Using a photo editor

Although photo editing programs like Adobe Photoshop can be daunting and expensive, a simple, free photo editor works perfectly for converting images to different formats. Microsoft Windows includes the program Paint, and Mac users may use the Preview program.


Mac users who are familiar with Microsoft Paint may find the Paintbrush program helpful, as it is quite similar. The image conversion steps are the same as the Converting in Windows section.

Converting in Windows

  1. Open the photo in Microsoft Paint.
  2. Click the file Menu Microsoft Paint menu button button in the upper-left corner of the screen.
  3. Select Save As from the drop-down menu.
  4. In the box next to Save as type:, click the down arrow.
  5. Select your new file format and click Save.

Converting in macOS

  2. Click the file Menu in the upper-left corner of the screen.
  3. Select Export... from the drop-down menu.
  4. In the box next to Format:, click the down arrow and select your new file format.

For many file types, Mac users can change the file name extension, and the image converts automatically.
