Smaller files for photos and sharing

PNG is great for graphics but heavy for photos — a PNG photo can be five times the size of the same image as JPG. Converting to JPG makes files easy to email, upload and share, and it's the format almost every form and website accepts.

Because JPG can't store transparency, you choose the colour that fills transparent areas (white by default) instead of getting the black background many converters produce. Set the quality, convert one file or a hundred, and download them as a ZIP.

How to convert PNG to JPG

  1. 1

    Add PNG files

    Choose, drag in or paste one or more PNG images.

  2. 2

    Set quality and background

    90% quality looks identical to the original for most images. Pick the colour for transparent areas.

  3. 3

    Convert and download

    Download each JPG, or all of them as a ZIP.

Common uses

  • Uploading screenshots: Turn large PNG screenshots into light JPGs for tickets, chats and email.
  • Forms that need JPG: Application portals often accept only .jpg files.
  • Photo exports: Shrink photos that an app saved as PNG.

Tips and good to know

  • For logos, icons and images with text, PNG is often the better choice — JPG can add faint smudges around sharp edges.
  • Need an exact size in KB? Run the JPG through the Image Compressor with a target size.
  • If you want to keep transparency but still get a small file, convert to WebP with the Image Converter.

Frequently asked questions

Why does my PNG turn black when converted to JPG?

JPG has no transparency, and many converters fill see-through areas with black. Here you choose the fill colour, which is white by default.

What quality should I use?

85–90% keeps photos virtually identical to the PNG. Around 75% gives much smaller files that still look good on screen.

Is PNG to JPG conversion lossless?

No. JPG uses lossy compression, which is why the files are so much smaller. At high quality settings the difference is very hard to see.

Can I convert multiple PNGs to JPG at once?

Yes. Add them all and download the results as a single ZIP file.
