Many platforms — forms, document managers, marketplaces — only accept JPG, and a photographic PNG can weigh ten times more than necessary. This conversion solves both: small, compatible files with adjustable quality.
Remember JPG has no transparency: transparent PNG areas are automatically filled with white. To keep a transparent background, convert to WebP instead.
How it works
- 1
Drag your PNGs into the upload zone.
- 2
JPEG is preselected; adjust quality if you like.
- 3
Download the resulting JPGs or the ZIP.
Frequently asked questions
What happens to my PNG’s transparency?
JPG does not support transparency, so transparent areas are filled with white. To keep them, convert to WebP — it preserves them and weighs less.
How much smaller will the JPG be?
For photographic images, typically 70–90% smaller. For flat graphics the saving is smaller and WebP is usually the better choice.
Are my images uploaded to a server?
No. All processing happens inside your browser using the Canvas API: your files never leave your device, there are no upload queues, and the tool even works offline once the page has loaded.
