Electronically sign PDFs for free in Foxit Reader
When you need to electronically sign a PDF document this can be done for free in Foxit Reader - BUT beware there are two ways you can do this and unsurprisingly they hide the free way (called 'Fill & Sign') and make the paid (Called Foxit eSign) way more obvious!
To do this, open a PDF in Foxit, go to the 'Protect' tab on the ribbon menu and select 'Fill & Sign'
This will add a new 'Fill & Sign' tab to the ribbon menu
Click the '+' to add a new signature (this will be saved for you to use again in the future)
You can then select from the tabs to Type, Draw or Import an image of your signature. If you have a touchscreen you can sign straight into the draw tab, otherwise scan or photograph a copy of your signature and upload it through the 'import' tab.
Through the 'options' button you can convert to black and white, make it a one-time option, or password protect the use of the signature (it'll be saved to your user profile on your PC anyway so only someone logged in as you can access it).
Once you click OK your newly created signature will be available to pick straight from the 'Fill & Sign' ribbon tab.
Just click on your signature and then move the mouse over onto the document and click to place it where you need it. After you've placed it you can resize it by dragging the bottom corner of the box
When you save the document you will be prompted to apply the signatures, after which they will no longer be editable.
