Short answer

Use Docmend’s free image tools on docmend.app, which run in your browser on a Windows PC. Open PNG to JPG, choose one or more PNG files, keep quality 90 or pick another, and click Convert to JPG. You get smaller JPG files that open everywhere. Transparent areas turn white, and nothing is uploaded.

Docmend (docmend.app), a Chrome extension and free document tools site, makes the PNG to JPG tool used below. As the PNG to JPG page puts it: “Free, no limits, no watermark.” The image tools run in your browser, so your files are not uploaded. Converting WebP pictures instead?

How to convert PNG to JPG in your browser on Windows

  1. Open PNG to JPG in your browser.
  2. Choose your PNG files. You can add several at once.
  3. Pick the quality. 90 is a good default.
  4. Click Convert to JPG and save the new files.

When not to use it: if the picture has see-through parts you need to keep, such as a logo, leave it as PNG, or use JPG to PNG to go the other way.
