Free online toolkit to merge, split, compress, convert and sign PDF documents, plus desktop and mobile apps, monetized by premium subscriptions for power users and businesses.

That a free, dead-simple PDF utility could become a global business on word of mouth alone, with no investors or ads and a tiny premium tier paying the bills.

Self-funded: founder built the first version alone in 2010 and the company says it has never had investors.

Marco Grossi, an Italian-Catalan programmer, needed to cut and paste PDF content in 2010 and found the offer scarce, so he built a small service for himself. It stayed a side project until 2014, when he rebuilt everything from scratch, added more tools and published a renewed version aimed at a global audience.

The first fixed employee joined only in 2017 — Grossi calls those years 'seven years in the desert' — and growth came from word of mouth and trade shows such as Gitex rather than ad campaigns. The company added ISO 27001 certification, GDPR-aligned processing, desktop and mobile apps, and a separate e-signature brand (iLoveSign), reaching 53 staff with very low turnover.

Still independent and growing: revenue surpassed €20M in 2024 with ~40% annual growth and 850M unique users a year; in late 2025 Grossi was preparing optional AI features and customer-chosen processing regions, still with no investors.

A single, boring, universal job — editing PDFs — created a market huge enough to support a global business.

Simplicity plus trust (ISO 27001, GDPR) became the moat where competitors fought on feature bloat.

No investors meant no pressure to monetize aggressively; 99.9% free users became free distribution.

Starting as a one-person side project kept costs near zero while the product found its audience.

A consumer utility can reach global scale without investors or a growth team if the product is so simple it sells itself — but the free-to-paid ratio has to be engineered on purpose.

As of 2026-09-02 iLovePDF still operates from Barcelona with no outside investors and Marco Grossi as CEO. In late 2025 the company was preparing optional AI features, customer-chosen data-processing regions, and the growth of iLoveSign, while maintaining roughly 40% annual revenue growth and a position among the world's 50 most-visited sites.
