Our Story

MergPDFOnline was created out of frustration with existing online PDF converters that lock basic features behind expensive subscriptions, enforce strict 5-page limits, or upload private documents to unknown cloud servers.

By leveraging modern WebAssembly and client-side JavaScript technologies, we built an engine that runs directly on your computer's processor. This gives you instant speed, unlimited file processing, and guaranteed privacy.
