Why convert PNG to JPG?

PNG to JPG conversion is the fastest way to shrink a screenshot or scanned image that's grown too large to email, upload, or store comfortably. PNG is a lossless format, which is great for accuracy but terrible for file size once a picture has photographic detail or smooth gradients — every pixel gets stored exactly, with nothing thrown away.

Here's a concrete example. A 4000×3000 pixel PNG screenshot — the kind a modern laptop or phone produces by default — often weighs 6-9MB. Convert that same image to JPG at 85% quality and it typically lands around 500-700KB: roughly a 90% size reduction. That's because JPG's lossy compression is far more efficient than PNG's lossless compression for photographic and gradient-heavy content, discarding detail the eye barely notices while keeping the image visually intact.

Transparency caveat

JPG has no alpha channel. If your source PNG has transparent areas, they'll be filled with solid white during conversion, and there's no way to recover them afterward. If you need to keep transparency, stay with PNG format instead of converting.

How to convert PNG to JPG

  1. Drop your .png file into the upload box above, or click to browse.
  2. Confirm JPEG is selected as the output format (it's pre-selected for you).
  3. Adjust the quality slider — 85% is a good default for photos and screenshots.
  4. Click Convert, then download your new, much smaller .jpg file.

Frequently asked questions

Why is my PNG file so much bigger than a JPG?

PNG is a lossless format, so it must store every pixel exactly as it was captured with no data thrown away. JPG uses lossy compression that discards visual information a viewer is unlikely to notice, which is far more efficient for photos and gradients and typically produces a much smaller file.

Will I lose image quality converting PNG to JPG?

JPG is lossy, but at 85% quality or higher the loss is imperceptible for photos. PNG's pixel-perfect exactness is mainly useful for text, line art, or screenshots meant for further editing, not everyday photo sharing.

What happens to transparent PNGs?

JPG has no alpha channel, so any transparent areas in your PNG are filled with a solid white background during conversion. If you need to keep transparency, stay with PNG format.

Is there a file size limit?

There's a 10000x10000 pixel dimension cap, which is tied to browser memory rather than a server limit, since nothing is ever uploaded — see our Privacy Policy for details.
