What pdfFiller does
pdfFiller is a cloud-based PDF editing, e-signature, and document management platform founded in 2007 and headquartered in Brookline Village, Massachusetts, with a stated user base of approximately 56 million. The platform enables users to edit, sign, fill, convert, and manage PDFs through a browser-based editor, with native mobile applications for iOS and Android. Its product surface now extends well beyond the original editor into a generative AI suite — including AI PDF Editor, AI Document Creator, AI PDF Summarizer, Chat with PDF, and AI-powered translation with layout preservation — alongside a Form Library of more than 6.5 million legal, tax, and business documents across 30+ categories, and a PDF Tools API for developer integration. Compliance posture covers GDPR, SOC 2 Type II, PCI DSS, HIPAA, CCPA, ESIGN, and FDA 21 CFR Part 11.
The company operates a freemium-led, product-led growth model with a 30-day free trial and tiered subscriptions serving individuals, SMBs, and a 200+ employee enterprise segment, supplemented by usage-based API pricing and an affiliate/reseller channel. Distribution is materially augmented by SEO-driven micro-sites that index long-tail form categories, alongside direct integrations with Salesforce and Google Workspace. pdfFiller sits within the airSlate family of brands alongside SignNow, US Legal Forms, altaFlow, and Instapage, enabling cross-sell across workflow automation, e-signature, landing pages, and form content.
Commercial traction is evidenced by 4.6/5 average ratings across 710+ G2 reviews and Summer 2025 badges, plus a logo wall that includes Apple, Walmart, Netflix, and Tesla; these logos are framed as organic employee adoption, consistent with bottom-up PLG rather than top-down master agreements. The company is private, with no disclosed revenue, funding history, or headcount figure beyond a 501-1,000 employee range. Parent airSlate Inc. is the operating entity.
