Why Convert PNG to JPG?
The number one reason is size. A PNG screenshot, export, or design file can weigh several megabytes, and that's a problem when you need to email it, attach it within a size limit, or load it quickly on a web page. The same image as a JPG is often 5 to 20 times smaller, so converting PNG to JPG is the fastest way to make a heavy file manageable.
The second reason is compatibility. Some upload forms, older systems, photo kiosks, and document workflows only accept JPG. Turning your PNG into a JPG gets it through whatever gate is rejecting it, without any loss you can see at sensible quality.
In short: PNG keeps every pixel; JPG keeps your upload under the size limit. This tool does the conversion in seconds, in your browser, and shows you exactly how much smaller each file became.
PNG vs JPG: What's the Difference?
PNG is a lossless format with transparency support — perfect for graphics and screenshots, but large. JPG is a lossy, compressed format with no transparency — much smaller, ideal for photos and anywhere file size matters.
PNG never throws pixels away and can store a transparent background, which makes it ideal for logos, icons, and crisp screenshots — but those qualities also make it big.
JPG uses lossy compression to shrink files dramatically, at the cost of transparency and a tiny amount of detail. When you convert PNG to JPG you trade those away for a far smaller, universally accepted file — the right move whenever size or compatibility matters more than transparency.
How to Convert PNG to JPG in 3 Steps
There's nothing to install and no account to create. Here's how to convert PNG to JPG from any device with a modern browser.
Add your PNG files
Drag your images — or a whole folder — onto the box above, or click to browse. Everything stays on your device; nothing is uploaded to a server.
Set quality & background
Pick a JPG quality (90 is visually identical) and choose the color that fills any transparent areas — white by default, or black or a custom color.
Convert and download
Each file is encoded right in your browser. Download them individually or as a ZIP, and see exactly how much smaller each one became.
Pro tip: Need to keep transparency? Don't convert to JPG — keep the PNG, or work with a transparency-friendly format like our WebP to PNG tool.
What Happens to a Transparent Background?
This is the question almost every PNG to JPG converter ignores — and the one that surprises the most people. JPG has no alpha channel, which means it cannot store transparency at all. Every transparent pixel in your PNG has to be filled with a solid color when it becomes a JPG.
Many tools fill those areas with black without warning you, so a logo on a transparent background suddenly has an ugly dark box behind it. This converter defaults to white — what most people expect for documents, prints, and forms — and lets you pick black or any custom color right in the main panel, with no settings hidden away.
If keeping the transparency is essential, JPG is simply the wrong format. In that case, keep your PNG. Convert PNG to JPG only when a solid background is acceptable.
How Much Smaller Will the JPG Be?
JPG's lossy compression usually cuts a PNG down to a fraction of its size. Screenshots and flat graphics shrink the most — it's common to see a multi-megabyte PNG become a few hundred kilobytes as a JPG. Rather than guessing, this tool shows each file's original size, the new size, and the percentage saved, so you can see the win.
The quality slider controls the trade-off. At 90, the JPG looks identical to the original for almost any image; drop it to 75 or 80 when you need an even smaller file and a little softening is acceptable. Converting at the right quality is how you slip under an upload limit without an obvious loss.
PNG to JPG on Windows, Mac & in Bulk
The same browser tool works everywhere. Here's what it handles in each case.
On Windows 10 & 11
No software to install — the browser handles PNG to JPG on Windows directly, so you can shrink a screenshot or export in seconds.
On Mac
Preview converts one file at a time. Drop a whole folder here instead for a batch, and download every JPG in one ZIP.
In bulk
Add hundreds of PNGs at once — there's no server, so there's no batch cap, and a single ZIP brings them all down together.
Your Images Never Leave Your Device
Every other PNG to JPG converter in the top results uploads your files to a server. This tool doesn't: your images are converted by your own browser's canvas, so nothing is ever transmitted — handy when the PNG is a private screenshot, a document, or a design you'd rather not send anywhere.
Because nothing is uploaded, there's no size cap, no queue, and no account to create — and the tool keeps working even if your connection drops after the page loads.
On-device only
Conversion happens in your browser. No image is ever sent to us or anyone else.
No limits
No file-size cap and no batch limit, because there's no server doing the work.
Nothing stored
We can't keep what we never receive. Close the tab and every trace is gone.
