There is a PDF function in Finder as well. If you select multiple files and then click on the selection, you can use Quick Actions and create PDF to do it. If you have a PDF open in Preview, you can drag any file type into the table of contents sidebar on the left to add it as an extra page. If you cannot see the table of contents, you can choose View and Table of Contents.

PDF-related functions are offered by iLovePDF.

PDF2Go is an all-purpose PDF website that can be used to convert other files to PDFs, add them from cloud storage accounts, and even point towards URLs. You can even extract text from the files you are converting with a premium account.

Both of the mobile operating systems, theAndroid and theiOS.

The first thing you should do when you get on the phone with Android is to use the app that you are creating the original file in. You can open a document with a tap on the three dots, choose Share and export, Save as, and PDF to generate a PDF, and then share it with others.

The classic print-as-PDF option is now available on the mobile device of your choice. If you find the Share button in any app, you can choose Save as PDF as the printer. To start scanning images, you need to tap the + (plus) button in the lower right corner of the main screen.
