About Zolvo

Who We Are

Zolvo is built and maintained by a small, independent team of developers and designers who enjoy turning everyday questions — "how many kilograms is that?", "what's my moon sign?", "can I convert this RAW photo to JPG?" — into simple, free tools that just work.

Our Mission

We believe useful tools shouldn't require an account, a subscription, or your personal data. Every calculator and converter on Zolvo is designed to be fast, free, and available to anyone, anywhere — without barriers.

How We Build

Privacy by Design

Wherever possible, our tools — especially our file converters — run entirely inside your browser. Your files and data are processed on your own device and are never uploaded to our servers. You can read more about this in our Privacy Policy.

Speed First

We keep our pages lightweight so they load quickly, even on slower connections. Heavier components, such as image format decoders, are only loaded on demand when you actually need them.

Built for the World

Zolvo is available in multiple languages, with more being added over time, so that our tools are useful to people well beyond English-speaking audiences.

What's Next

We're constantly working on new calculators and converters, often based directly on requests from people like you. If there's a tool you'd like to see, or feedback on something we've already built, we'd love to hear from you on our Contact page.
