PNG to JPG Converter

Turn large PNGs into compact JPGs for email, uploads, and sharing. Transparent areas are filled with white by default — or any colour you pick — so you never get surprise black backgrounds.

How to use the PNG to JPG converter

  1. Step 1

    Add PNG files

    Screenshots, graphics, or photos saved as PNG — add one or many.

  2. Step 2

    Pick a background and quality

    Transparent areas become the colour you choose. The preview updates instantly.

  3. Step 3

    Download your JPGs

    See the new size of each file, then download individually or as a ZIP.

What happens to transparency

JPG has no transparency channel, so every transparent or semi-transparent pixel has to be blended onto a solid colour. Some converters silently use black. Here the background is white unless you choose otherwise, and the preview shows the exact blend — including soft anti-aliased edges — before you convert.

If you need to keep the transparent background, stay with PNG (or use WebP for the web).

Choosing a quality

For photos saved as PNG, JPG at 85–92% is often dramatically smaller with no visible difference. For screenshots with sharp text, use a higher quality (90%+) — JPEG can show faint halos around high-contrast edges at low quality.

Questions about PNG to JPG

Are my files uploaded to a server?

No. This tool runs entirely in your browser: your files are read and converted on your own device and are never sent to ZuffSuite. The page downloads the conversion code it needs, then works on the files locally. Closing or reloading the tab discards everything.

Why do some PNG to JPG converters give a black background?

Transparent pixels have no colour of their own; when a converter writes them to JPG without choosing a fill, they often become black. This tool fills them with white by default, or any colour you choose.

Will converting PNG to JPG reduce quality?

JPG is lossy, so it does discard some detail. At the default 90% quality the difference is very hard to see for photos; sharp text and line art are better kept as PNG.

Can I convert many PNG files at once?

Yes. Add a batch, choose one background and quality for all of them, and download them as a ZIP.
