PNG to JPG turns PNG images, such as screenshots, exports from design apps and downloaded graphics, into JPG files that are smaller and accepted by almost every website, form and email client. The converter reads each PNG in your browser and encodes it as a JPG at the quality you choose.
JPG has no transparency. Where a PNG has transparent or semi-transparent pixels, the tool fills them with a background colour: white by default, black, or any colour you pick. Without that step many converters produce black backgrounds behind logos, which is the most common complaint about PNG to JPG conversions.
The quality slider decides the file size. At 90% (the default) photos look the same as the PNG and are usually far smaller. Screenshots with sharp text and flat colours compress less well as JPG and can show faint smudges around letters at lower settings, so keep the quality high for those, or keep them as PNG. Before you convert, the tool shows the expected size of your first image so you can tune the slider for free.
PNG files of photos and large screenshots are often several megabytes, too big for upload limits on job portals, government forms and email. Saving them as JPG usually cuts the size by a large margin with no visible change, and choosing the background colour yourself avoids the black-box problem on transparent logos.

JPG can't store transparency, and many converters treat transparent pixels as black. This tool fills them with the background colour you choose, white by default, so logos and cut-outs keep a clean background.
For photos, 80 to 90% looks the same as the original at a much smaller size. For screenshots, charts and text, use 90% or more to avoid smudges around sharp edges. The size preview shows the result for your first image before you spend a run.
For photos, almost always, often by a large margin. Small graphics with a few flat colours can sometimes come out larger as JPG; the size preview tells you before you convert.
Yes. The tool works in Safari on iPhone and Chrome on Android. Choose the PNGs, convert, then tap Download. Screenshots on iPhone are PNGs, so this is a quick way to make them smaller before sharing.
Yes. Every PNG is converted on your own device and never uploaded. Our server only records that the tool was used, to apply the daily free run.
Up to 30 files per batch, each up to 60 MB. Images above about 16.7 megapixels are scaled down to fit the browser's canvas limit.
