Convert PNG to JPG
Usually you're here because a PNG is enormous. A full-resolution photograph saved as PNG can easily be 15MB; the same image as a JPG is often under a megabyte, and you genuinely cannot tell them apart.

Why PNG files get so big
PNG is lossless — it reproduces every single pixel exactly. That's perfect for a logo with hard edges, and enormously wasteful for a photograph, where millions of subtle tonal variations each have to be stored faithfully.
JPG is lossy: it discards the detail your eye is least likely to notice. On photographs that's an extraordinarily good trade. On a screenshot full of text, it isn't — which is the one case where you should stay on PNG.
| What it is | Convert to JPG? |
|---|---|
| Photograph saved as PNG | Yes — big saving, no visible loss |
| Screenshot with text | No — text goes fuzzy |
| Logo or icon | No — keep the transparency |
| Diagram or chart | No — hard edges suffer |
| Scanned document photo | Yes, at high quality |
Common questions
What happens to a transparent background?
It's flattened onto white, because JPG has no alpha channel. If the transparency matters, keep the file as PNG — or use WebP, which is smaller than PNG and keeps transparency.
How much smaller will it be?
For photographs, commonly five to ten times. For flat graphics, far less — sometimes the JPG is even bigger, which is a good sign you should have stayed on PNG.
Can I guarantee it comes in under a specific size?
Yes — set a target size in KB or MB and you'll get the best-quality version that fits. See compressing to an exact file size.
Will it change my original PNG?
No. Converting creates new files; your originals are read and left alone.
