Is converting PNG to JPG free and private?

Yes. The conversion runs inside your browser, so the PNG is read from disk into the page and never sent to a server. There is no account and no daily cap, and it keeps working with your Wi-Fi switched off.

Will the JPG be smaller than the PNG?

For a photograph, almost always — often dramatically, because PNG stores every pixel losslessly while JPG discards detail your eye will not miss. For a flat graphic, logo or screenshot the PNG may already be small, and there JPG saves little and can look worse.

What happens to transparency when I convert PNG to JPG?

It is lost. JPG has no alpha channel, so any transparent areas of the PNG are flattened to a solid background — white here. If you need to keep transparency, convert to WebP instead, which supports it.

Does converting to JPG lose quality?

JPG is lossy, so re-encoding removes some detail. At the default quality it is not visible at normal viewing sizes on a photograph. Raise the quality slider toward 1.0 for a near-identical file that saves less, or lower it for smaller files with visible loss.

Can I convert many PNG files at once?

Yes. Drop in a whole folder — hundreds at once is normal. There is no daily cap, because the work happens on your own device. Save them individually or download the batch as one zip.

PNG to JPG,
smaller, and it opens everywhere.

A PNG photo is usually many times heavier than it needs to be, because PNG throws nothing away. JPG re-encodes the same picture into a fraction of the bytes and opens on anything ever made. The conversion runs in this page, on your machine — the file never leaves your device. There's one trade worth knowing before you press go.

The short version

If your PNG is a photograph — a picture of a person, a place, a screenshot of something with a photo in it — JPG is almost certainly what you want. The file gets far smaller for a difference your eye can't find, and every program and website on earth can open it. That's the whole reason JPG has outlived a dozen "better" formats.

The catch is two things JPG deliberately doesn't do. It's lossy: it shrinks a photo by discarding detail, so it's the wrong tool for a diagram or logo with hard edges, where the discarding shows. And it has no transparency: any see-through part of your PNG gets filled in with a solid colour — white — because JPG has nowhere to store "transparent".

Open the converter

Convert a PNG to JPG in three steps

Open the converter. The button above lands you on the tool with JPG already selected — nothing else to set.
Add your PNGs. Drop them on the page, paste from the clipboard, or choose a whole folder. They're read straight into the tab; no upload happens.
Save the JPGs. Each one is re-encoded on your device. Save row by row, or grab the lot as a single zip.

When PNG to JPG is the right call

Any photograph saved as PNG. Cameras and phones sometimes hand you PNGs, and design tools love exporting them. As a photo, that PNG is carrying vastly more bytes than the picture needs. JPG fixes exactly that.
Files that have to travel. A big PNG is too heavy to email and slow to upload. The JPG version sails through forms and inboxes that would choke on the original.
Anything going somewhere old or fussy. A print shop's uploader, a legacy CMS, an ancient viewer — JPG is the format none of them will reject.

When to keep the PNG instead

It has transparency you need. A logo or sticker with a see-through background loses that background to flat white in JPG. If you need the transparency, convert PNG to WebP — it keeps it.
It's a screenshot, diagram or line art. JPG smears the crisp edges where text meets background. On flat, sharp-edged images PNG both looks better and is often already small, so JPG buys you little.
You'll edit and re-save it repeatedly. Every JPG save loses a little more. Work in PNG, export to JPG once at the end.

The honest caveats

Nothing uploads, and you can check that. The conversion runs in this page. Press F12, open the Network tab and convert a PNG: no request goes out. Or turn off your Wi-Fi and convert anyway — it still works, because there's nothing on the other end of the wire.
Transparency becomes white. This isn't a bug; JPG simply can't store transparency. If your PNG had a transparent background, expect solid white in its place. WebP is the format to pick when that matters.
JPG can't un-lose what PNG kept. Converting doesn't add detail — it makes a smaller copy by dropping some. Going back to PNG later won't restore anything; it'll just be a larger file of the already-reduced picture.
EXIF metadata is dropped — the image is decoded to pixels and re-encoded, so any embedded data doesn't come along. Rotation is applied, so pictures come out the right way up.

Questions people actually ask

Is PNG to JPG free, with no limit?: Yes — no account, no daily cap, no file limit. The work happens on your device, so the only ceiling is your device's memory, and hundreds of files at once is normal.
Why would my JPG look worse than the PNG?: Only if the PNG was flat graphics or text, where JPG's lossy compression smears sharp edges. On a photograph you won't see the difference at the default quality. If the edges matter, keep the PNG.
My PNG has a transparent background. What happens?: The transparent areas turn white, because JPG has no alpha channel to store them. If you need the transparency kept, convert to WebP instead.
Are my images uploaded to a server?: No, and you don't have to take that on faith. Turn off your Wi-Fi and convert one. It works, because there was never anywhere for the file to go.
Can I control how small the JPG gets?: Yes. The quality slider is the real lever — 0.8 is a safe default, lower for smaller files, higher to stay pristine. You can also cap the longest side to shed pixels a screen never shows.
