Free stuff I cannot do without: Combine PDFs

What do you do when you have scanned pages from a book and the pages are in three separate files, in every which rotation because that was the way the book fit on the scanner, and all you want is a single correctly-rotated PDF file?

Use Combine PDFs. (Mac-only)

Combine PDFs lets you merge different PDF files, remove unwanted pages, and rotate individual pages within the file to create a single, well-organised PDF.



What you do is to click on the "Add File" button at the bottom left of the start-up screen. Then you choose the PDF file you want to edit. Do this for as many PDF files you would like to merge.

The individual pages of each file will open in the main section. The two left columns indicate the file name and page number of the original PDFs. If you wish you rotate a single page, select the page and click "Command-R". If you wish to delete a page, select it and click "delete". You can change the order of the pages by dragging and dropping individual pages.

When you are done, type in the name of your final PDF and click "Merge PDFs".

It's as simple as that. Now if only it would let me crop the pages too!
