Convert PNG to JPG in your browser. JPG files are much smaller than PNG for photographs, which makes them faster to load and easier to share. Transparent areas are flattened onto a background colour you can choose.
Why convert PNG to JPG?
PNG is lossless, which makes it large for photographs. JPG uses lossy compression tuned for photos, so converting a photographic PNG to JPG often shrinks it dramatically with no visible quality drop. That makes it faster to upload, easier to email, and lighter on storage — and some upload forms accept only JPG.
What happens to a transparent PNG?
JPG cannot store transparency. When you convert a transparent PNG, the see-through areas are filled with a solid background colour — this tool lets you choose it (white by default) so you never get the black fringing a naive converter produces. If you need to keep transparency, convert to WebP instead.
How to convert an image
- 1Upload your PNG file.
- 2Pick a JPG quality level and, if the PNG is transparent, a background colour.
- 3Compare the size saved against the original.
- 4Download the smaller JPG.
When to use PNG to JPG
- Shrinking a large PNG photo so it uploads or emails easily.
- Meeting a JPG-only upload requirement.
- Reducing storage for photos where transparency is not needed.
Frequently asked questions
What happens to a transparent PNG?
JPG cannot store transparency, so transparent areas are filled with a solid background colour. The tool lets you choose it — white is the default — so you never get black fringing.
How much smaller will the JPG be?
For a photographic PNG, often dramatically smaller. The tool shows the real achieved size so you can see the exact saving.
Is quality lost converting to JPG?
JPG is lossy, so there is some loss, but at high quality it is invisible. You control the quality level before downloading.
