Save Images as GIF & Other Image Formats in Preview for Mac OS X

Aug 29, 2012 - 6 Comments

Preview in Mac Preview is a great basic image editing app bundled with Mac OS X, but newer versions from OS X have simplified the available image Export Format options down to JPEG, JPEG 2000, OpenEXR, PDF, PNG, and TIFF. Or at least that’s what you see on first glance, but it turns out you can still access all the traditional image format options from the Save, Save As, and Export screens just by using a simple key modifier when saving a file in Preview app on the Mac.

This is kind of a little known secret (well, at least until we told you about it!) but once you learn how to use it, you’ll be able to reveal many image format save options in the Preview OS X application.

How to Access All Image Format Export Options in OS X Preview

The secret to access the additional image format export options is holding down the Option key when clicking on the Format menu within the Save dialog box. Not sure where that is? No worries, here’s exactly what you’ll want to do:

  1. With any image open in Preview app, go to the “File” menu and choose either ‘Save As’ or ‘Export’
  2. At the Save screen, hold down the Option key and click into the “Format” menu – this will reveal all additional image file types that you can save as
  3. Choose your desired image file format as usual and save the file like any other

Here’s how this looks in modern versions of OS X, with Preview Format options offering the image file formats including: JPEG, JPEG 2000, OpenEXR, PDF, PNG, TIFF, GIF, ICNS, BMP, Microsoft Icon, Photoshop, PGM, PSD, PVRTC, SGI, and TGA.

    Is there a way to set OSX to display these options by default (without holding down the option key)? I’m thinking there are other “optional” features hidden away in the menus, but you can’t use them if you don’t know about them. Would be a great daily tip.

    Why do I get the feeling Apple are dumbing down everything in OS X…

  3. Mark says:

    Why ?

    Why is Apple crippling its own system? Loyal customer since 1992 but really, Leopard/Snow Leopard were superior to everything in Lion. Versioning? Perleeze.

  4. Piyush Arora says:

    That’s just pathetic. Why create a feature and hide it from users? Do we pay $2000 to play hide-n-seek or find-me-if-you-can?

  5. Paul Lee says:

    This isn’t available on my mac running mavericks.

    What a load of crap from crApple.

    • Reese says:

      This works to save GIFS and PSD files and BMP and whatever else just fine in Mavericks and OS X Yosemite, read the instructions: HOLD DOWN THE OPTION KEY when clicking the “Format” menu and you’ll see GIF and the other image formats that you can save pictures as.
