Apple has added enough features to make it a complete editing tool for photos and PDFs.
There are several reasons why a might need to convert an image to a PDF. In some cases, than a JPEG.
One of the most useful features of will now be saved as a PDF. Preview also lets s apply Quartz filters to a PDF file, which enhances it with colors or effects. For example, s can make a PDF black and white, increase or decrease the lightness, add a sepia, blue or gray tone, or even reduce the PDF file size. The latter is particularly useful when converting a large image file to PDF. To add any of these effects, use the Quartz filter dropdown when exporting an image to PDF in Preview.
Batch Convert Images To PDF
Preview also lets s batch convert images to PDF, provided they're all in the same format. For example, all the images will need to be either JPEG or PNG files for this method to work. To batch convert images, hold down the Command key, select all the images which need to be converted and open them in Preview. They should open in a single window. Click on the View button at the top of the window and on Thumbnails. Select all the thumbnails (use the Command+A shortcut), click on File, and then Export Selected Images. In the window that opens, click on Options. Select PDF as the format option, and then tap on Choose. The images will be saved as individual PDFs in the selected location.
Apart from converting files, Preview also offers several tools for editing PDFs. Among these is the ability to fill out PDF forms and annotate them with a signature. Text can be added and formatted by highlighting, underlining, or striking out. s can also combine multiple PDFs into one, split one PDF into different files, or delete pages from a PDF document. It's also possible to add a to a PDF or compress its file size. With so many inbuilt features available, most Mac s might not even need to third-party PDF software like Adobe Acrobat.
