2. Choose the settings you need, then press the action button.
3. Check the preview and download the new image.

Tips for best results

• Start from the largest original you have; thumbnails made from already small images look soft.
• Everything runs in your browser, so you can use Image Thumbnail even on a slow connection once the page has loaded.

Limits to keep in mind

• Files are processed in your browser, so very large files depend on your device memory and may be slow. The limit is 50 MB per file.
• Animated images keep only their first frame. JPG output cannot keep transparency, and lossy formats discard a small amount of detail.
