PDFpad vs pdfFiller

Prices and features checked 20 September 2026

pdfFiller is a document workspace: your forms live in its cloud, it templates them, and it sends them out for signature. That is a real product for people who handle the same paperwork every week.

For one form that landed in your inbox, it is a subscription and an upload. Individual plans are published at $8, $12 and $15 per user per month on an annual commitment.
