PNG to JPG

How to use the PNG to JPG

1. Choose PNG files, or drag and drop them onto the box. One file or a whole batch.
2. Set the JPG quality and, for transparent PNGs, the background colour. Files convert straight away and update when you change a setting.
3. Download files one by one, or use Download all. Clear all removes them from the page.

Examples

• A screenshot or photo saved as PNG that is too big to email or upload. As a JPG at 90% it is usually several times smaller, at the same width and height.
• A logo with a transparent background that has to go into a form that only takes JPG. The transparent area becomes white, or the colour of the page it will sit on.
• A diagram with sharp text may look slightly blurred as a JPG. Keep it as PNG, or shrink it with the Image Compressor instead.

PNG vs JPG

PNG is lossless and supports transparency, which makes it ideal for screenshots, logos and graphics, but photos saved as PNG are large. JPG uses lossy compression designed for photos, so files are much smaller, but it has no transparency and can blur sharp edges and text.

What happens to transparency

Because JPG can’t store see-through pixels, each one is blended onto the background colour before the image is saved. Semi-transparent edges, such as soft shadows, blend smoothly into that colour. White suits most documents; pick your page colour if the image will sit on a coloured background.

Quality

The quality setting controls JPG compression. 90% is hard to tell from the original; 70–80% gives much smaller files for photos. The width and height never change. To change the size too, use the Image Resizer.

Conversion runs in a background worker in your browser. Your images are never uploaded, and converted files exist only in your browser’s memory until you download them or leave the page.
