Why you'd convert PNG to JPG (and when you shouldn't)

PNG stores every pixel exactly. That's great for screenshots, logos, and graphics, but terrible for the bytes-per-second budget of a web page. A PNG of a 4000-pixel-wide photograph can easily sit at 10–20 MB. JPEG's lossy compression was designed for exactly that job: it throws away imperceptible detail and can hit 500 KB or less at the same visible quality. If your PNG is a photo and the final home is a website, an email attachment, or a messaging app, switching to JPG is usually the right call. If your PNG contains crisp edges, text, flat colour, or transparency, converting will make it worse — JPEG's 8×8 DCT blocks smear letter edges into a shimmery halo and flatten alpha onto white.

What happens to transparency

JPEG has no alpha channel. Every transparent pixel has to get composited onto something opaque, and the conventional default is white. That can look fine on a product shot with a transparent cutout, and terrible on a UI screenshot with a translucent drop-shadow — the shadow merges with the white and becomes a grey smudge. If your original PNG relies on transparency, consider staying with PNG, or using WebP/AVIF (both lossy with alpha). This tool flattens transparency to white.

Quality and file-size expectations

  • A typical 12 MP photo saved as PNG is 10–20 MB. The same image at JPEG quality 85 is usually 1–2 MB with no visible loss.
  • Quality 92 is the "I promise nothing's missing" setting. Good for client-facing proofs.
  • Quality 80 is the widely-used web default. Difference from source is visible only if you pixel-peep at 200%.
  • Quality 70 is fine for thumbnails but starts to soften skin and smooth gradients.
  • Anything below 60 shows the blockiness. Don't.

File-size gotchas

A PNG of a cartoon or a flat illustration can actually be smaller than any JPEG version. That's because PNG's DEFLATE compression loves runs of identical colour — which is exactly what flat art has lots of. If your "PNG to JPG" conversion gives you a larger JPG, it's a sign the image belongs in PNG. Same goes for screenshots.

One-way trip

Every JPEG save is destructive. Once you convert a PNG to JPG, you can't recover the original. Keep the PNG if you might ever need a clean crop, a colour tweak, or a re-export at a different size. Treat JPG output as the "publish" step, not the working copy.

Alternatives to consider

  • WebP — roughly 25–35% smaller than JPEG at the same quality, and supports transparency. Browser support is universal since 2020.
  • AVIF — another 20% smaller than WebP. Safari 16+, modern Chrome and Firefox support it.
  • Run the PNG through an optimiser first. pngquant can cut PNG file size 60–70% losslessly; often you don't need JPG at all.

Privacy

Conversion happens locally in your browser via the Canvas API. Your PNG is not uploaded to any server. EXIF metadata (date, GPS, camera) is automatically dropped during the canvas round-trip — which is usually what you want when sharing.
