How it works

  1. Drop your PNG — the Export dialog opens with JPEG selected.
  2. Set the quality and check the estimated file size.
  3. Click Download to save the JPG.

Why convert PNG to JPG

PNG is lossless, which is perfect for graphics but wasteful for photographs: a photo saved as PNG is often several times larger than the same photo as JPEG. Converting makes it practical to email, to upload through forms with size limits, or to post on sites that only accept JPG. JPEG works by discarding fine detail the eye barely notices, so it suits photos, soft gradients and scanned pictures far better than flat graphics.

What happens to transparency

JPEG can’t store transparent pixels. When you export a PNG with a transparent background — a logo, an icon, a cut-out product — the transparent parts become white. That is usually what you want for documents and white web pages. If the image will sit on a colored background, keep it as PNG or WebP, or choose New layer in the Layer menu, drag that layer below the image in the Layers panel, fill it with the color you need using the Fill tool, and then export to JPG.

Choosing JPEG quality

The quality slider runs from 10 to 100. For photos, 80–90 gives files that look the same as the PNG at normal size. If the PNG is a screenshot, a chart or anything with small text, JPEG tends to create fuzzy halos around sharp edges; use 90 or higher, or consider staying with PNG. The file-size estimate updates as you move the slider, so you can see exactly what each step saves before you click Download.

Frequently asked questions

Does converting PNG to JPG reduce quality?

Slightly, because JPEG is a lossy format. At quality 85 or above the difference is hard to see in photos. Graphics with flat colors and sharp lines show artifacts sooner, so check the result and keep PNG if crisp edges matter.

Why did my transparent background turn white?

JPEG doesn’t support transparency, so the editor fills transparent areas with white when it saves a JPG. To keep the background see-through, export as PNG or WebP instead.

Can I convert JPG back to PNG?

Yes — open the JPG and choose PNG in the Export dialog. The file is lossless from then on, but detail already removed by JPEG compression doesn’t come back, and the PNG will usually be larger.
