How to Convert PNG to JPG for Free (No Upload)

To convert PNG to JPG, open ToolistHub's free Image Compressor, add the PNG images, choose JPG under Format and select Compress images, then download the JPGs. Transparent areas become white, and photos usually get much smaller. The Image Compressor works in your browser, so your images are not uploaded.

How to convert PNG to JPG

1. Open the Image Compressor on your computer or in your phone's browser.
2. Add the PNG images, up to 20 at a time, with Choose images or by dropping them on the drop area.
3. Choose JPG under Format.
4. Choose how to compress. Keep By quality and set the Quality slider, or choose To a file size, such as 50 KB, if a form sets a limit.
5. Select Compress images, then Download image, or the Download all button for one ZIP of several files.

Why convert a PNG to JPG

PNG is a lossless format: it keeps every pixel exactly, which suits logos, icons and screenshots, but a photo saved as PNG is usually much larger than as JPG. Many upload forms also accept only JPG. Converting a photo from PNG to JPG makes it smaller and accepted almost everywhere.

What happens to a transparent background

JPG has no transparency, so the transparent parts of a PNG become white. That suits forms that want a plain background. If you need the transparency, keep the image as PNG, or choose WebP, which also keeps transparency but isn't accepted everywhere.

Screenshots and text

JPG compression can blur thin lines and small text a little. For a screenshot full of text, keep the Quality slider high, or leave it as PNG if the file size allows. Photos rarely show a visible difference at a high quality.

On a Mac: Preview

On a Mac, Preview can save a PNG as JPEG: choose File > Export, then pick JPEG from the Format menu. Apple's guide to converting image file types in Preview shows the steps.

Frequently asked questions

Does converting PNG to JPG reduce quality?

A little, because JPG is a lossy format. A high quality setting keeps the loss small; the result shows the new file size so you can check.

Can I also make the JPG 50 KB?

Yes. Choose JPG under Format and To a file size, then 50 KB. The tool lowers the quality, then the pixel size if it must, until the file fits.

Can I convert many PNG files at once?

Yes, up to 20 at a time. Several converted images can be downloaded together as one ZIP file.

Are my images uploaded?

No. The Image Compressor converts the images in your browser, so they stay on your device.

Conclusion

Add your PNG images to the Image Compressor, choose JPG, and download smaller files with white where the PNG was transparent. To cut a subject out of a photo first, try the Background Remover, and read the privacy policy to see how each tool handles your files.
