Free and fairly full-featured editor PDFVue isn't the only webapp that can fill out PDF forms online, but it lets anyone add images, sticky notes, links, shapes, and more to forms and documents. You can head to PDFVue and upload your files for editing online, or install a Firefox extension to have the webapp be your automatic PDF handler—not necessarily a speed move, because the webapp has to download and customise anything you were taking a glance at. The editing tools are, however, pretty unique amongst PDFVue's brethren we've sampled before, like PDFMeNot and PDFHammer (what's with the fear of spacing, PDF app makers?) You get a standard range of colours to create lines, circles, text, and sticky notes with, and can upload images for branding or other purposes. The right-hand Forms tab gives you the ability to create check boxes, bullet lists, and other input data on PDFs that might otherwise seem a text-only affair. It's doubtful one would make PDFVue your full-time PDF client, but for filling out forms, hacking up a presentation, or otherwise tweaking your read-only docs, it's not a bad solution.
