Tooloat

PNG to JPEG converter

Save PNG pictures as JPEG to make them far smaller for email, forms and websites. JPEG cannot store transparency, so see-through areas are filled with a color you choose. Drop one file or a whole folder, and nothing leaves your device.

Tooloat runs in your browser and needs JavaScript. It opens in a moment, and your files are processed on your device.

How it works

  1. Drop your PNG files.
  2. Set the quality and the background color.
  3. Download the JPGs, or a ZIP for a batch.

Why use it

  • Output is a standard .jpg file, which is the JPEG format.
  • Quality slider with MozJPEG optimization.
  • Choose the color that replaces transparency.
  • Bulk conversion with one ZIP.

Questions and answers

Is JPEG the same as JPG?

Yes. The three letter .jpg extension exists because older Windows versions limited extensions to three characters. The format is identical.

How small will the JPEG be?

Photos often shrink to a fifth of the PNG size or less. Screenshots and flat graphics shrink less and can look slightly fuzzy around text at low quality.

What happens to a transparent PNG?

Transparent pixels are filled with the background color, white by default.
