PNG to JPG Converter Online Free

How to convert PNG to JPG

1. Drop in your PNG files.
2. Set the quality slider. 92% is a good default that is visually indistinguishable from the original in most photographs.
3. Convert, then download individually or as a ZIP.

Why this conversion usually saves a lot of space

PNG stores every pixel exactly. For a photograph, that is a poor bargain: photographs are full of subtle gradients and noise that lossless compression cannot reduce much, so PNG photos are often several times larger than they need to be. Screenshots of photographs, images pasted out of documents, and anything saved by a screen-capture tool all tend to arrive as oversized PNGs. Converting to JPG commonly cuts them by 70 to 90%.

What happens to transparency

JPG has no alpha channel, so transparent areas cannot survive the conversion. Rather than leaving them black, which is what naive converters do, this tool fills transparent regions with white before encoding. For a logo on a transparent background, that produces the result you almost certainly wanted. If you need to keep transparency, convert to WebP instead, which supports both lossy compression and an alpha channel.

When to keep the PNG

Line art, screenshots of text, diagrams, and any image with sharp edges between flat colours look worse as JPG. Lossy compression produces faint halos around hard edges, and text is where they show most. For that kind of image, PNG is both smaller and cleaner.

Frequently asked questions

What quality setting should I use?

Between 80% and 92% for photographs. Below about 75% the artefacts become visible in flat areas like skies. Above 95% the file grows quickly for very little gain.

Can I convert back to PNG afterwards?

You can, but it will not restore the detail JPG discarded. Keep the PNG if you may need to edit later.

Is there a file limit?

No fixed limit. Batches are processed one at a time to keep memory use flat.

Are my images uploaded?

No, everything runs locally in your browser.
