Adobe's new PDF.new, Sign.new, JPGtoPDF.new and CompressPDF.new websites are simple ways to convert Microsoft Office or image files to PDFs; create PDF forms that can be completed, signed, saved and sent; convert JPG files to PDF; and compress PDF files to reduce their size.

There's also Create.new for those who want to create social media content with the aid of Adobe Spark Post, which includes access to templates, images and icons as well as your own logos and fonts.

Sign.new will be especially useful for people who for whatever reason do not have Adobe's software – or a compatible app from another vendor – installed on their devices but need to fill in and sign PDF forms.

Sign-in via an Adobe, Apple, Google or Facebook ID is required to use these actions.

The downside is that each action can only be used once a day at no charge. But that will take care of many casual users. More frequent users are able to subscribe to one of Adobe's plans.

Adobe plans to release further free PDF actions this year, with the target of '20 in 2020.'
