How to convert PNG to JPG

Short answer

Open the PNG in an image converter, choose JPG as the output, set quality around 80-90%, and download. JPG has no transparency, so any transparent areas are filled with a background color.

When converting PNG to JPG makes sense

PNG is lossless and often large, which is perfect for screenshots and graphics but wasteful for photographs. Converting a photo saved as PNG to JPG can cut the file size by 70-90% with no visible difference. See PNG vs JPG for choosing between them.

Convert a PNG to JPG

  1. Add the PNGDrop the file into the image converter. It decodes inside the browser tab.
  2. Choose JPGSet the output format to JPG (also written JPEG).
  3. Set quality80-90% is a good balance of size and clarity for photos.
  4. DownloadSave the JPG. The original PNG is left untouched.

Transparency is filled inJPG has no alpha channel. Transparent areas of a PNG become a solid color (usually white) after conversion. If you need transparency, keep the PNG or use WebP. See what is an alpha channel.

Keep the quality high

  • Convert from the original PNG, not a re-saved copy
  • Avoid quality below ~70% for photos with fine detail
  • Do not repeatedly re-save the JPG — each save discards a little more detail
  • For logos, line art, or screenshots, stay on PNG instead

Questions

Does converting PNG to JPG reduce quality?

JPG is lossy, so some detail is discarded, but at 80-90% quality the difference is invisible for most photos while the file shrinks dramatically. For flat graphics and text, PNG stays sharper.

What happens to a transparent PNG background?

It is flattened to a solid color because JPG cannot store transparency. Convert to WebP instead if you need a transparent background at a smaller size.

Do these tools upload my images?

No. Utilumo's image tools decode, edit, and export pictures inside the browser tab. The files are never uploaded or stored on a server.
