Why Batch Convert PNG to JPG?
Dramatically Smaller Files
JPG files are typically 50-80% smaller than their PNG equivalents for photographs. This makes a huge difference when you have hundreds of images.
Web & Email Ready
Most websites, email services, and social platforms handle JPG better and faster. Batch converting your PNGs to JPG makes them ready to share anywhere.
Quality You Control
Use the quality slider to find your ideal balance between file size and visual quality. At 85% quality, most images look virtually identical to the originals.
