Q: What happens to transparent backgrounds when converting PNG to JPG?

JPG does not support transparency, so transparent and semi-transparent pixels must be blended onto a solid color. PNGToJPG fills them with white by default, and you can switch to black or any custom hex color. Semi-transparent edges are blended smoothly against the chosen color.

Q: Are my uploaded PNG images kept private?

Yes. Your images are never uploaded. All conversion happens locally in your browser using HTML5 Canvas, and the files disappear when you close or clear the page.

Q: What JPG quality should I use?

80–90% gives an excellent balance of visual quality and small file size for photos and screenshots. Use 95–100% for maximum detail, or 60–75% when file size matters most, such as for email or web thumbnails.

Q: Can I convert multiple PNG files to JPG at once?

Yes. PNGToJPG is a batch converter: add as many PNG images as you like and download them all in one ZIP file with a single click.

PNG vs JPG: Which Format Should You Use?

PNG is a lossless format that supports transparency, making it ideal for logos, icons and graphics with sharp edges. JPG (JPEG) uses lossy compression optimized for photographs and complex images, producing much smaller files that load faster on websites and are accepted almost everywhere.
