PDFsam Basic merges, splits, rotates and extracts PDF pages on your computer; its page operations do not require uploading the files. It earns seventh for assembling reading packets and putting scanned pages in order.
It beats #8 on usefulness across ordinary assignments, but #6 supports broader visual work. Choose the free Basic product; the same site also offers other products. Check page order before submitting a merged file. This recommendation concerns page arrangement, rather than rewriting paragraphs inside a PDF.
