How to convert PNG to JPG

Converting a PNG to JPG re-encodes the image with lossy compression in your browser. For a photograph that is an enormous saving, because PNG stores every pixel exactly and a photo has millions of subtly different ones.

Any transparent area is filled in during the conversion, because JPG cannot store an alpha channel. For a logo or a cutout, that is usually the wrong outcome.

  • Drop the .png file in, or click the dropzone to choose it
  • The output is already set to JPG
  • Set the quality: 80 to 85 is the sweet spot for a photograph
  • Export the JPG locally, with nothing uploaded

When PNG to JPG is the right move

PNG files can be large, especially for photographs, because they store data losslessly. Converting PNG to JPG is the fastest way to cut file size when you do not need transparency, such as photos going into email, uploads, or documents.

Keep in mind that JPG flattens transparency onto a solid background, so it is not the right choice for logos or graphics that need clean transparent edges. For those, keep the PNG.

  • A photo saved as PNG is too large to upload
  • You want a lighter file for email or a document
  • The destination expects JPG specifically

Getting the quality right

The quality slider controls JPG compression. Higher quality keeps more detail at a larger size, while lower quality produces a smaller file. For most photos a high setting looks identical to the source.

The PNG is re-encoded as JPG directly in your browser, so the process is fast and private.

Tips

Getting a better result out of PNG to JPG

Specific settings and thresholds, not general advice.

  • For a photograph, this is one of the biggest size wins available: a JPG of the same photo is routinely a fraction of the PNG, because PNG is lossless and stores every pixel exactly.
  • For a logo, a screenshot, or line art, do the opposite and keep the PNG. JPG smears sharp edges and text into visible artefacts, and it will also destroy any transparency.
  • The quality slider starts at 92. On a photo, 80 to 85 is usually indistinguishable and meaningfully lighter; below 70 the artefacts start showing on skies and skin.
  • Transparent areas are filled in, not preserved. Check what colour they land as before you publish: a logo that looked fine on white will show a box on a coloured background.
  • Convert once, from the original PNG. Every JPG re-save costs quality, so a PNG that has already been through a JPG round trip is not a clean source.
Limits

What PNG to JPG does not do

The honest boundary, so you do not lose time finding it yourself.

  • It destroys transparency. JPG has no alpha channel.
  • It is lossy, so the export is not pixel-identical to the PNG.
  • It is a poor choice for text, screenshots, and line art, where the artefacts are obvious.
  • It does not resize or crop.

FAQ

Common questions

Short answers for the questions people usually have before trying a utility like this.

How do I convert PNG to JPG for free?

Upload the PNG above, set the quality you want, and download the JPG. It is free and runs locally in your browser.

Does PNG to JPG make the file smaller?

Usually yes, especially for photos, because JPG uses lossy compression while PNG is lossless. The quality slider lets you balance size against detail.

What happens to transparency?

JPG cannot store transparency, so transparent areas are filled with a solid background. Keep the PNG if you need transparent edges.

Is the PNG uploaded to a server?

No. The conversion happens in your browser and the file stays on your device.

Why is my PNG so much bigger than a JPG of the same photo?

Because PNG is lossless: it stores every pixel exactly, which is expensive for a photograph with millions of subtly different colours. JPG throws away detail the eye does not miss, and for photos that is an enormous saving.

What quality setting should I use for a JPG?

80 to 85 for a photograph. The slider defaults to 92, which is higher than most people need, and below about 70 the artefacts start to show on smooth areas like skies and skin.

Should I ever convert a screenshot from PNG to JPG?

Almost never. JPG is built for photographs, and it smears sharp edges and text into visible fringing. A screenshot, a logo, or line art should stay a PNG, or become a WebP if size matters.

What happens to the transparent background?

It gets filled in, because JPG cannot store transparency. Check the result before publishing: a logo that looked correct against white will show a visible box on any other colour.

Does converting PNG to JPG lose quality?

Yes, by design. JPG is lossy and discards detail to get small. For a photo that is a good trade; for text and sharp edges it is not.
