Convert PNG to JPG
PNG is lossless but heavy, and plenty of upload forms only accept JPG. This page takes PNG only and converts it on your own device.

PNG → JPEG
JPEG has no transparency, so clear areas are filled with this colour. PNG, WebP and AVIF keep transparency.
Keeps the capture date, camera model and other details.
PNG is a good format to keep and a poor one to upload: the same picture often weighs several times more than JPG, while many forms accept only .jpg.
This page does one job: read PNG and write JPG.
The smaller file has a price
The image is re-encoded at quality 0.9, so detail is compressed once more. Text in screenshots can soften slightly; photographic PNGs usually look unchanged.
What you get back is a much smaller file that nearly every program can open.
Transparent areas become white
This is the part worth watching. PNG often carries alpha and JPG has none, so transparent pixels are filled with white.
If the source is an icon, a sticker or artwork with soft shadows, check the edges after converting — WebP is the better target for those.
When to keep the PNG
JPG is the right answer when the form demands it or the picture is a photograph. It is the wrong answer in three cases:
- The image has transparency. Icons, logos, stickers and cut-out product shots need alpha, and JPG will paint those areas white.
- The image is mostly text. Screenshots of code, receipts or slides often end up smaller and sharper as PNG.
- You will keep editing it. Every JPG save throws detail away; a PNG master can be re-exported as often as you like.
How to use it
- Drop in PNG files. Anything else is reported and skipped, so a WebP never gets converted on a PNG page.
- Conversion starts on import. The output format is already pinned to JPG.
- Adjust quality. The slider controls the encoder and re-runs the batch when changed.
- Download. Save files individually, or take the batch as a ZIP.

Frequently asked questions
What does PNG to JPG lose?+
Two things: the alpha channel and some detail. JPG has no transparency, so transparent areas become white, and the image is re-encoded lossily at quality 0.9.
How much smaller does the file get?+
Screenshots and UI graphics commonly shrink by more than half; photographic PNGs also drop noticeably. Each card shows the real numbers.
What happens to the transparent background?+
It becomes white. If the image depends on transparency — icons, stickers, soft shadows — use WebP instead of JPG.
Can I convert a batch?+
Yes. Drop in a set of PNG files and each is processed in turn; download them individually or as a ZIP.
Are the files uploaded?+
No. Decoding, encoding and zipping all run on your own device, and no file leaves the browser.
What quality setting should I use?+
The default 0.9 is a good balance for photographs. For text screenshots, keep 0.9 so edges stay readable — dropping to 0.6 saves a little size and turns small type mushy. There is rarely a reason to go below 0.7.
Why did my JPG come out larger than the PNG?+
It happens with flat graphics. PNG compresses large areas of identical colour extremely well, while JPG must encode every block. A simple screenshot with a solid background can grow after conversion; a photograph will almost always shrink.
