Convert a PNG to a smaller JPG, with a white background where there was transparency.

Turn a PNG into a JPG to drastically cut file size for photos and screenshots. Transparency is flattened against a background colour you choose (white by default).

- **Category:** Image
- **Availability:** Free to use without an account, email address, subscription, or payment.
- **Input:** One visitor-selected file

## How it works

1. Drop in your PNG.
2. Confirm JPG as the output and pick a quality level.
3. Process and download the.jpg file.

## Use cases

- Shrink a heavy PNG screenshot to a small JPG attachment.
- Convert a transparent PNG to a flat JPG for an email signature.
- Prep a PNG for a platform that only accepts JPG uploads.
- Reduce a PNG photo to a phone-friendly file size.

## Frequently asked questions

### What happens to the transparent areas?

JPG has no transparency. Any transparent pixels are flattened against the background colour you pick on the Output tab (white by default).

### Will the JPG be smaller than the PNG?

Almost always yes, often by 5x to 10x for photos and screenshots. JPG uses lossy compression that's a great fit for natural images.

### What quality should I pick?

85 to 90 looks indistinguishable from the source for most images. Drop to 70 if you need maximum compression and don't mind very mild softening.

### Can I keep the original PNG too?

Yes. We don't touch your original; you get a new JPG file. Keep the PNG locally if you need transparency later.
