Getting the best result
- Use WebP on websites. Lighter images load faster and help your page speed score.
- Keep the JPG for printing and sharing. Some apps and services still expect JPG.
- Resize too. A 4000-pixel photo in a 1200-pixel slot wastes most of its weight.
- Check the result. High suits most photos; choose Best for fine detail.
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.
