Foxit PDF Reader vs Kiosk

Foxit PDF Reader is a free PDF reader for viewing, annotating, filling and signing PDF documents. It supports standard Acroforms and XFA forms, and its collaboration tools include shared reviews, comments and document feedback. Users can sign by hand, use a saved signature image or connect with DocuSign. The reader integrates with cloud storage services, enterprise content management systems and Microsoft SharePoint; listed business integrations include Microsoft Teams and Salesforce. Security controls include Protected View, Trust Manager, Safe Mode, ASLR and DEP. Foxit lists support for Windows 10 and 11, macOS 10.15 through 14, iOS, Android and the web. Mobile apps are available for smartphones and tablets, and desktop use can work offline. The Free PDF Reader plan costs nothing. Foxit PDF Editor is a separate product with a free 14-day trial. Help options include searchable articles, troubleshooting, ticket submission and regional phone support.

Kiosk is a free, open-source PDF reader for web, desktop, mobile, and browser extensions. It renders PDFs and offers full-text search with highlighted results, page thumbnails, zoom, and light, dark, and night display modes. Its Chrome extension adds highlighting, underlining, strikethrough, drawing, shapes, and text annotations. The project says PDFs stay on the device, with no telemetry, cloud processing, or account requirement. Android works offline after installation, and the extension release notes also state that offline use is supported. The web app can run locally or be deployed through GitHub Pages as a self-hosted instance. Desktop apps can open PDFs directly and associate Kiosk with PDF files; the extension can intercept PDFs opened in Chrome. The extension supports Chrome 88+, Edge 88+, and Brave, but not Firefox or Safari. The project is released under the MIT License. Its Android release is an early alpha, and the macOS app is ad-hoc signed but not notarized, so Gatekeeper may warn on first launch.
