About Convert.Online

Convert.Online is a SaaS platform dedicated to advanced file conversion and compression. It is owned and operated by Kefalica DOO, a Serbian software company with an international presence. Whether you are a casual user or a developer integrating our API, our team is committed to providing you with reliable, high-quality support.

Our Mission

We want file conversion to be simple and reliable for everyone — students, creators, and professionals. Our goal is to provide a fast, browser-first toolset that preserves user privacy and keeps workflows moving.

Why we built it

Converting files used to mean installing software, waiting for long uploads, or dealing with confusing UIs. Convert.Online removes those barriers with a modern web experience and powerful backend conversion tools.

What we offer

  • Support for 400+ file types and 49,000+ format combinations
  • Advanced options (codec, resolution, bitrate) when you need them
  • Auto-delete files after 24 hours — privacy by default
  • Cross-device support — works in any modern browser
