Who We Are

Zolvo is an independent project, built and maintained by a single developer who enjoys turning everyday tasks — "can I convert this HEIC photo to JPG?", "how do I merge these PDFs without uploading them?" — 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 tool on Zolvo is designed to be fast, free, and available to anyone, anywhere — without barriers, and running entirely in your browser.
