# Convert PNG to JPG.

> PNG to JPG converted in your browser — files stay local.

Convert PNG images to JPG right here **in your browser tab — nothing is uploaded**. Photographic PNGs are often 5–10× smaller as JPG with no visible difference. Transparent regions are flattened onto white, since JPG cannot store transparency. Convert in batches and download the lot as a ZIP.

**No uploads · No ads · Free & open source.**

## How it works

1. Drop files anywhere on the page, click to browse, or paste with Ctrl/⌘ + V.
2. Pick a quality or preset — or set an exact target size and let the tool find it.
3. Compress, compare before/after, and download — individually or as a ZIP.

## Photos yes, screenshots maybe

The big savings apply to photographic content — gradients, textures, real-world scenes — where JPG routinely lands 5–10× smaller. Screenshots with sharp text and flat color panels are JPG’s weak spot: edges halo and small text fuzzes. For those, [PNG to WebP](https://compress-pro.com/png-to-webp) keeps the crispness at a fraction of the size, transparency included.

## Frequently asked questions

### When does PNG to JPG make sense?

For photographic content — photos exported as PNG are needlessly huge, and JPG stores them in a fraction of the size. Screenshots with sharp text and flat colors are usually better kept as PNG.

### What happens to transparency?

JPG cannot store transparency, so transparent pixels are flattened onto a white background. Need transparency? Use the PNG to WebP converter instead.

### Can I control the output size exactly?

Yes — pick a quality, or switch to target-size mode and enter a limit like 200 KB; the tool finds the best quality that fits under it.

### Is it safe for private images?

Yes. The conversion happens entirely on your device — the image is read, re-encoded and saved without ever touching a network. There is no server-side queue, no temporary copy in some bucket, nothing to expire or leak. Want proof? Run one file through, switch your connection off, and run another — it still works.
