Smallpdf

A bootstrapped suite of online PDF tools that makes compressing, converting, and editing PDFs dead simple, eliminating the need for expensive desktop software. Built to solve the everyday frustration of working with clunky PDF workflows, the platform grew almost entirely through SEO by targeting high-intent search queries like "compress PDF" and "convert PDF to Word." What started as a single-purpose utility expanded into a full toolkit attracting 60 million visits per month, generating an estimated $12.5 million in annual revenue on a freemium subscription model — all without venture capital funding.
