Free PNG to JPG Converter

This free tool converts PNG images to JPG in your browser. It is the right call when a PNG photograph has become absurdly large, and the wrong one if the image has a transparent background, which JPG cannot keep.

PNG files — add as many as you like

Runs entirely in your browser. Your images are never uploaded to a server.

How it works

  1. Drop the PNG above, or a folder of them.
  2. Set a quality. Around 80 is the usual sweet spot for a photograph: below 60 you start to see it, above 90 the file grows for very little gain.
  3. Download the JPG. If the PNG had transparency, those areas arrive as solid white.

Common use cases

Frequently asked questions

What happens to a transparent background?
It becomes solid white. JPG has no alpha channel at all, so every transparent pixel has to be filled with something, and white is the convention. This is the one thing to check before converting: a logo that sat cleanly on any background will arrive on a white rectangle, and there is no way to undo it afterwards short of removing the background again. If you need transparency, convert to WebP instead, which keeps it and is smaller than the PNG anyway.
How much smaller will the JPG be?
For a photograph, dramatically: five to ten times smaller is ordinary, because PNG stores every pixel exactly and a photograph gives its compression almost nothing to work with. For a flat graphic, logo or screenshot, much less, and sometimes the JPG is actually larger. PNG is very good at large areas of identical color, which is exactly what a screenshot is made of, and JPG is bad at the hard edges around text.
Will the quality drop?
Yes, because JPG is lossy. On a photograph at quality 80 or above the difference is genuinely hard to see, and the file saving is enormous, which is why this trade is usually worth making. On text, line art and screenshots it is a different story: JPG smears faintly around hard edges, and a screenshot converted to JPG looks slightly grubby in a way that is hard to unsee once noticed.
Should this be a WebP instead?
Probably, if it is going on a website. WebP is smaller than JPG at the same quality, keeps transparency if there is any, and every current browser reads it. JPG remains the right answer for email, print, marketplace uploads and anywhere the file has to open in software you do not control.
Is there a way to shrink a PNG without leaving PNG?
Yes. Our PNG compressor reduces how many distinct colors the file stores, which on graphics and screenshots often halves the size with no visible change and no format change. That is the better route when the image has transparency or sharp text, both of which JPG handles badly.
Where does the conversion happen?
In your browser, using the Canvas API. Nothing is uploaded and nothing is stored.
