PNG to JPG
Convert PNG files to JPG at the quality you choose. Batch conversion, no uploads.
About this tool
PNG stores every pixel exactly as it was, which is why screenshots and exported graphics come out of design tools in that format. It is also why those files are large. Converting a photograph to JPG usually cuts the size by 80% or more with no visible difference, which matters when the image is going into an email, a slide deck, a marketplace listing or a page that has to load quickly.
Two things are worth knowing before converting. JPG has no transparency — every transparent pixel has to become a real colour, and here it becomes white — so a logo meant to sit on a coloured background will arrive with a white box around it. And JPG is lossy by design: it discards detail the eye is unlikely to notice, permanently. Converting a JPG back to PNG does not restore anything; the detail is already gone.
The quality slider is the whole trade-off in one control. Each converted file shows its before and after size so you can see what a given setting actually bought you, and if the result is bigger than the original — which happens with flat-colour screenshots — that is a sign the file was better off as a PNG. Everything runs through your browser's own Canvas pipeline, so nothing is uploaded and a folder of images converts as fast as your machine can decode them.
Frequently asked questions
What happens to transparent areas?
They become white. JPG has no alpha channel at all — every pixel must have a colour — so transparency has to be filled with something during conversion, and white is filled in here. If your PNG has a transparent background you want to keep, JPG is the wrong target format; use WebP, or keep the PNG.
What quality should I pick?
Around 85 is the usual sweet spot: files shrink dramatically while differences stay invisible at normal viewing size. Drop to 70 for thumbnails and images that will be displayed small. Stay above 90 only when the image will be printed, cropped hard, or edited again afterwards. Every save at any quality below 100 throws away detail permanently, so keep the PNG if you might need the original later.
Will my screenshot or logo look worse as a JPG?
Probably yes, and this is the case where PNG should win. JPG is built for photographs — smooth gradients of colour — and it handles sharp edges badly. Text, screenshots, line art, logos and anything with flat colour blocks develop visible fuzz around the edges, sometimes called mosquito noise. Photos convert beautifully; interface screenshots do not.
Why did my file get bigger instead of smaller?
Because the source was the kind of image PNG compresses well. A screenshot of mostly flat colour can be smaller as a PNG than as a JPG, since PNG stores runs of identical pixels very cheaply while JPG spends bits describing detail that is not there. Comparing the before and after sizes shown for each file tells you whether the conversion was worth it.
Can I convert several files at once?
Yes. Drop a folder of PNGs in, or select several at once, and each is converted and listed with its own download button. They are processed one after another in your browser, so a large batch takes a moment but never waits behind another user.
Are my images uploaded?
No. Each file is decoded and re-encoded by your browser's Canvas API, and no network request is made while it works. Screenshots with client data, unreleased designs and personal photos are converted without leaving your machine.
