The basics

Not every program or website accepts every image format. Just choose the target format, drop in your images and download them converted, one by one or as a ZIP.

What it's for

  • Open iPhone photos (HEIC) on Windows or in forms
  • Turn images into space-saving WebP for websites
  • Convert PNG to JPG when a site only accepts JPG

Good to know

  • Transparency is lost when converting to JPG, it turns white
  • WebP is usually smaller than JPG and PNG
  • For print and editing, PNG is lossless

How it works

  1. 1 Drag your images into the box or choose them. Many at once are fine.
  2. 2 Check the target format.
  3. 3 Start the conversion.
  4. 4 Download the images one by one or all together as a ZIP.
