Strangely enough, even some experienced Mac users underestimate the Preview utility, which has been included in the OS X software suite a long time ago. Its name is deceptive: this program has sufficient tools for group editing, including file conversion mode.

Preview application traditionally does not enjoy the great love of Mac users. And it’s completely in vain, because it can not only display and edit pictures, but one very useful thing – convert them from one format to another.

Preview works with any number of images and all popular formats. In particular, GIF, ICNS, JPEG, JPEG-2000, BMP, Microsoft Icon, OpenEXR, PDF, Photoshop PSD, PNG, SGI, TGA and TIFF are supported.

How to Convert Photos to Another Format on Mac

  • In the Finder, select a group of images, right-click on them and select “Open”. Alternative method: click “Cmd” + “O” or drag images to the View application icon in the Dock;
  • Click on any of the photos in the window on the left and press the “Cmd” + “A” key combination to select all of them.Alternative method: in the menu bar “Edit” -> “Select All”;
  • On the menu bar, click “File” -> “Export” or “Export Selected Images”;
  • In the window that appears, click “Settings” and select the format in which you want to convert the file;
  • To open the full list of formats, hold down the “Option (Alt)” button on the keyboard and click on the Format drop-down menu;
  • In the same place, select the path to save convertible files (for example, to the desktop);
  • The process starts, a progress bar appears on the screen. If there are a lot of images, the conversion may take some time, but in general, everything is done very quickly.


This feature exists in all versions of macOS or OS X, the only difference, except for the appearance, is that you will use the “Export” or “Save As” function. Similar work happens with other formats. And you can upload files in several formats simultaneously in the Preview. The main thing is that they are all supported by the utility. And do not forget about the focus with the option key in the export dialog.
