PNG to JPG
Make a heavy PNG photo small — never uploaded.
How it works
Three steps, and nothing leaves your device.
-
1
Drop the PNG in
It is read in the page; nothing is sent anywhere.
-
2
It is re-encoded as JPG
Quality is kept at 92%, which is visually indistinguishable on photographs.
-
3
Download the JPG
Usually a fraction of what the PNG weighed.
What changes when a PNG becomes a JPG
- Photographs get dramatically smaller. PNG is lossless, which means it stores every pixel exactly — excellent for a logo, wasteful for a photograph where no eye can tell the difference. A camera photo saved as PNG routinely drops to a fraction of its size as a JPG that looks identical.
- Transparency is filled with white, not kept. JPG has no alpha channel at all. Anywhere the PNG was see-through becomes white — deliberately white rather than black, because white is what a transparent logo is almost always sitting on. If you need the transparency, convert to WebP instead.
- It is a one-way trip. JPG throws away detail to get small, and converting the result back to PNG cannot bring it back. Keep the PNG if it is your master copy and treat the JPG as the version you send.
- Screenshots and flat graphics are the exception. On text, sharp lines and large blocks of one colour, JPG produces visible fuzz around the edges and often is not much smaller. Those are exactly the images PNG is for — converting them is usually the wrong move.
Frequently asked questions
How much smaller will it get?
On a photograph, usually a large reduction — the exact figure depends on the picture. On a screenshot or a flat graphic, sometimes barely any, and occasionally larger.
What happens to transparent areas?
They are filled with white. JPG cannot store transparency of any kind.
Does it lose quality?
JPG is lossy by design. This uses 92% quality, where the loss is invisible on a photograph at normal viewing size.
Is my image uploaded?
No. The conversion runs in your browser and the file never leaves your device.
