Editing PDF (section)

=== Native display model ===
{{unreferenced section|date=November 2023}}
PDF was selected as the "native" [[metafile]] format for [[macOS]] (originally called Mac OS X), replacing the [[PICT]] format of the earlier [[classic Mac OS]]. The imaging model of the [[Quartz (graphics layer)|Quartz]] graphics layer is based on the model common to [[Display PostScript]] and PDF, leading to the nickname ''Display PDF''. The [[Preview (macOS)|Preview]] application can display PDF files, as can version 2.0 and later of the [[Safari (web browser)|Safari]] web browser. System-level support for PDF allows macOS applications to create PDF documents automatically, provided they support the OS-standard printing architecture. The files are then exported in PDF 1.3 format according to the file header. When taking a screenshot under Mac OS X versions 10.0 through 10.3, the image was also captured as a PDF; later versions save screen captures as a PNG file, though this behavior can be set back to PDF if desired.
