Swiss army knife for PDF files
PDF toolkit provides a bunch of tools for PDF manipulation.
With PDF toolkit, you can:
Merge two or more PDF files
Convert office documents (DOCX, ODT, and many more) to PDF
Append or prepend an image to the PDF file
Download PDF files opened in tabs even as embedded documents
Don’t use this app for big files. It could be unreliable if you merge 1000 page long documents.
The conversion process could take a long time. Please wait at least 20 seconds before giving up.
