around text and sharp edges.

Frequently asked questions
What happens to PNG transparency?
Transparent and partially transparent regions are composited onto a white background before JPG encoding.
Will JPG always be smaller than PNG?
Not always. It is often smaller for photographs, while logos, text and flat graphics may be better suited to PNG or WebP.
Does conversion change the original file?
No. The tool creates a new JPG download and does not modify the PNG on your device.
