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.

1

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.

2

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.

3

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.

§ 01

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.

§ 02

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.

§ 03

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.

§ 01

On-device only

Conversion happens in your browser. No image is ever sent to us or anyone else.

§ 02

No limits

No file-size cap and no batch limit, because there's no server doing the work.

§ 03

Nothing stored

We can't keep what we never receive. Close the tab and every trace is gone.

Frequently Asked Questions

Is this PNG to JPG converter free?
Yes — completely free with no signup, no watermark and no daily limit. Because the conversion runs in your browser instead of on our servers, there's no per-file cost for us to pass on to you.
Do my images get uploaded anywhere?
No. Your PNG files are converted entirely on your own device using the browser's canvas. They never touch a server, which is why there are no size or count limits — and why it still works offline after the page loads.
What happens to my transparent background?
JPG can't store transparency, so transparent areas are filled with a solid color. This tool uses white by default and lets you choose black or any custom color before converting — so you're never surprised by a black box.
Will I lose quality converting PNG to JPG?
JPG is lossy, but at quality 90 the result is visually identical for most images. Lower the quality only when you want an even smaller file and a little softening is acceptable.
How much smaller will the JPG be?
Usually several times smaller — screenshots and flat graphics shrink the most, often from megabytes to a few hundred kilobytes. The tool shows the exact before and after size for each file.
Can I batch convert many PNGs to JPG?
Yes. Add a whole folder, convert them in one pass, and download everything as a single ZIP. There's no 20 or 200-file cap that upload-based tools impose.
How do I convert PNG to JPG on Windows or Mac?
Open this page in any browser and drop the files in — no install and no codec needed. It works exactly the same on Windows and Mac.
Can I convert PNG to JPG and keep transparency?
No — JPG fundamentally can't hold transparency. If you need it, keep the PNG. Convert to JPG only when a solid background color is acceptable.
