Convert PNG to JPG

A photo saved as PNG usually weighs more than it needs to. Drop it below and img-compress re-encodes it as JPG right in your browser — no account, nothing uploaded, and a full folder processes as easily as a single file.

Why convert PNG to JPG?

The most common reason: a photo ended up saved as PNG somewhere along the way — a screenshot of a photo, an export from an app that defaults to PNG — and it's noticeably heavier than it needs to be, since PNG has to work much harder than JPG to compress a photo without losing any detail. Converting to JPG with a reasonable quality setting usually shrinks it dramatically with no visible difference.

One thing to watch for: a transparent PNG background doesn't survive the trip to JPG — it gets filled in with white instead, since JPG has no way to store transparency. For an icon or graphic where that matters, PNG or WebP output would keep it intact; this converter is really built for the oversized-photo case above.

How much smaller, in practice

This is the biggest saving on the site and it isn't close. A photographic PNG converted to JPG routinely drops by 80-90%, because PNG stores photographs pixel by pixel with no lossy compression at all, and photographs are exactly the content lossy compression handles best.

The saving collapses on the wrong content, though. Screenshots, logos, line art and anything containing sharp text are what PNG is genuinely good at, and JPG will both look worse and occasionally weigh more. Flat colour and hard edges mean this is the wrong conversion.

Screenshots are the exception

A screenshot is mostly flat panels, straight rules and text — the pattern lossless compression collapses efficiently and lossy compression mangles. Convert one to JPG and you get soft, smeared halos around every letter, which is the most recognisable JPG artifact there is.

For a screenshot you want to keep the PNG, or convert to WebP, whose lossless mode was designed for precisely this kind of image and still comes out meaningfully smaller than PNG.

What you can't undo afterwards

JPG compression is one-way. Once the file is written, the detail it discarded is gone, and converting the JPG back to PNG later restores nothing — it only wraps the reduced image in a lossless container again at a much larger size.

So keep the PNG original if there's any chance you'll edit the image again. Convert a copy for sending and publishing, and treat the JPG as the output rather than the new master.

FAQ

What quality setting should I pick?

Around 80 is a solid starting point — visually identical to the original at normal size, while cutting file size dramatically. Push it lower only if the file still needs to shrink further and a small, usually invisible, quality trade-off is fine.

Is there ever a reason to keep the PNG instead of converting?

Yes, if the image needs to stay lossless for further editing, or it actually needs transparency. For a plain photo, though, JPG is almost always the better everyday choice.
