PNG to JPG
Convert PNG images into JPGs — usually a fraction of the size. Select several files at once and choose how much quality to keep.
- Select one or more PNG files.
- Choose a quality level. 92% is a good default; lower it if you need smaller files.
- Click Convert to JPG. Each file is converted and downloaded in turn.
Why the file gets so much smaller
PNG is lossless: it stores every pixel exactly, which is why screenshots and logos stay perfectly crisp and why photographs saved as PNG are enormous. JPG throws away visual information your eye is bad at noticing. For a photograph that trade is overwhelmingly worthwhile — an 8 MB PNG photo commonly becomes a 600 KB JPG with no visible difference at normal viewing size.
The most common reason to convert is an upload form that rejects PNG, or a file that simply won't fit under a size limit. The second most common is email: several PNG screenshots can easily exceed a 25 MB attachment cap that the same images as JPGs sail under.
Two things you should know before converting
Transparency is lost. JPG has no way to store it, so transparent areas are filled with white. For a logo destined for a white page that is fine; for one going onto a coloured background it will show as an ugly white rectangle. Keep those as PNG.
Text and sharp edges suffer. JPG compression is designed for photographic gradients and handles hard edges badly, producing faint halos around lettering. If your PNG is a screenshot, a diagram, a chart or anything containing text, converting to JPG will visibly degrade it — and because PNG compresses that kind of content well, you often save far less than you would on a photo. Convert screenshots only when you have to, and use the highest quality setting when you do.
The quality slider
92% is the default and is effectively indistinguishable from the original for photographs. Dropping to 80% roughly halves the file again and is still fine for most on-screen use. Below about 70% artefacts become visible in flat areas like skin and sky. Because JPG is lossy, converting a JPG back to PNG later will not recover anything — keep your PNG originals if the images matter.
Converting several at once
Select as many PNGs as you like and each is converted and downloaded in turn. Browsers are cautious about pages that start several downloads in a row, so allow multiple downloads for this site when prompted; batches of about ten are the most reliable. Everything runs in your browser — no upload, no queue, no account, no watermark.
