For anyone on a Mac: all of these features in the screenshot are free with Preview. I assume OP is not, but something people should keep in mind.
- Paste images that were copied to the clipboard. Just open Preview and press CMD-N
- Split, re-arrange and merge PDF documents. Just drag pages into the sidebar
- Sign documents. Click the annotation button in the menu bar, sign either on touchpad, ipad or hold an ink signature on paper into the webcam.
- OCR (new with macOS ventura). Just click/drag/double-click on text in images.
What more did I forget?
