How to convert PNG to JPG

A JPG copy is created in a few simple steps.

Choose one or more PNG files, or drag them into the file area.
Pick white, black or a custom color for any transparent areas.
Set the JPG quality and choose the background for transparent pixels.
Convert, compare the preview and download each JPG or a ZIP of all results.

PNG and JPG explained

PNG preserves transparency and sharp graphic edges, while JPG is compact and supported by almost every site, app and device.

PNG image: PNG
JPG image: JPG

Transparent pixels must be filled because JPG has no transparency channel.
JPG uses lossy compression, so repeated saving can gradually soften fine details.

When JPG is the better choice

Convert when the receiving service requires JPG. A smaller file is possible, but is not guaranteed.

Uploading a PNG photo to a service that accepts only JPG or JPEG.
Trying a JPG copy of a photographic PNG, then checking whether its actual size is smaller.
Preparing images for email, forms, social posts or older software.

Choose a sensible JPG quality

For a photograph, try 80–90 as a starting point and compare the actual bytes and detail. The same setting behaves differently on text or flat artwork.

Keep PNG for screenshots, text or diagrams unless the destination requires JPG. In our synthetic text-and-lines test, JPG quality 82 was 8.7 times the PNG size; this is one measured sample, not a prediction for your file.
Check edges around text and high-contrast details in the preview before downloading.

Your PNG stays on your device

Conversion runs locally in your browser and the selected files are not uploaded.

Files disappear from the tool when you clear the list or close the tab.
File names and image contents are never included in analytics events.

FAQ

Frequently asked questions

What happens to transparent PNG areas?

They are filled with the background color you choose before the JPG is created.

Can I convert several PNG files at once?

Yes. Process multiple PNG files and download the results individually or together as a ZIP.

Will PNG to JPG reduce quality?

JPG is lossy. Even a larger JPG can change fine text and edges. Compare a copy at the intended display size and keep the original.

Is JPG always smaller than PNG?

No. Flat colours and repeated text can be more compact in PNG. Check the measured PNG/JPG guide linked on this page, then compare one of your own files before converting a batch.
