Here is a simple solution to create a single PDF by combining multiple files from various file types.
Assumption: I Assume you have 10 PNG files you want to combine into a single PDF file.
Note: It doesn’t matter if those ten files have different height & width dimensions.
Here is how to do this:
Step 01:
Locate & Open Preview in the Applications folder on your Macintosh
Step 02:
Select Preview. Now go to File > Open.
Step 03:
Select & Open all desired files in Preview
Step 04:
Go to View > Select Thumbnails. Now, you should see a thumbnail of all opened files in the left sidebar of your preview.
Step 05:
Select all thumbnails in the left sidebar by clicking on the first thumbnail & then pressing Command + A. Now Go to File > Export Selected Images to batch process to convert file type of all PNG files to PDF > Now click on Options > Under Format choose PDF > Click ‘Choose’ to select the destination for saving files
Step 06:
Now open that first newly created PDF file in Preview & And go to Edit > Insert > Page From File… > Now locate & select those remaining files & insert them in the current PDF file
Step 07:
Now click on Save to save your PDF with your changes and the page you inserted.
You are done with creating a single PDF by combining multiple files & documents using Preview on Mac OS X.
Hope it helps,
Thanks & Regards
