Good to know

The PNG to JPG converter converts up to 20 PNG images at once directly in your browser via canvas into JPG, with a quality slider from 10 to 100 and a default of 90. Since JPG has no alpha channel, transparent areas are automatically filled with a white background.

Multiple results can be downloaded together as a ZIP, with a visible size comparison per file. Transparency is irreversibly lost in JPG and replaced by the white background.

Typical use cases

Save a transparent logo as a photo with a white background

Convert a PNG with transparency to JPG when a target application only accepts photos without an alpha channel.

Shrink PNG screenshots for smaller file sizes

Use a lower quality value to significantly shrink PNG screenshots before sending them by email.

Tips for better results

Check transparent images before converting

Since transparency is replaced by a white area, check beforehand whether this fits logos or icons meant for a colored target background.

Use the quality slider to control file size

Reduce quality below the default of 90 when a smaller file matters more than maximum image fidelity.

Features

  • Quality slider with a default of 90

    Adjust JPG quality between 10 and 100 to balance file size and image fidelity.

  • Automatic white background

    Transparent areas are automatically filled with white, since JPG doesn't support transparency.

  • Local processing

    The conversion happens via canvas directly in the browser, without uploading the images.
