How to convert PNG to JPG

Four steps, a few seconds, zero uploads.

1

Add your PNG or JPG files

Drag images onto the box above, or click Browse. Drop PNGs to go to JPG, or drop JPGs to go to PNG — the tool detects the direction automatically.

2

Set quality and background

When converting to JPG, choose a quality level (default 92%) and pick a background colour to fill any transparent areas.

3

We convert locally

Latch re-encodes your images using the browser's built-in Canvas API — instantly and offline. Nothing leaves your device.

4

Download your results

Save files one at a time, or grab everything at once in a single zip. That's it.

Frequently asked

Are my images uploaded anywhere?

No. Conversion happens entirely in your browser using the Canvas API. Nothing is sent to a server — the tool works offline too.

What happens to transparent areas when converting PNG to JPG?

JPG doesn't support transparency. You can choose a background colour to fill those areas — white is the default, but you can pick any solid colour using the colour picker.

Can I also convert JPG to PNG?

Yes. Just drop JPG files and the tool automatically switches to JPG → PNG mode. PNG output is lossless, so no quality is lost in the conversion.

What quality setting should I use?

92% is a great default — visually identical to the original with a noticeably smaller file. Use 95–100% for images that will be printed; 70–80% for web thumbnails where file size matters more than sharpness.

Is there a file size or count limit?

You can convert up to 50 images at once, up to 50 MB each. The real constraint is your device's available memory — most image batches are well within those limits.
