Combine Multiple PDFs

If you’d like to tweak an existing PDF beyond simply splitting it up, you’ll likely need to grab a specialized tool to do so. PDF Split and Merge is a free option that offers plenty of functionality, so it’s well worth installing on your computer.

To merge, open up the application and head to the Merge/Extract tool. Use the Add button to select the PDF files that you’re looking to merge together, using the Page Selection field to specify if there are only certain pages you want to include from an individual document.



Once everything is in place, use the Destination output file field to select where the resulting file will be saved to and press Run.

Cut Down on File Size with DjVu

PDFs aren’t known for being particularly massive in terms of file size, but a lengthy enough document might become a little unwieldy, especially if you’re looking to share it with others. To combat this, you can use a tool called PDF to DjVu GUI to keep things trim.

This utility works by converting a PDF to a different file type, the little-known DjVu — you’ll need a freely-distributed viewer to open the resulting document. As a result, it’s certainly not for everyone, but it can work wonders if you’re in desperate need of a lighter file. BetaNews has more details on how to utilize the tool if you’re curious.

To do so, head to the Tools tab of the application and locate the Fill & Sign option, using the dropdown menu to open the desired PDF. You’ll then be able to use the Sign tool to select one of several digital signature styles and sign the document.


It’s worth noting that you can also use Adobe Reader to request a signature from another user. From the Tools tab, simply select Send for Signature — although you will need to have an active Pro subscription to access this functionality.
