Getting the best result
- Use WebP on websites. Product photos and cut-outs on transparent backgrounds gain the most.
- Keep the PNG for editing. WebP here is lossy: edit the PNG, then convert again.
- Logos and text? Choose Best so thin lines and letters stay crisp.
- Resize too. An image bigger than its slot on the page wastes most of its weight.
Your images never leave your device
The converter runs in your browser: images are read and saved on your computer or phone, and nothing is sent to our server. Location, camera and date details are not copied into the new file.
