Preview is Mac OS X's application for displaying images and Portable Document Format (PDF) documents. Like OS X itself, it comes from NeXT's OPENSTEP operating system.

Preview employs Apple's implementation of Adobe's PDF specification, and heavily uses Apple's Cocoa graphical user interface, Quartz graphics layer, and QuickTime image codec. Preview can open the following file types:

  • BMP – Windows Bitmap files,
  • DNG – Digital Negative files,
  • EPS – Encapsulated PostScript files,
  • FAX – faxes,
  • FPX - FlashPix files,
  • GIF – Graphics Interchange Format files,
  • HDR – High Dynamic Range Image files,
  • ICNS – Apple Icon Image files,
  • ICO – Windows icon files,
  • JPEG_2000 – JPEG 2000 files,
  • JPEG – Joint Photographic Experts Group files,
  • OpenEXR – OpenEXR files,
  • PS – Adobe PostScript files,
  • PSD – Adobe Photoshop files,
  • PICTQuickTime image files,
  • PDF – Portable Document Format files,
  • PNG – Portable Network Graphics files,
  • PNTG – MacPaint Bitmap Graphic files,
  • QTIF – QuickTime image files,
  • RAD – Radience Scene Description files,
  • RAW – Raw image files,
  • SGI – Silicon Graphics Image files,
  • TGA – TARGA image files,
  • TIF, TIFF – Tagged Image File Format files,
  • XBM – X BitMap files,

This gives users the ability to open a wide variety of popular and rarer image files straight out of the box. Preview offers basic image correction tools, cropping and rotation tools and annotation tools for PDF and TIFF documents. In addition, it offers keyword tools for image and PDF files. Preview can also convert between image formats; it can export to BMP, JP2, JPEG, PDF, PICT, PNG, SGI, TGA, and TIFF.
