- Add your PNG files by choosing them or dropping them on the box.
- Set the JPG quality and, for see-through PNGs, the background color.
- Convert and download the JPGs, one by one or as a ZIP.
Why convert PNG to JPG?
PNG is lossless: it records every pixel exactly. That's perfect for some images but wasteful for photographs, where tiny variations in color and noise make the file huge. JPG was designed for photos. It throws away detail the eye barely notices and in return produces files that are often a fraction of the size. A phone photo that weighs 8 MB as PNG may land around 1–2 MB as a JPG at high quality, and the savings grow further at lower settings. The exact ratio depends on the picture.
Smaller files mean faster uploads, emails that don't bounce and pages that load quickly. Many forms also accept JPG only.
What happens to transparency
JPG has no concept of see-through pixels. Every pixel must have a solid color. When a PNG with a transparent background (a logo, a cut-out product shot, an icon) becomes a JPG, the transparent areas have to be filled with something. This converter lets you choose that color: white is the default, black is one click away and the color picker allows any other shade, for instance the exact background color of the web page where the image will appear.
Semi-transparent edges, such as soft shadows or anti-aliased outlines, are blended with the chosen color, so the result looks natural against that background. If you later need the cut-out again, keep the original PNG; the transparency can't be recovered from the JPG.
When to keep PNG instead
| Image type | Better format | Why |
|---|---|---|
| Camera photos, scanned pictures | JPG | Much smaller with no visible difference |
| Screenshots with text | PNG | JPG adds fuzzy halos around letters |
| Logos, icons, flat graphics | PNG | Sharp edges and transparency stay intact |
| Diagrams and charts | PNG | Large single-color areas compress well losslessly |
If a screenshot is simply too big, try Compress PNG first. It usually shrinks it a lot while staying sharp.
Typical uses
- Online marketplaces and classifieds often cap image size and prefer JPG. Converting product photos that your phone or editor saved as PNG makes them upload faster.
- Email attachments: a handful of PNG photos can exceed a mail provider's attachment limit, while the same set as JPG usually fits.
- Documents and slides: inserting JPGs instead of PNG photos keeps Word files and presentations from ballooning in size.
Converting many files is as quick as converting one. Add a whole folder, and you'll get every JPG back in a single ZIP.
Private by design
The conversion runs locally in your browser using its built-in JPG encoder. Your PNGs aren't sent to a server, so confidential screenshots, invoices or design drafts stay on your machine.

Frequently asked questions
What quality setting should I use?
The default of 90% looks the same as the original for photos. For web use, 75–85% gives smaller files with little visible change. Screenshots with text show artifacts sooner, so keep them higher or leave them as PNG.
My JPG is bigger than the PNG. Why?
That happens with simple graphics, such as a logo on a flat background. PNG compresses large uniform areas very efficiently, while JPG is tuned for photos. For that kind of image, PNG is the better format.
Can I convert a transparent PNG and keep the transparency?
Not as JPG. If you need a smaller file that keeps transparency, choose WebP or AVIF as the output instead; both support see-through areas.
Does converting remove hidden data?
Yes. The JPG is created from the pixels only, so text chunks and other metadata stored in the PNG are not carried over.
Can I choose a background color other than white?
Yes. Use the color picker next to the Background option, or tap Black. The chosen color fills every transparent pixel in all files of the batch.
