Yes. JPEG uses lossy compression which typically results in much smaller files than PNG, especially for photographs. A 5 MB PNG photo can often be reduced to under 500 KB as a high-quality JPG.
JPG doesn't support transparency. Transparent areas in your PNG will be filled with a background colour of your choice — white by default, but you can pick black, red, blue, green, or any custom colour.
For web images, 75-85% provides the best balance of quality and file size. For print or high-quality sharing, use 92-100%. The quality presets (Web, Standard, High, Max) make this easy.
Yes. Upload as many PNGs as you need, and they'll all be converted in one batch. Download them individually or as a single ZIP file.
All conversion happens locally in your browser. Your images are never uploaded to any server — they never leave your device.
Since conversion runs in your browser, there's no hard limit. However, very large images (over 50 MP) may be slower depending on your device.
JPEG uses lossy compression, so some quality is lost. At 92-100% quality, the difference is virtually invisible to the human eye. Use the Max (100%) preset for the highest fidelity. For web use, 75-85% offers excellent quality with much smaller files.

Yes. Use the Max (100%) quality preset to preserve full detail. The converter maintains original resolution and dimensions — no downscaling. For 300 DPI print output, start with a high-resolution PNG.
No hard limit. Upload as many PNGs as you need and batch convert them all at once. Download individually or as a single ZIP file. Processing speed depends on your device since everything runs locally.
PNG uses lossless compression (keeps every pixel perfect), while JPG uses lossy compression (removes invisible details). Photos typically shrink 60-90% when converted from PNG to JPG. Graphics with flat colors may see less reduction.
