Frequently Asked Questions

Do I really need a PDF reader?

If you just view PDFs occasionally, your browser is fine. If you annotate, fill forms, or read long documents regularly, a dedicated reader is worth it.

Is Adobe Acrobat Reader really free?

The basic reader is free, but Adobe constantly pushes you to upgrade to Acrobat Pro ($22.99/month). Many useful features are locked behind the paywall.

What happened to PDFGear?

PDFGear launched in 2023 and has grown rapidly (170% search interest growth). It's a legitimate, well-funded company offering a genuinely free product.

Can a PDF reader edit PDFs?

Basic readers only allow annotations (highlights, notes). For actual editing (adding text, images), you need a PDF editor.

Which PDF reader is the fastest?

Browser-based readers (ExactPDF, Chrome) load fastest since there's no application startup time. Among desktop apps, Foxit is traditionally the fastest.
