PNG to JPG Converter

Convert PNG Images to JPG

Convert PNG images to JPG, one at a time or a whole folder at once, and make photos far smaller. See-through areas turn white. It all happens in your browser, so nothing is uploaded.

How to convert PNG to JPG

  1. Check the quality

    JPEG is already selected on this page. The quality starts at 85%, or whatever you used last time, which suits photos. For screenshots and images with small text, see the tips below.

  2. Add your PNGs

    Drop PNG files onto the box above, or click it to choose them. Add one image or every file in a folder, then press Process.

  3. Download your JPGs

    Save each file with its download button, or press Download ZIP to get them all in one file. diagram.png becomes diagram.jpg.

What changes when a PNG becomes a JPG

PNG is lossless: it stores every pixel exactly, which keeps graphics sharp but makes photos large. JPG makes files smaller by discarding fine detail you’re unlikely to notice. Converting applies that compression once, at the quality you choose.

  • Transparent areas turn white. JPG can’t store transparency, so the converter fills see-through areas with white before saving. Soft edges and shadows blend into the white, as if the image had been placed on a white page.
  • The size in pixels stays the same. A 1280 × 800 PNG gives a 1280 × 800 JPG. To make it smaller in pixels too, use Resize.
  • Hidden details aren’t copied. Text and EXIF data stored in the PNG, such as the program that made it, are left out: the JPG holds the picture only.

Photos shrink; screenshots and logos don’t

How much you save depends on what’s in the PNG. These were converted on this page at the default 85% quality:

PNG imagePNGAs JPG
Photo of a zebra, 512 × 512529 KB61 KB, 88% smaller
Photo of a parrot, 512 × 512500 KB41 KB, 92% smaller
Web page screenshot, 1280 × 800103 KB81 KB, 22% smaller
Same screenshot, 2560 × 1600240 KB197 KB, 18% smaller
Flat four-colour graphic, 512 × 5121.8 KB2.5 KB, 34% bigger
Logo on transparency, 400 × 3001.2 KB4.3 KB, about 3.5 times bigger

Photos are full of subtle, irregular detail that JPG compresses well, so a PNG photo typically ends up around 90% smaller. Screenshots, charts, text and logos are made of flat colour and hard edges. PNG already stores those compactly, and JPG handles them badly: the saving is small or negative, and faint smudges appear around letters and lines.

Should you convert screenshots to JPG?

Usually not. At 85% the web page screenshot above lost only a fifth of its size and gained blurred halos around its text and buttons. At 90% it was just 9% smaller than the PNG. At 95% it was 12% bigger, and faint colour fringes still showed around the buttons; only at 100% did they disappear, by which point the JPG was more than twice the size of the PNG.

If an upload form insists on JPG, use 90% or more for anything with small text to keep the smudging down. If you simply want a smaller file for a website, PNG to WebP does better and keeps transparency: the same screenshot became 42 KB as WebP.

Choosing the quality for PNG to JPG

  • 85% (the default): right for photos. The zebra photo went from 529 KB to 61 KB without visible loss at normal size.
  • 90 to 95%: for screenshots, diagrams and images with small text, if they must be JPGs. Smudges are fainter than at 85%, though not gone.
  • 100%: rarely worth it for photos. The zebra photo came out at 235 KB, nearly four times the size of the 85% version, with no difference you could see.

Each converted file shows its old and new size. To try another setting, move the slider and press Rerun with new settings.

Frequently asked questions

What happens to a transparent background when I convert PNG to JPG?

It turns white. JPG can’t store transparency, so see-through areas are filled with white and soft edges blend into it. To keep the background transparent, keep the PNG or use PNG to WebP.

Is JPG the same as JPEG?

Yes. They’re two names for the same format; .jpg became common because early versions of Windows only allowed three-letter file extensions. The button on this page says JPEG, and files are saved with the .jpg extension.

How much smaller will my PNG be as a JPG?

For photos, typically around 90% smaller at the default quality. Screenshots shrank by only about a fifth in our tests, and small logos and flat graphics came out bigger. Each result shows its old and new size, so you can check.

Why is my JPG bigger than the PNG?

PNG stores areas of flat colour very compactly, so simple graphics, icons and logos are already small, and JPG isn’t designed for them. A 1.8 KB four-colour graphic became 2.5 KB. Keep images like that as PNG.

Why does text look blurry after converting PNG to JPG?

JPG compression softens sharp edges and blurs colour slightly, which shows most around letters and thin lines. Raising the quality to 90 or 95% makes it fainter; press Rerun with new settings to try. For screenshots and diagrams, PNG is usually the better format anyway.

Can I turn the JPG back into a PNG?

Yes, with JPG to PNG, but the detail JPG discarded won’t come back, and neither will the transparency: white areas stay white. Keep your original PNGs if you might need them.

Can I convert a whole folder of PNGs to JPG at once?

Yes. Click the box, select every file in the folder (Ctrl+A on Windows, Cmd+A on a Mac), press Process, then Download ZIP to save all the JPGs in one file, converted_images.zip.

Is my PNG uploaded when I convert it?

No. The conversion happens in your browser, on your own device, so your PNGs and the JPGs made from them are never sent anywhere.
