| Support | Independent directory listings identify email/help-desk support, FAQs, documentation and videos. | PDFViz asks users to email support with the tool page, exact on-screen message, browser, and operating system, and says not to attach the document. |
| What it does | PDFgear provides PDF reading, editing, annotation, conversion, page management, protection, signing and AI-assisted document chat. | PDFViz is a set of free PDF tools that run in the browser tab; files are not uploaded. |
