PNG to JPG

How to convert PNG to JPG

1. Drop your .png files onto the box above, click it to browse, or paste a screenshot straight from the clipboard.
2. Set the JPG quality. 85 is a sensible starting point for photos and most screenshots, and the line under the slider tells you what to expect as you move it.
3. Check the background colour. If any image has transparent areas, the page points them out as soon as the files are added, and those areas will be filled with the colour shown, which is white until you change it.
4. Press Convert to JPG. Each PNG becomes a .jpg of the same name, several are delivered together in one ZIP, and the status line shows the total size before and after.

What people use it for

PNG is what screenshots, screen captures on a phone and many exported images default to, and it is a heavy choice for anything photographic, because PNG never throws detail away. Converting to JPG is the quickest way to bring such files down to a size that travels easily.

• Fitting a batch of screenshots into an email or a support ticket that has an attachment limit.
• Uploading a photo that was saved as PNG to a form that caps the file size or accepts JPG only.
• Slimming images before they go into a slide deck or a word-processor document, so the document itself stays manageable.
• Cutting down the pictures for a blog post or a shop page so it loads faster.
• Clearing space on a phone or a shared drive that has filled up with screen captures nobody needs pixel-perfect.

Good to know

Two things are given up along the way. The first is transparency: JPG has no see-through pixels, so transparent areas are filled with the colour you choose, and a logo meant to sit on a coloured page may need that colour rather than white. The second is perfectly sharp edges. JPG compression suits photographs but can leave faint halos around small text and thin lines, especially at lower quality, so screenshots full of writing are best kept at 85 or above. Simple graphics with a handful of flat colours can even come out larger as a JPG; the status line points such files out, and they are better left as PNG. If you only want smaller files and the format does not matter, Compress Image works on JPG and WebP too.

None of your pictures leave the computer or phone you are holding. The conversion happens inside this open page, using the browser's own image decoder and JPG encoder, so screenshots showing personal details, account pages or private conversations are never handed to anybody else.

Questions people ask

What sort of saving can I expect?

That depends on what is in them. Photographs saved as PNG usually shrink a great deal, while screenshots with large areas of plain colour shrink less. The page adds up the sizes before and after, so you see the real saving for your own files rather than an estimate.

Why do the transparent parts turn white?

JPG cannot store transparency, so every transparent pixel needs a solid colour instead. White is the default, and you can pick any other colour before converting. To keep the transparency itself, the image has to stay a PNG.

Which quality setting should I choose?

For screenshots with text, 85 to 95 keeps the writing clean. Photographs look fine from about 75 upwards. Below that the files get smaller still, but blocky patches and blurred edges begin to show.

Can I convert WebP or JPG files here as well?

This page accepts PNG only. WebP images have their own converter in WebP to JPG, and a JPG that is simply too big is better served by Compress Image. For other combinations, use Convert Image.
