Case Study: Smallpdf achieves 60% organic search growth and 90% reduction in translation effort with OneSky

Smallpdf grew by 60% on search traffic while reducing 90% of time spent doing so

Smallpdf is a simple, popular SaaS PDF platform (16 tools, ~15 million monthly users) that served users in multiple languages but struggled with localization. Relying on freelance translators caused slow turnarounds, inconsistent SEO-quality translations and extra internal workload, delaying feature rollouts and harming search rankings across its 17-language sites.

After switching to OneSky in September 2016, Smallpdf automated translations and cut turnaround to 1–2 days, added three languages (Thai, Hindi, Swedish) and ensured SEO-aligned copy. The result: organic search users rose 60% (from ~6M to 9.5M monthly), Thai traffic grew over 500% in a year, translation effort fell by ~90%, and growth in key emerging markets such as China and India more than doubled.
